Description
ral
Y04 is a humidity and temperature sensor powered entirely from the two-wire
SIOX communication bus while Y04-1 uses a separate power supply.
Temperature is measured between -40,0 *C and +80,0 *C while relative
humidity is measured between 10 % and 95 %.
Both Y04 and Y04-1 contain a relative humidity sensor and an NTC resistor
(Negative Temperature Coefficient) used as temperature sensor. These
sensors are located at the tip of the module (to the right in the picture above).
The internal firmware presents the values read from these sensors with a
resolution of 0,1 *C and 0,1 %, respectively. The Y04-1 has a connector for an
additional NTC sensor and a relay output. The relay output is closed when no
power is supplied to the module.
Both modules include an internal PLC (Programmable Logic Controller) for
application specific programs. The PLC is described in an additional manual
called “SIOX Programmable Controller”.
The modules also contain a reed switch at the tip of the module that is used for
sequential addressing and default setting, see “Address setup”.
Care should be taken not to expose the module to liquid water since the
humidity sensor will be permanently affected by this, thus invalidating the
factory calibration.

The SIOX modules should be interconnected through a two-wire, low capacitance
twisted pair. Shielded cables may be used, but unless a correct strategy for shield
grounding is adopted, it may prove to be of little benefit. Instead, the capacitance
between the shield and the bus wires will add to the total capacitive load on the
SIOX bus and decrease the maximum distance over which communication can be
carried out for a given bit rate. The total resistance of the bus should not be higher
than 2 * 50 (.
The module is preset at the factory to communicate at 4800 bits/s and the address
set to 1. General principles for the SIOX bus and communications are discussed
in a separate manual, the "SIOX System Description". Changes in operation modes
are brought about by Parameter Setup Strings communicated over the SIOX bus.

Y04-1 has eight screw terminals for 0,14 - 1,0 mm2 cable (see picture below). The
Relay switch can be controlled by the internal firmware or by the internal PLC, see
“Relay output”.
The NTC temperature sensor connected to the “External NTC” terminals should
have a nominal resistance of 10 k( at 25 *C and a B factor of 3900 for the internal
firmware to calculate the correct temperature from this sensor (for instance
Betatherm 10K3A1B) .
The SIOX communication terminals for Y04-1 are polarised so care should be
taken to connect the SIOX bus with the right polarity.
Y04-1 requires an external DC power supply with a voltage of 24 to 48 Volts.

Parameter Memory
Communications
The Y04 contains two types of memory: RAM for temporary storage for as long as
the module is connected to a power supply, and EEPROM for long-term storage
of working modes, parameters and initialization values after a power disconnect.
At power-up, the EEPROM variables are automatically copied to the RAM, and the
information is used to control the module. All EEPROM setup values may be
copied again if data = FFFF16 is written to the first parameter number 0/0/. This
initiates a full soft reset, without changing the value in the EEPROM for this
parameter.
Y04 communicates as a slave in normal SIOX buses using speeds from 300 to
19200 bits/second. To change communication speed, send a Setup String
command setting the station's EEPROM parameter 0/0/. Note, that the speed will not
change until after a power-down/power-up cycle has been carried out or a Soft
Reset (FFFF16) in this parameter.
By using String Mode commands any variable may be read or modified at any
time* either temporarily in RAM or permanently in EEPROM. In the latter case, the
corresponding RAM cell is modified as well. Information in controlling parameters
will immediately affect the function of the module.
* Parameters 5, 6, 7, $0/E and $0/F holds calibration data and are locked. They can
only be changed by setting the ‘Write All’ flag (bit 16 in parameter 0/). This is the
Most Significant bit in the parameter, refer to page 12.

Magnetic Switch
The module includes a reed switch which can be activated by placing a magnet on
the Y04 approximately 10 mm from the tip. If the switch is active when power is
applied to the SIOX bus and released within 3 seconds, the module enters a
“default” mode. The address is set to 63, the bit rate to 4800, PLC and any options
are disabled. In this way, an Y04 with unknown speed or address or colliding with
another module can be accessed and the correct settings entered.
Follow these steps to recover a “lost” module:
1. Disconnect power.
2. Apply a magnet to the tip of the module (closing an internal reed switch).
3. Reapply power and remove the magnet within 3 seconds. The module will now
communicate at 4800 bits/s on address 63 with the PLC and any options
disabled.
4. Check and reconfigure the module for proper operation.

Address setup
Group Address
Parameter 0/1 contains the module address in bits 14 - 9. Changing the address will
cause the module to occupy another address on the SIOX bus. Address 0/ is not
a valid address so setting the address to 0/ will revert the address to 63 (3F16).
Large SIOX systems may contain more than 63 modules. In this case an extra
group address character may be added to string setup messages to allow 63*63
modules. Y04 can be set to respond to a group address by setting the option x4xx
in parameter 0/2 and the Group address xx0/1 -xx3F in parameter 0/0/. The unit will
immediately readdress itself.
Parameter 0/1: (0/10/0/16)
0/1 - 3F = Module address
55IJ IJIJ 5555 5555
0/1 - 3F = Group address
5555 5555 55JI JIJI
(option x4xx in Parameter 2 must be set)
There are two ways of setting up the address in the internal EEPROM in the
module. If a module is connected to a SIOX bus which includes a master, typically
a PC or a SIOX operator terminal, this master can search for the module and, when
found, send a command to change the address. The typical PC program for this
is the Visual Setup for Y04: Y04setup.dff
Alternatively, a special Sequential Addressing command can be sent to a group
of already installed modules using the SIOX Sequential Addressing software*. If a
magnet is applied to the tip of a Y04 module (closing the internal reed-switch) when
it has received this command, the module accepts the command and saves the
included address in its EEPROM. The module then sends an acknowledge to the
master. The master now typically sends the addressing command again but now
with the next address in the chain, and the next module can be handled. Finally all
modules have received individual addresses regardless of their former set-ups and
the master stops sending Sequential Address commands. Should the chain be
incorrect, the whole sequence can be restarted.
Follow these steps:
1.
2.
3.
4.
5.
Start the software "SIOX Sequential Addressing tool".
Press F6 and make sure that the communication settings are correct.
Press start.
The start address can be changed by the "skip"-button
Now apply a magnet to the tip of the first Y04
(will have the first address) for a duration of approximately one second and then
remove it.
6. Continue with next module until all modules are configured.
* The addressing tool can be downloaded on our website.
SIOX Message Transfer
Two types of SIOX messages are accepted: Data Mode or String Setup Mode.
A Data Mode Communication is a minimum two-way communication between the
central and a module. Data Mode affects the seven least significant bits in
parameter 0/8 and the answer is the 14 least significant bits in parameter 0/9.
String Mode Communications use the same address as Data Mode but permit
access to all functions in the module.
Data Mode transfers are less reliable than String Mode, and in some cases a Data
Mode message could inadvertently change the relay state. Therefore, setting bit
14 in parameter 0/0/ inhibits any changes by Data Mode, although a correct answer
will still be returned.
Measurement Results
The results from the humidity and temperature measurements are stored in
parameter 38, 39 and 3A. The results are scaled by a factor of 10 e.g. a result
value of 213 (0/0/D516) in parameter 38 corresponds to a measured temperature of
21,3 *C.

Internal Temperature Offset (*)
Humidity Gain / Offset (*)
This parameter permit offset control of the internal temperature value, normally
expressed in tenths of *C. The Offset is added to the measured internal
temperature and the result is stored in parameter 38. It is typically used if a small
correction shall be made to the temperature value.
These parameters permit offsetting and scaling of the relative humidity value,
normally expressed in tenths of %. The Gain is multiplied with the measured
relative humidity and the Offset is then added to the product. Gain should normally
be set to 0/0/0/0/. Offset is used to fine trim the humidity value during calibration. The
result from these operations is stored in parameter 39.
The Offset uses 2:s complement representation, so an offset value of FFFF16
corresponds to a decimal value of -1 (-0.1 *C), FFFE16 corresponds to a decimal
value of -2 and so on. An offset value of 0/0/0/1 corresponds to 1, 0/0/0/2 to 2 and so
on. This gives an offset value range from -32768 to +32767 (80/0/0/ - 7FFF).
Gain = 10/0/0/16 corresponds to a multiplication by 1, 0/0/0/116 corresponds to a factor
of 1/4096 and FFFF16 is equal to a factor of 65535/4096 + *16. Default Offset and
Gain values = 0/0/0/0/ do not modify the temperature readout.

Dewpoint Calculation
The firmware calculates the dewpoint by measuring the internal temperature and
the relative humidity. The vapour pressure is then acquired from an internal table
using the measured temperature as input.
The dewpoint temperature is then calculated from this vapour pressure.
The “Internal dewpoint adjust” byte is then added to this temperature (with sign)
and the “External dewpoint adjust” byte is added to the external temperature
reading. If the internal temperature (with adjustment) is above 0 *C and the
external temperature (with adjustment) is below 0 *C, bit 1 in parameter 0/9 will be
set (Freezing hazard).
The two values in parameter 0/D use 2:s complement representation, see section
“Internal Temperature Offset” for a brief description.

Relay Output (Y04-1)
Bit 1 in parameter 0/8 controls the relay in Y04-1. When the bit is set, the relay
switch is open, and when it is zero the relay is closed. Bit 1 in parameter 0/A is a
user flag bit that enables control of the relay function by the firmware. If this bit is
set the internal firmware will use the relay to warn of a freezing hazard (when bit
1 in parameter 9 is set) by clearing bit 1 in parameter 8.
When bit 1 in parameter 0/A is set and a PLC program tries to use the relay, the
firmware and the PLC will compete for control of the relay. Care should be taken
to only enable firmware control of the relay when no PLC program is using the
relay.
Parameter 0/8: (0/0/0/0/16)
