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 Uni-
sab 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 communi-
cation. Select No if this is not the case.
