SattControl Comli 31 ID:13

Interface Description

The IGSS32 Comli 31 communication interface offers connection to a large number of PLCs supporting the Comli 31 protocol e.g. SattControl’s SattCon range of PLCs. Comli 31 is a serial Master/Slave protocol which can run in point-to-point, star or multi-drop network configurations.

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 communication link in relation to the present configuration.
