SQUARE-D Multidrop COM port protocol driver ID:60

Interface Description

IGSS32 offers an interface for the Square-D PLC equipment. The Square-D interface is designed to connect the IGSS32 system with one or more Square-D PLCs via the PC COM ports with a RS-232C TO RS-422 converter.

Point to Point connection are supported through a RS-232c/RS-422 converter directly to the CPU port on the PLC. It is also possible to address more PLCs on the SY/LINK network. Using the SY/LINK network requires the connected PLCs to be equipped with a network interface board.

The IGSS32 system polls the PLC equipment 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.
