WARNING
Validity of safety parameters
The safety parameters in the technical specifications are valid for a mission time of 20 years and
a repair time of 100 hours. If a repair is not possible within 100 hours, remove the relevant
module from the terminal block or switch off its supply voltage before 100 hours elapse. After
100 hours elapse, the module switches off on its own.
For repairs, follow the procedure described in section "Diagnostic messages (Page 60)".
(FDIW-001)
Output disable switch
If you want to pull the I/O module in runtime, you have to press the output disable switch for 3
seconds for the I/O module to be deenergized.
When the output disable switch has been pressed for 3 seconds, the LED DIAG flashes red, the
LED MT lights up yellow and the I/O module generates a diagnostics message. You can find
additional information in section "Status and fault displays of the F-DI 16x24VDC HA I/O module
(Page 55)".
Note
Pressing the output disable switch interrupts any ongoing firmware update. A firmware update
cannot be performed when the device is deenergized.

Description of parameters
5.2.1
F-parameters
F_source_address
Together, the F-source address "F_source_address" and the F-destination address
"F_destination_address" form the PROFIsafe address. The PROFIsafe address is used for the
unique identification of the F-I/O modules.
The F-source address is a unique address of the fail-safe CPU for the entire network. In S7 F/FH
systems, it is automatically preset with the value "1" and cannot be changed in the properties of
the I/O module.
F_destination_address
Together, the F-destination address "F_destination_address" and the F-source address
"F_source_address" form the PROFIsafe address. The PROFIsafe address is used for the unique
identification of the F-I/O modules.
Station-wide uniqueness:
• The F-source address "F_source_address" of the F-CPU is unique station-wide. In S7 F/FH
systems, it is automatically preset with the value "1".
• The F-destination address of the F-I/O module is automatically unique station-wide.
To prevent an incorrect parameter assignment, a station-wide unique F-destination address
is automatically assigned when the F-I/O module is placed in HW Config.
If you change F-destination address, the station-wide uniqueness of F-destination address is
automatically checked.
You must assign the F-destination address to the F-I/O module before you commission it.
Note
Requirement for type R1 system redundancy
With type R1 system redundancy for distributed I/O, the left interface module must be
plugged in so that a new F_destination_address can be assigned to the module.

Equipment Manual, 01/2021, A5E45647528-AC
Parameters/address space
5.2 Description of parameters
WARNING
PROFIsafe addresses have to be unique for the station
• Station-wide uniqueness:
Fail-safe I/O modules of the ET 200SP HA are uniquely addressed station-wide by a
combination of F-source address (PROFIsafe basic address of the assigned F-CPU) and Fdestination address. The F-system itself ensures that the F-destination addresses of all F-I/O
modules within the assigned F-CPU are unique.
• Cross-station uniqueness:
To guarantee uniqueness across stations, you must verify that the PROFIsafe addresses
("F_source_address" + "F_destination_address") of the F-I/O modules are unique across
stations.
• Verification following a change:
Because the F-source address "F_source_address" of the PROFIsafe address of the F-CPU is
automatically set to "1", you can only change the preset address "F_destination_address" for
F-I/O modules of the ET 200SP HA.
Note that the PROFIsafe address of the F-I/O module must be unique across all stations!
For Ethernet subnets and mixed configurations of PROFIBUS and Ethernet subnets, the
following also applies:
The combination of F-source address and F-destination address of all F-I/O modules only has to
be unique throughout the Ethernet subnet including all lower-level PROFIBUS subnets, under
the exclusion of cyclic PROFINET IO communication between Ethernet subnets.
(FDIW-002)
F_monitoring time (ms)
With this parameter you set the monitoring time for safety-related communication between the
F-CPU and F-I/O (PROFIsafe monitoring time) for safety operation.
The parameter is assigned a default value, but you can change it.
The configured F-monitoring time influences the response time of the system to a system error.
For this reason, the selected time must be as short as possible, but still long enough to prevent
timeouts when no error is occurring.

and thus allow a higher-level setting.
Note
Due to dependencies, the parameters of the channels can be reset to default values if crosschannel parameters are changed.
Therefore, check the setting of the channel parameters after changing a cross-channel

Parameters/address space
5.2 Description of parameters
5.2.4
Parameters of the channel pairs
Sensor evaluation
You select the type of sensor evaluation with the "Sensor evaluation" parameter:
• 1oo1 evaluation
With 1oo1 evaluation one sensor is connected.
The sensor occupies one input channel.
• 1oo2 evaluation, equivalent/non-equivalent
With 1oo2 evaluation equivalent/non-equivalent, two input channels are occupied by one of
the following:
– A two-channel, equivalent/non-equivalent sensor
– Two single-channel sensors
The input signals are compared internally for equivalence or non-equivalence.
Note that in 1oo2 evaluation, two channels are grouped into a channel pair. The number of
available process signals of the F-module is reduced accordingly.
The evaluation result for the channel pair is available at the input of the channel with the low
channel number (channel "n").
Dependencies:
• If the "1oo2 evaluation, equivalent" or "1oo2 evaluation, non-equivalent" option is selected
for the "Sensor evaluation" parameter, the "Input delay (ms)" of a channel must be less than
the configured "Discrepancy time (ms)".
Discrepancy analysis:
If you are using a two-channel sensor or two single-channel sensors that measure the same
process variable, the response of the sensors will be delayed relative to one another due to the
limited precision of their arrangement, for example.
The discrepancy analysis for equivalence/non-equivalence is used for fail-safe inputs to detect
errors from the time sequence of two signals of the same functionality. The discrepancy analysis
is started when different levels are detected for two associated input signals (when testing for
non-equivalence: the same level). On expiration of a configurable time interval, i.e. the so-called
discrepancy time, a check is made to determine whether the difference in the signal levels has
disappeared (when testing for non-equivalence: the equivalence of the signal levels). If not,
there is a discrepancy error.
Sensor supply for 1oo2
You use this parameter to select the sensor supplies for 1oo2 evaluation:
• Each sensor has its own sensor supply
• Both sensors on one sensor supply
In this setting, the sensor supply of the channel with the low channel number (channel "n")
is used, for example, the sensor supply of channel "0" is used for channel pair 0/8.

Equipment Manual, 01/2021, A5E45647528-AC

Parameters/address space
5.2 Description of parameters
Discrepancy behavior
Requirement:
You have configured the following:
• "Sensor evaluation": "1oo2 evaluation, equivalent" or "1oo2 evaluation, non-equivalent"
Function:
For "Discrepancy behavior", you configure the value that is supplied to the safety program in the
F-CPU during the discrepancy between the two affected input channels, i.e. while the
discrepancy time is running. You configure the discrepancy behavior as follows:
• "Supply last valid value"
• "Supply 0 value"
Option "Supply last valid value":
The last valid value (old value) before the discrepancy occurred is supplied to the safety program
in the F-CPU as soon as a discrepancy is detected between the signals of the two affected input
channels. This value is supplied until the discrepancy disappears or the discrepancy time expires,
and a discrepancy error is detected. The sensor-actuator response time is correspondingly
extended by this time.
This means that the discrepancy time of connected sensors with 1oo2 evaluation must be
matched with short response times for fast responses. Accordingly, it makes no sense, for
example, when connected sensors with a discrepancy time of 500 ms trigger a time-critical
shutdown. In the worst-case scenario, the sensor-actuator response time is extended by an
amount equal to the discrepancy time, which you can calculate in section "Response times":
• For this reason, arrange the sensors in the process in such a way as to minimize
discrepancy.
• Then, select as short a discrepancy time as possible that also has a sufficient margin to
prevent false triggering of discrepancy errors.
Option "Supply 0 value":
The value "0" is supplied to the safety program in the F-CPU as soon as a discrepancy between
the signals of the two affected input channels is detected.
If you have configured "Supply 0 value", the sensor-actuator response time is not affected by the
discrepancy time.
Discrepancy time (ms)
Requirement:
You have configured the following:
• "Sensor evaluation": "1oo2 evaluation, equivalent" or "1oo2 evaluation, non-equivalent"
In most cases, the discrepancy time is started but does not completely elapse because the signal
differences even out after a short time.
Select a sufficiently long discrepancy time so that in the error-free case the difference between
the two signals always disappears before the discrepancy time expires (when testing for nonequivalence: the equivalence of the two signals).

F-DI 16x24VDC HA
Equipment Manual, 01/2021, A5E45647528-AC
Parameters/address space
5.2 Description of parameters
Function:
You can specify the discrepancy time for each channel pair.
Behavior while discrepancy time is running:
While the configured discrepancy time is running inside the module, the affected input channels
supply either the last valid value or "0" to the safety program in the F-CPU, depending on the
configured discrepancy behavior.
Behavior after expiration of the discrepancy time:
If after expiration of the configured discrepancy time the input signals are still different (when
testing for non-equivalence: input signals are still the same), e.g. due to a sensor wire break, a
discrepancy error is detected and the diagnostics message "Discrepancy error" is generated
along with information on the faulty channels.
Reintegration after discrepancy error
Requirement:
You have configured the following:
• "Sensor evaluation": "1oo2 evaluation, equivalent" or "1oo2 evaluation, non-equivalent"
Function:
You use this parameter to specify when a discrepancy error is regarded as corrected, thus
enabling reintegration of the affected input channels. You have the following parameter
assignment options:
• "Test 0-Signal necessary"
• "Test 0-Signal not necessary"
Option "Test 0-Signal necessary":
If you have configured "Test 0-Signal necessary", a discrepancy error is not regarded as corrected
until a 0-signal is present again at both of the affected input channels.
If you are using non-equivalent sensors, i.e. "Sensor evaluation" is set to "1oo2 evaluation, nonequivalent", the result of the channel pair must be "0" again.
Option "Test 0-Signal not necessary":
If you have configured "Test 0-Signal not necessary", a discrepancy error is regarded as corrected
when a discrepancy is no longer present at both of the affected input channels.

Parameters of the channels

Parameters/address space
5.2 Description of parameters
Diagnostics: Wire break
Enables the wire break test. The wire break test must be activated for wire break detection to take
place.
Input delay (ms)
To suppress injected interference, you can set an input delay for a channel or channel pair.
Interference pulses whose pulse time is less than the set input delay (in ms) are suppressed.
Suppressed interference pulses are not visible in the process image input (PII).
A long input delay suppresses longer interference pulses but results in a longer response time.
Dependencies:
• The values available for the input delay depend on the "Time for short-circuit test (ms)" of the
configured sensor supply.
• The value "Time for short-circuit test (ms)" must be more than twice as large as the
configured "Input delay (ms)".
• The "Input delay (ms)" of a channel must be less than the configured "Discrepancy time (ms)"
if the "1oo2 evaluation, equivalent" or "1oo2 evaluation, non-equivalent" option is selected
for the "Sensor evaluation" parameter in the respective channel pair.
In 1oo2 evaluation, the input delay of the lower-order channel (channel n) also applies
automatically to the higher-order channel (channel n+8).
Note
Due to physical properties, crosstalk of signals can occur on longer unshielded signal wires (see
section "Electromagnetic compatibility" in system manual Distributed I/O System ET 200SP HA
(https://support.industry.siemens.com/cs/ww/en/view/109761547)).
Adjust the input delay or use shielded signal wires to avoid possible passivation of fail-safe digital
inputs and shutdown of the sensor supply.
Pulse stretching (s)
Pulse stretching is a function for extending a digital input signal. A pulse on a digital input is
extended to at least the configured length. If the input pulse is already longer than the
configured length, the pulse is not changed.
How the fail-safe input module works:
The fail-safe input module only stretches pulses with the value "0". That is because the safety
concept is based on existence of a safe state for all process variables. For digital F-I/O, this is the
value "0". This applies to sensors and actuators. Impulses with the value "1" are ignored.
With "1oo2" evaluation, the first pulse with value "0" triggers pulse stretching.
After pulse stretching starts, further impulses with the value "0" are ignored.
Principle:
The following figure shows pulse stretching of the fail-safe input module.

Parameters/address space
5.2 Description of parameters
Note
If you configure pulse stretching for an input channel, it also affects chatter monitoring enabled
for this channel. The "pulse-stretched" signal is the input signal for chatter monitoring. This
means you need to adapt the parameter settings of pulse stretching and chatter monitoring to
each other. You can adapt the functions to your process by selecting the appropriate parameter
values.
Flutter monitoring
Function:
Flutter monitoring is a process control function for digital input signals. It detects and reports
unusual signal sequences for the process, for example, too frequent input signal changes
between "0" and "1", during 1oo1 evaluation. If signal characteristics like these occur, it is a sign
that the sensors are faulty or that there are instabilities from a process engineering viewpoint.
Recognizing unusual signal patterns:
A configured monitoring window is available for each input channel. A monitoring window is
started every time the input signal changes. If the input signal changes within a monitoring
window more often than the configured "Number of signal changes", it is recognized as a
flutter error. If no flutter error is detected within the monitoring window, the monitoring
window is restarted at the next signal change.
If a flutter error is detected, a diagnostics message is output. When the flutter error does not
occur for three times the configured monitoring window time, the diagnostic is reset.
Principle of flutter monitoring:
The following figure shows the principle of flutter monitoring.

An internal sensor supply must be selected for use of the short-circuit test.
Dependencies:
• If the following conditions are fulfilled at the same time, then the "Sensor supply" parameter
for channel "n+8" is set to "external" and cannot be edited. The setting of the sensor supply
for channel "n" remains editable.
– With the "Sensor evaluation" parameter, the option "1oo2 (2v2) evaluation, equivalent"
or "1oo2 (2v2) evaluation, non-equivalent" is selected.
– With the parameter "Sensor supply for 1oo2" the option "Both sensors on one sensor
supply" is selected.

Parameters/address space
5.2 Description of parameters
Short-circuit test
Here, you enable the short-circuit detection for the channels of the F-module for which one of
the internal sensor supplies is set.
The short-circuit test only makes sense if an internal sensor supply is set. A short-circuit test is
not possible for sensors with power supply, e.g. 3-/4-wire proximity switches.
The short-circuit detection briefly switches off the sensor supply. The switch-off duration is the
same as the configured "Time for short-circuit test (ms)".
If a short-circuit is detected, the F-module triggers a diagnostic interrupt in the F-CPU and the
input is passivated.
The following short-circuits are detected:
• Input shorted to L+
• Input shorted to a sensor supply of another channel
• Sensor supply shorted to M
Also detected with disabled short-circuit detection if the sensor supply is configured
"internally".
When a 1 signal is active at the input, the following short-circuits are also recognized:
• Short circuit on an input with the input of another channel
• Sensor supply shorted to sensor supply of another channel
• Short circuit of a sensor supply to L+
If the short-circuit test is disabled, you must route your cables in a short-circuit-proof and crosscircuit-proof manner.
Note
During the execution time of the short-circuit test ("Time for short-circuit test (ms)" + "Startup
time of sensor after short-circuit test"), the last valid value before the start of the short-circuit
test is passed to the F-CPU. Activation of the short-circuit test thus affects the response time of
the respective channel or channel pair.
Time for short-circuit test (ms)
When the short-circuit test is enabled, the corresponding sensor supply is switched off for the
configured time. If the module does not detect a "0" signal at the input within the configured
time, a diagnostics message is generated.

Equipment Manual, 01/2021, A5E45647528-AC
Parameters/address space
5.2 Description of parameters
Note the following for the parameter assignment:
• If the channel is passivated, this can also be due to excessively high capacitance between the
sensor supply and input. This consists of the capacitance per unit length of the cable and the
capacitance of the employed sensor. If the connected capacitance is not discharged within
the configured time, you must adjust the "Time for short-circuit test (ms)" parameter.
• Dependencies:
– The values available for the input delay depend on the "Time for short-circuit test (ms)" of
the configured sensor supply.
– The value "Time for short-circuit test (ms)" must be more than twice as large as the
configured "Input delay (ms)".
Startup time of sensor after short-circuit test (ms)
Requirement:
The short-circuit test is enabled.
Function:
In addition to the switch-off time "Time for short-circuit test (ms)", a startup time must also be
specified for performing the short-circuit test. You use this parameter to notify the module how
long the utilized sensor needs to start up after the sensor supply is switched on again. This
prevents an undefined input state due to transient reactions in the sensor.
Note the following for the parameter assignment:
• This parameter must be greater than the transient recovery time of the employed sensor.
• Because the configured time affects the response time of the module, we recommend that
you set the time as short as possible but long enough for reliable transient recovery of your
sensor.

Note
• You may only access the addresses occupied by user data.
• In S7 F/FH systems, the value status is automatically processed by the F-channel drivers.
• With I/O redundancy, you only access the channels of the left I/O module. The input values
of the corresponding channels of the redundant I/O module are automatically processed by
the F channel drivers.
• For 1oo2 sensor evaluation, the two channels are combined, e.g. channel 0 (input bit DI0)
with channel 8 (input bit DI8). With 1oo2 evaluation of the sensors, you may only access the
input bit of the lower channel number in the safety program, in this example channel 0.
• The other address areas occupied by the F-modules are assigned for functions including
safety-related communication between the F-modules and F-CPU in accordance with
PROFIsafe.

For each input signal, the F-DI 16x24VDC HA module provides information on its validity, the
"value status" (qualifier bit). The value status is stored in the process image of the inputs.
In S7 F/FH Systems, you may only access the addresses (DIx) occupied by user data. The value
status is automatically processed by the F-channel drivers.

Achievable safety class
The achievable safety class depends on the sensor quality and the proof-test interval according
to the IEC standard 61508:2010. If the sensor quality is not as high as required by the required
safety class, the sensor must be used redundantly, have a 2-channel connection and 2-channel
evaluation.

Wiring
You perform the wiring on the appropriate terminal block. You can find additional information
on this in section "Pin assignment of the F-DI 16x24VDC HA I/O module (Page 15)".
Sensor supply
The sensor must be supplied internally by at least one channel for application 3.1.
The sensor can be supplied internally or externally for application 3.2.
Requirements for applications in machine protection with Cat.4
Both conditions must be met for applications in machine protection with Cat.4:
• The wiring between sensors and automation system and between automation system and
actuators must be designed to state-of-the-art engineering and standards to prevent short
circuits.
• The sensors are wired as shown in the sections Application 3.1 (SIL3/Cat.4/PLe) (Page 47)
or Application 3.2 (SIL3/Cat.4/PLe) (Page 48). You only need to detect one short circuit
because two faults are required to generate it. This means both signal cables in short circuit
have an isolation fault. A multiple short circuit analysis is not required.
Procedures for locating all short circuits are also permitted if single short circuits are not located.
One of the two conditions must be met for this purpose:
• Short circuits may not corrupt the read signals compared to the sensor signals.
• Short circuits cause a corruption of the read signals compared to sensor signals in the
direction that ensures safety.

General sensor requirements
For safety-related use of sensors, you must observe the following important warning:
WARNING
Sensor requirements
Note that a significant responsibility for safety of instrumentation lies with the sensors. Also
keep in mind that sensors generally do not have proof-test intervals of 20 years according to
IEC 61508:2010 without a significant loss of safety.
The probability of dangerous faults or the rate of dangerous faults of a safety function must
adhere to an SIL-dependent upper limit.
You will find the values achieved by the F-modules in their technical specifications.
To achieve the respective safety class, correspondingly qualified sensors are required.
(FDIW-010)
Additional sensor requirements
The following table shows which safety class can be implemented with a given sensor
configuration.

WARNING
Safe response of the safety program when the sensor has "0" status
In the case of fail-safe input modules, the value "0" is passed to the F‑CPU after detection of
faults. Therefore you must ensure that sensors are implemented in such a way that the safety
program reacts safely to a "0" state of the sensors.
Example: The safety program of the EMERGENCY OFF sensor must ensure the opening action
on the affected actuator with "0" state (EMERGENCY OFF pushbutton pressed).

6.5 Requirements placed on sensors for fail-safe modules
Requirements for the duration of the sensor signals
WARNING
Sensor signal requirements
Observe the following requirements for the sensor signals:
• To guarantee the correct acquisition of the sensor signals by F-modules with inputs, you
must ensure that the sensor signals have a certain minimum duration.
• So that pulses are reliably detected, the time between two signal changes (pulse duration)
must be greater than the PROFIsafe monitoring time.
(FDIW-012)
Reliable acquisition by F-modules with inputs
The minimum duration of the sensor signals for F-modules with inputs is dependent on the
configured input delay, the parameters of the short-circuit test of the sensor supplies and the
configured discrepancy behavior for 1oo2 (2v2) evaluation.
The duration of the sensor signal must be longer than the maximum response time of the
configured application case. For information on calculating the maximum response time, refer
to section "Response times" of the respective F-module.
The minimum durations yield the maximum permissible switching frequency of the sensor
signals.
Technical specifications of the sensors
Also refer to the device manuals of the F-modules for information on the technical
specifications for selecting the sensors.

IO redundancy
Overview of IO redundancy
For the configuration of IO redundancy, you insert 2 F-DI 16×24VDC HA I/O modules of the same
type next to each other on a redundant block. You can find additional information on the possible
terminal blocks in section "Terminal blocks for the I/O module (Page 13)".
This terminal block connects the respective process signals of the two modules to a common
process terminal.
• The wiring work is lower compared to connecting separate I/O modules, because the
interconnection of the process signals is integrated into the system.
• The redundant signal processing of the sensors at module level increases the availability of
the system.
Note
IO redundancy is briefly described below.
You can find detailed information on this in system manual ET 200SP HA Distributed I/O System.
Configuration and use
For configuration and use of F-DI 16×24VDC HA I/O modules in IO redundancy, the following
requirements apply:
Selection of hardware:
• Redundantly used I/O modules must be identical. This means they must have the same article
number, the same firmware version, and a compatible hardware version.
Installation:
• I/O modules of the same type are plugged in pairs next to each other in the same redundant
terminal block (type "TB45R-P32").
IO redundancy:
• The master module must always be configured at an even slot, the slave module at the
following odd slot.
• The two redundant I/O modules operate simultaneously and independently. Both modules
generate diagnostics, interrupts, messages, process values, etc.
Configuration:
• Assign the redundancy parameters for the I/O module.
• The settings you make for an I/O module always apply to the module pair.
Response to failure
If an I/O module or a channel fails, the following applies to one of the two I/O modules:
• Error-free inputs remain available in the system.

Diagnostic messages
Overview
The F-module generates a diagnostic interrupt for each diagnostics message described in the
following table. In addition, the DIAG LED on the I/O module flashes red or the MT LED lights up
yellow.
In addition, channel-specific diagnostics are indicated by the corresponding channel fault/status
LEDs.
The diagnostics messages can be read from the diagnostics buffer of the CPU, for example.
Module faults are indicated as diagnostics (module status).
After fault correction, you must reintegrate the F-module in the safety program.
You can find additional information on passivation and reintegration of F-I/O in the
programming and operating manual "SIMATIC Industrial Software S7 F/FH Systems Configuring and Programming (https://support.industry.siemens.com/cs/ww/en/view/

Note
Note *1) for the messages "Overload or internal sensor supply short-circuit to ground"
(307H) and "Wire break" (6H)
With incoming diagnostics message "Overload or internal sensor supply short-circuit to ground",
a wire break (incoming/going) may also be signaled. The wire break signal (6H) can be ignored
in this case.
Supply voltage outside the nominal range
If the supply voltage P is outside the specified value range, the DIAG LED flashes and the module
is passivated.
After subsequent voltage recovery (level must be within the specified value range for at least 1
minute (see section "Technical specifications (Page 67)": Voltages, currents, potentials), the
DIAG LED stops flashing. The module remains passivated and waits for user acknowledgment.
Behavior in case of cross circuit/short circuit to the sensor supply
With configured internal sensor supply and deactivated short-circuit test, M short-circuits to the
sensor supplies are detected. Channels for which the relevant sensor supply is configured will be
passivated.
Short-circuits from ground to the sensor supply are detected for a configured internal sensor
supply and activated short-circuit test. Channels for which the relevant sensor supply is
configured will be passivated.
Special features for fault detection
The detection of some faults (e.g. short-circuits, discrepancy errors) depends on the application,
the wiring, the configuration of the short-circuit test and the configuration of the sensor supply.
You can find the corresponding tables for fault detection for the applications in section
"Applications of the F-I/O module (Page 39)".
General information on diagnostics
You can find additional information on diagnostics that pertains to all F-modules (e.g. readout
of diagnostic functions, passivation of channels) in the programming and operating manual

Introduction
The response times of digital input module F-DI 16x24VDC HA are found below. The response
times of the digital input module go into the calculation of the F-system response time.
Definition of response time for fail-safe digital inputs
The response time represents the interval between a signal change at the digital input and
reliable availability of the safety frame on the backplane bus.
Times required for the calculation
• Max. cycle time: Tcycle = 6 ms
• Max. acknowledgment time (Device Acknowledgement Time): TDAT = 12 ms
The maximum response time when a fault is present (One Fault Delay Time, OFDT) corresponds
to the maximum response time under fault-free conditions (Worst Case Delay Time, WCDT).
Maximum response time under fault-free conditions (Worst Case Delay Time, WCDT), with 1oo1
evaluation
• The following formula applies to a sensor supply without short-circuit test:
t <= 2 * Tcycle + Input delay
• The following formula applies to a sensor supply with short-circuit test:
t <= 2 * Tcycle + Input delay + T1 + T2
T1
T2
Time for short-circuit test
Startup time of the sensor after the short-circuit test
Maximum response time under fault-free conditions (Worst Case Delay Time, WCDT), with 1oo2
evaluation
• The following formula applies to a sensor supply without short-circuit test:
t <= 2 * Tcycle + Input delay + Discrepancy time*)
• The following formula applies to a sensor supply with short-circuit test:
t <= 2 * Tcycle + 2 * Input delay + max. (T1p + T2p, T1s + T2s) + Discrepancy time*)
