Interface Description
The IGSS32 Omron SYSMAC Way communication interface offers connection to all Omron PLCs supporting the SYSMAC Way protocol. SYSMAC Way is a serial protocol developed by Omron Electronics providing communication facilities for Omron’s C-series of PLCs. It is an asynchronous protocol which provides an interface for both single-link and multi-link systems by means of Omron Host link Units.
The communication interface supports both direct and dialled-up connections.
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.
