Interface Description

IGSS32 offers a TCP/IP interface for the MODBUS/TCP type PLC equipment. A standard Ethernet interface board in the PC together with standard Windows TCP/IP protocol stacks enables IGSS32 to communicate with CPUs using the Open Modbus/tcp specification.

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.
