Instruction Manual
COMSAB II Computerized Control System for refrigerating compressors
Version 1.06
0178-444--ENG
1
Preface The present instruction manual, that covers the COMSAB II gateway, describes how to install the unit and how to use the SABROE protocol 0178-400. COMSAB II gives the user access to read and write data in the following SABROE compressor control units: PROSAB II, UNISAB S/R/RT/RTH and UNISAB II.
COMSAB II vers. 1.06 additionally gives the user access to read and write data in the Sabroe Chiller Control Unit. The COMSAB II functions as a gateway, converting from the proprietary HDLC/RS485 protocol, which is used between the compressor control units, to a very simple ascii/ RS232 protocol (0178-400) which is described in this manual. This manual refers to COMSAB software version 1.06.

Protective ground potential should best be the same for UNISAB and COMSAB as well as for any PCs or PLCs connected to it. A eavy gauge wire (6 mm2) running along with the communications tables from one protective ground to the next, may prevent a lot of trouble. Please observe local safety regulations which may not allow this.

Diodes: There are 4 diodes on COMSAB II, with the following function: Yellow ª (Idle) -- Light when net activity on port 1 (RS485). Green ª (Frame err.) -- Light when COMSAB II has synchronized itself to the baud rate on the net (RS485). Red ª (Overfl.) -- Light when COMSAB II is master. Yellow ª= (Power) -- Light when power is on.

Protocol: SABROE protocol 0178-400 describes the data communication between a central computer (PLC or PC), and a COMSAB II module. This protocol allows any type of computer (when above hardware is available) to retrieve data from a UNISAB or a PROSAB control panel, through the COMSAB II module. The protocol always waits to get polled by the central computer. It never starts a communication by it self. The communication is based on the central computer sending a telegram (a message) to the COMSAB II module. The telegram should always consist of a total of 11 (ascii) characters, that is 9 message characters plus 2 control characters STX (Start of TeXt) and ETX (End of TeXt).
Index
The value must be 20H [¬] = UNISAB/PROSAB # 1. The value must be 21H [!] = UNISAB/PROSAB # 2. The value must be 2EH [.] = UNISAB/PROSAB # 14. Point
Data field The Data field contains always 6 characters. The Data field can contain any integer value from --990 to + 99999. The value must be right justified. Not used characters must be space filled.
Message format:
The value in the Data field may be multiplied by a factor of 10. See Data format/Range in Read table and/or Write table.
Stx - Code - Index - Point - Data--field - Etx Starts the telegram (1 character). Stx = 02H [ ^B] Code
Indicates read/write telegram (1 character). The value should be 20H [¬] when reading data. The value should be 21H [!] when writing data. The value should be 22H [”] when reading COP data from UNISAB II.
0178-444--ENG
Indicates the address of the variable which should be read or changed (1 character). The value must be 20H-FFH according to the table 0178-402.
(The corresponding ASCII character is shown in sharp parenthesis, where [¬] means an ASCII ’space’)
Stx
Indicates the dialing # of the UNISAB/PROSAB which must receive this telegram (1 character).
Etx
Ends the telegram (1 character). Etx= 03H [^C]
Reply from the COMSAB II: When writing data by a COMSAB II, the reply message is a copy of the message sent to the COMSAB II. Data written to UNISAB II is checked in the UNISAB II. If the value exceeds the limits that are built into UNISAB II (see UNISAB II
7
instruction book for reference) then UNISAB II accepts and returns the lowest or highest of the built-in limits, depending on which limit is exceeded. Data written to UNISAB I or PROSAB II is checked in the COMSAB II. If the value exceeds the limits that are build into COMSAB II, then COMSAB II returns an error message with code F____6. For reference -- see the limits table under note (5), placed under notes following the table Points to Write. When reading data by a COMSAB II, the reply message is a copy of the message sent to the COMSAB II, except from the Data field which will be filled with the value asked for. Depending on the data type then the value returned may be in 1/10 of the unit asked for, i.e. +/-- xx.x BAR, +/-- xxx.x ’C, xxx.x % etc, se Data format/Range for the specific point asked for.
If a parity error occurs, or the number of characters received in a message by the COMSAB II is different from 11, no reply will be given to the central computer.
Tables: In the table 0178-402 /Read and Write, details about selecting the correct point, details about translating the reply for compressor control mode etc are given.
Response time: There is always a time delay from the moment a change in e.g. pressure on the compressure unit is seen until it actually can be read by the COMSAB II module. The worst case time delay can approximately be calculated with this equation: TimeDelay = 13 + ( 1,5 * N ) seconds at 1200 Baud. TimeDelay = 7 + ( 0,8 * N ) seconds at 2400 Baud.
Possible error messages:
TimeDelay = 1 + ( 0,1 * N ) seconds at 19200 Baud.
This protocol gives an error message if the communication fails. The error message is given in the Data field:
N is the number of compressors connected to this COMSAB II module.
Data field:
_____
No error ( 6 spaces ).
Data field:
F___3
Code does not exist.
Data field:
F___4
Index does not exist.
Data field:
F___5
Point does not exist.
Data field:
F___6
Read/write not possible.
Another delay occurs in the communication between the COMSAB II and the central computer. This delay depends on the sequence of communications from the central computer to the COMSAB II. (As worst case). At worst, this time delay must be added to the time delay calculated above.
Data field:
F___7
UNISAB/PROSAB does not exist.
Examples:
Data field:
F___8
No such control system.
Data field:
F___9
Syntax error in message received.

Note the following: X:
Read point 52. If there isn’t any alarm in the UNISAB II then the reply will be a 0 (zero). If there is one (or more) alarms in the UNISAB II then reply will be the number of the oldest alarm, i.e. a alarm number from 31 to 76 - see the table of alarm/warnings. Too see if there are more than one alarm in the queue, then send a read message reading point 53, then point 54, 55 and 56, until the reply from the COMSAB II is a 0 (zero).
Valid for this control system: PII/UI = PROSAB II and UNISAB S/ R/ RT/ RTH. UII = UNISAB II.
(X):
Not used for normal control purpose.
Range: I = Integer, ie. data range -- 32268 -- + 32267 UI= Unsigned integer, ie.data range 0 -- 65535 I*0,1 = Integer value in 1/10 of the unit for this point. I.e. for point 32 ”suction gas temp.” this means that a read value of 325 is 32,5°C. B = Byte, ie. data range -- 128 -- + 127 or 0 -- 255. (1):
Only when hardware option available.
(2):
See ”TABLE OF COMPRESSOR CONTROL MODES”.
(3):
See ”TABLE OF COMPRESSOR MODES”.
(4):
See ”TABLE OF ALARM/ WARNINGS”. In the UNISAB II all alarms, i.e. a alarm number, are stored in an alarm-queue, containing max. 5 alarms. The first (oldest) alarm are stored in ”alarm1” (read point 52), the next alarm in ”alarm 2” (read point 53) and the last (newest) alarm are stored in ”alarm 5” (read point 56) - see read table. To read the UNISAB II alarm-queue you will have to do the following:
20
The same procedure is used when reading the warnings-que. (5):
See ”TABLE OF CONTROL SYSTEMS”.
(6):
See ”TABLE OF MULTISAB STATES”.
(7):
Only PROSAB II and UNISAB S. For UNISAB S this is a calculated value. Not a measured value.
(8):
Only PROSAB II, UNISAB S and UNISAB R.
(9):
Not UNISAB R.
(10):
Running hours are read as hours x 1.
(11):
Run time since last start are read in sec.
(12):
Not implemented.
(13):
Only UNISAB II. See notes for capacity control
(s):
Only screw compressors.
(r):
Only reciprocating compressors.

Capacity Control (communication) It is possible directly to control the capacity of the compressor by sending a capacity setpoint by communication. For UNISAB II it is possible to control the capacity on both screw compressors and reciprocating compressors. For PROSAB II and UNISAB S it is only possible to control the capacity on screw compressors. UNISAB II must be set to REMOTE in picture CONTROL. PROSAB II and UNISAB must be set to REMOTE mode by using the SET button. Screw compressors (when running) will directly follow the capacity value (0--100%) whitch is specified in ”Setpoint for capacity”, point 52 (remember the setpoint is in 1/10 of percent). Notice, however, that the various limiting functions may reduce the compressor capacity. Reciprocating compressors will shift one capacity stage up or down, depending on whether the value specified in ”Setpoint for capacity”, point 52, is above or below the percentage value that correspondes to the capacity stage in question.
26
The timers DELAY UP and DELAY DOWN will be in function if the UNISAB II program version is 1.08 or later. Notice, however, that the various limiting functions may reduce the compressor capacity. When a capacity setpoint is sent to UNISAB II, UNISAB S or PROSAB II it will enter the capacity regulation mode, this can be seen by the fact that the start number is set to zero (the ”old” start number is remembered, UNISAB II stores the number itself and for UNISAB S/ PROSAB II the number is stored in PCCOMSAB II) . UNISAB II, UNISAB S or PROSAB are taken out of capacity regulation mode by sending a new setpoint 1 or 2, neutral zone (NZ) or proportional band (PB) value to one of the other regulators, e.g. suction regulator, brine regulator etc. When UNISAB / PROSAB II are taken out of capacity regulation mode the old start number is reinserted. It is possible to take UNISAB II out of capacity regulation mode by changing START NO back to the old start number on the UNISAB II display. In that case you must reset COMSAB II. This is done by making a power off/ on. Read point 125 ”Cap. mode” will be ”1” if UNISAB II is in capacity regulation mode, else ”Cap mode” will be ”0”.

Start:
Stop:
The compressor can be started in two ways (situation 2 is only possible for UNISAB II)
The compressor can be stopped in two ways (situation 2 is only possible for UNISAB II)
1. By sending the start command ”START COMPRESSOR”, point 53. 2. When the capacity setpoint sent is above 5 % and AUTO START = YES has been configured, the timer START DELAY begins to count down in case of screw compressors. For reciprocating compressors the timer START DELAY starts once the signal is above the lowest capacity stage, i.e. above 25%, 33% or 50%, depending on type. When the timer START DELAY has counted down, the compressor starts and will now follow the setpoint up/down.
0178-444--ENG
1. By sending the stop command ”STOP COMPRESSOR”, point 54 2. When the capacity setpoint sent is below 5 % and AUTO STOP = YES has been configured, the timer STOP DELAY begins to count down in case of screw compressors. For reciprocating compressors the timer STOP DELAY starts once the signal is below the lowest capacity stage, ie below 25%, 33% or 50% depending on type, however, for reciprocating compressors with total unloading, the timer STOP DELAY starts counting down, once the signal is below 0%. When the timer STOP DELAY has counted down, the compressor will stop.

List of Versions Version 1.00 Error when reading motor current and hour counter from Unisab I and Prosab II. Limiting values for external input extended. Version 1.03 Error when reading SP1 and SP2 for brine temperature when ClimateControl has been chosen in Unisab II and when the brine temperature is being regulated. Version 1.04 No errors. Must be upgraded to include COP and chiller data. Version 1.05 We have corrected an error which made the Unisab II change start number to # 0 and at the same time change the control mode to auto. The change was automatically carried out by Unisab II, whenever the direct 4-20 mA capacity signal was connected or disconnected. Version 1.06 The Comsab II now recognizes a Unisab II configurated as a Rotatune controller. In earlier versions it was not possible to see any of the values in the Unisab II if the answer to the parameter Rotatune=(YES/NO) in the Unisab II menu was YES: Main picture > main menu > setup > config > Motor > Rotatune In spite of this problem, the Comsab II was still able to read the values from the other Unisab II in the system (with Rotatune=NO). In the manual the table of alarms/warnings for Unisab II has been updated to comply with the eprom version 2.03.1. Also the list of multisab states has been updated to comply with the eprom version 2.03.1.
