Interface Description
IGSS32 offers an interface for connecting to COMSAB II gateways. 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. The COMSAB II functions as a gateway, converting from the proprietary HDLC/RS485 protocol, which is used between the compressor control units, to a simple ASCII/RS232 protocol.
The IGSS32 system polls the compressor control units cyclically according to one of four user-defined time intervals. The time intervals are configurable from 100 milliseconds to 999 seconds. The system automatically groups process data in data blocks – thus fully exploiting the the communication link in relation to the present configuration.
