Set-up
6.4.6 Communication
The Communication menu includes set-up for Danbuss and Profibus communication.
1: Compr. 1 to 14
This compressor number must be entered into UniSAB III. The compressor has then been "named".
Two compressors must
never have the same number.
2: Baud rate
1200
2400
4800
9600
19200
This is the communication speed used for Danbuss (Sequence) communication between UniSAB III
units and possible UniSAB II units.
UniSAB III allows a communication speed of up to 19,200 baud. If UniSAB III is connected with UniSAB
II, adjust speed to 19,200 or 9,600 baud. UniSAB II versions manufactured from May 1998 supplied with
revision G relay prints (where relay no. 7 is mounted in a socket) allows a communication speed of up to
19,200 baud. For older UniSAB II units, the maximum speed is 9600 baud. Normally, always select the
highest baud rate that all units on the network can use.
3: Danbuss master enable
Yes
No
Normally select
Yes which is the normal Danbuss configuration.
Only select No if the Danbuss sequencing network includes RCM controllers.
Note: This is a special setting which disables some Danbuss Master functions. These functions must be
switched off in UniSAB III in order to comply with the RCM controller used in some old marine
installations.
4: Profibus
Yes
No
Select
Yes if UniSAB III should communicate with a PLC or other device via Profibus communication.
Select No if this is not the case.
