DCU-DFC-Host Interface
Interface Description Host ' Substation
1 GENERAL
The interface described below allows a data communication between a host computer and one of the
following devices:
DCU-System
FIS
EGAS
Biostat B
Biostat C
Biostat D
Micro-DCU
(Biostat B-DCU, Biostat C-DCU ect.)
DCU Hardware
(Fermentation Interface System)
FIS Hardware
(Exhaust Gas Analyzer System)
DFC Hardware
(Lab Fermenter 2,5,10 Ltr.)
DFC Hardware
(Lab Fermenter 10,15,20 Ltr.)
DFC Hardware
(Lab Fermenter 30 - 150 Ltr.)
DFC Hardware
(Control unit with external components) DFC Hardware
In the following these systems are named substation. There are different hardware platforms
(DCU,FIS,DFC) of the fermenter process control units. The functions of the Host-Interface depends on
the used hardware as well as the installed software version. In the appendix, there is an overview table
explaining the different functions of the Host-Interface for each control unit and the different software
versions.
After initialization of the Substation the Host can request data from the Substation wihtout restriction. The
Substation receives a telegramm which requests for data being sent to the Host within certain time limits.
The data have been specified during initialization.
Fermentation parameters can only be sent from Host to a Substation if the Substation has been released
for transmission. To achieve this, the functional key must be set to "Remote Mode".
The communication protocol is character oriented and the data are coded according to the 7-Bit-ASCIIcode (DIN 66003,international characters).
The physical transmission medium comprises an asychronously working serial interface, whose driver
can be freely choosen in the Substation, depending on the mode of application.
The following interfaces can be choosen in the Substation:
- RS-232C
- RS-422
- Ethernet 10-Base-T (RJ-45)
at peripheral interface connector
at Host computer connector
at Ethernet computer connector
The common RS-232C interface is not as insensible to interfering signals as the RS-422 with
differential interface lines. Besides the RS-232C interface only allows point-to-point connections at
comparatively short distances.
The electrical properties of the RS-422 interface are designed for modern multidrop connections. They
comply with DIN 66259 T4 and ISO 8482 and derive from EIA RS-485. Further information can be found
in the corresponding standards and in the operators handbook for the Substation.
The electrical properties of the ethernet interface are designed for modern multidrop connections. They
comply with IEEE 802.3. Further information can be found in the corresponding standards and in the
operators handbook for the Substation.

2 PREREQUISITS FOR DATA TRANSMISSION
2.1
TRANSMISSION CONTROL VIA HOST COMPUTER
The data are transmitted between Host and Substation according to the master-slave principle, i.e., the
data transmission can only be started by the Host Computer. A communication between the Substations
themselves (multidrop connection) is not possible.
The host computer can control the data transmission to a Substation via commands. Commands are
available for:
DR
DS
SU
requests for process data from the subsystem
send process data to the subsystem
subsystem initialization
All commands are described in chapter 4 in detail.
A specific Substation is selected by an address field in the command telegramm. For each Substation
the address can be manually set.
2.2
SUBSTATION INITIALIZATION
Prior to the first data request the host computer must initialize the corresponding Substation (command
DR). The initialization command sends parameters to the Substation and thus adapts the data
transmission to the requirements.
The first parameter is a list of data groups which have to be transmitted to the host computer as
response to a data request command.
The second and third parameters are reserved for future applications. The field must be completed by
the following values:
Parameter 2: 5
Parameter 3: 2
Without initialization the Substation sends an error telegramm after receiving a data request command
(DR). For further details see chapter "Commands".

Interface Description Host ' Substation
2.3
BREAK-GENERATION VIA HOST SYSTEM (RS422, RS232 ONLY)
Before sending a command to the Substation a break condition must be generated on the interface in
order to switch the connected Substation to the "Receive" mode. The duration of the break (depends on
the baudrate) should be approximately the same as the transmission time for two characters. After
resetting the break a 2ms delay time is recommended before sending characters. In each case the
"Break" condition must be generated prior to each command to the Substation by the Host system.
2.4
REMOTE MODE
The Substation can be manually switched to the operating mode "Local" or "Remote" by means of the "
Remote" key of the DCU / Biostat B keypad. But only the "Remote" mode allows a control via the Host
Computer, i.e. only in the "Remote" mode the Substation accepts the set parameters of the Host System.
Except for the initialization command and the setting of the real time and the process time, all
commands with which parameters in the Substation can be changed will be responded by an error
telegramm if the Substation is not in the "Remote" mode.
If the host computer sets the process parameters in the "Remote" mode all other functions, direct access
included (Shut down, Acknowledge etc.) can be realized at any time.
A change from "Remote" to "Local" is only active (delay possible) when a running data
transmission/processing of one block is finished.
2.5
RESERVED CONTROL CHARACTER
The following characters are required for data transmission control.
*
-
-
Start character Host telegramm
# -
Start character Substation telegramm
:
Delimiter for data fields
-
@ -
End mark for each telegramm
/

2.7
Transmission formats for date and time
For transmission of date and time (DAT) as well as of process time (AGE) special formats have been
established. For separation of the integer fields specific control characters have been reserved. The
following formats have been defined:

2.7
TABLE NUMBERS
In the structure of the message field (see Telegram Format) exists a number field before each value.
These numbers are corresponding to the order in one of the following DCU-Table:
Process Display
Process Display
Process Display
Process Display
PVAL Table for process values
CLOOP
Table for controllers
DGIN Table for digital inputs
DGOUT
Table for digital outputs
These table numbers are shown in the DCU-menu " Process Display" and the corresponding table.
2.8
RANGE OF VALUES FOR DATA TRANSMISSION FIELDS
The range of values for the types of data used in the data field definitions are as follows:
-
Byte
Integer
Real
String
0 ... 255
0 ... 32767
-1000.0 ... +1000.0
<= 255 characters
The transmission of the process values with the mark "REAL" is standardized. The range of values has
been defined as 0 .. 100% = 0 .. +1000.0. The values for controller outputs as well dosing counters are
an exception. The range of controller output values is -100% .. +100% = -1000.0 .. +1000.0 . The range
for dosing counters are not limited in the DCU-System, so the value can be greater than 1000.0 (e.g.
4255.7).
2.9
RESPONSE TELEGRAMMS OF SUBSTATIONS
The contacted Substation responds within the Timeout limit (500ms) with the required reponse
telegramm (specification see below) or with an error telegramm if all the following conditions are given. If
one condition is not given none of the connected Substations will respond.
1. Command telgramm begins with * and ends with @
2. sent check sum = calculated check sum
3. received address = set address

2.10
TMEOUT AND REPETITION
In the case of transmission errors the host system can automatically repeat a command by means of
time out supervision and sequence counter. The number of repetitions is not limited and will be
determined by the Host system.
The time out conditions for a host computer are defined as follows:
The time out period begins when the last character has been sent from the host
computer.
The period is finished when the first character of the response telegramm has been
received. Thus the timeout supervision does not depend on the transmission time of a
complete response telegramm.
If no character has been received by the contacted Substation after 500 ms the
timeout condition is activated.
The Substations ensure that the reponse is not transmitted after the timeout period.
Refer to the following example for better understanding:
Host sends command *1:DR:0:0:569@ and receives error telegramm or no
character after the time out period of 500 ms.
Host sends the same command with incremented sequence *1:DR:1:0:570@ if the
maximum repetition number has not been exceeded.
The Substation stores the last sent response until the next command is received in order to be able to
repeat the data (incremented sequence) if necessary.
Note:
The transmission time for one character depends on the set baud rate. Thus the
transmission time for one character at low baud rates is comparatively long. The time
out period of 500 ms takes into account rates of 300 - 19200 Bauds.

2.11
END OF DATA TRANSMISSION
The data transmission is only finished if all data blocks (cf. 2.14, block transmission) of one Substation
telegramm are corretly sent to the Host.
A new reponse telegramm is only sent to the Substation if the last data block has been sent to the Host
and if the Host Computer has then sent a new data request command wiht the sequence 0.
2.12
DATA SECURITY
A correct asynchronous single byte transmission is ensured by means of checking the corresponding
error bit in the USART-element. Double parity errors in one byte are recognized by check sums.
2.13
CHECK SUM
The check sum is formed by addition of all ASCII values from the start sign (* or #) up to and including
the delimiter (:) directly in front of the check sum. The calculated value cannot exceed the value of 32385
and is variable, denpendent on the message length.
2.14
BLOCK TRANSMISSION
For extensive data transmission the Substation divides the data into several blocks. When receiving the
next data request command from the Host Computer (no incremented sequence) the next data block will
be sent. If the sequence of the data request command is enlarged the Substation sends again the last
data block to the Host Computer. In the last data block of the Substation response telegramm the status
bit d3 is reset to the inactive condition.
The blocks are divided in such a way that no complete data field (No../Value) is divided.

3 TRANSMISSION VOLUME AND DEFINITION OF DATA FIELDS
Due to extensive data quantities in the Substation the process data are divided into different data groups.
For identification of the data groups in the serial data flow each group has a defined designation. Even if
the data group is transmitted in two blocks, each block is designated in such a way. Each process value
also has its defined identification with a number from the corresponding Substation table.

The status field always indicates the actual status of the sender. Between host and Substation, however,
different function assignments exist. The status field in the reponse telegramm always has the structure
given below. The status definition of the host must not be taken into account here. It is reserved for
future applications. The field, however , must be filled with the defined value of 0.

OPERATING MODES
HOST Ù SUBSYSTEM
For synchronization of the real time clocks of the Host Computer and the Substation, the Host can adjust
the time of the Substation. Additionally the running process time of the Host can be adjusted. Both
adjustments are possible in the "Remote" and in the "Local" mode. Inside the DCU there is a connection
between realtime and process time, and is is not possible to send both times together in one command
to the DCU. Therefore you have to use two different commands.

4 COMMANDS
In order to achieve a defined data flow between Host and Substation several commands from host to
Substation are necessary. Each command of the host is responded by the Substation if the sending
conditions are given (2.9 Response telegramm of Substations). The Substation sends an
acknowledgment or error telegramm after the commands SU and DS and after the command DR the
Substation sends the process data or an error telegramm to the host. The acknowledgement telegamms
have the following structure:
- Start character and address
- Reflexion of received command
- Reflexion of received sequence
- current statusfield
- Check sum and end mark
Examples for acknowledgement telegramms are at the end of each command description.
The Substation error telegramms are described in chapter 5.

TRANSMISSION OF PROCESS DATA
HOST Ö SUBSYSTEM
This command allows the data transmission from host to Substation ( if the Substation is in the Remote
mode). All process data with the specified transmission direction Host -> DCU / FIS can be sent to the
Substation herewith. To achieve this the information field must be completed with the required
designations of the data groups and the process values (cf. examples). If the definitions of the separate
data fields are not observed the Substation sends an error telegramm and thus denies the process data.
Additionally the Substation checks the status of the REM key and sens an error telegramm if the key is
not activated. Only an activated REM key allows the data setting by the Host Computer.
The adjustment of the process time and real time (designation BC) is an exception and can only be sent
to the Substation at any time like the initialization command.
The data setting with the command DS does not depend on the initialized data group. Even controller
setpoints can be determined by the Host, despite the fact that no sepoints but only process values
should be sent from the Substation to the Host (only PV initialized).
Command:
- String
Designation,
Number,
Value
DS "Data Set"
Depending on the type of application,
the structure can differ
Example:
*1:DS:0:0:CS:3:625.0:CM:3:1:PA:3:0.0:666.6:1:0:0.0:2859@
