TComm Serial protocol driver ID:67

Interface Description

IGSS32 offers an interface for the Techno Trade Modbus Communication Driver. The driver support the master protocol that can be used in both point-to-point and in multidrop configurations. The IGSS32 driver implements direct point-to-point, dialled-up and radio connections to PLC’s.

The communication interface is also capable of reading historical sampled data in TBOX PLC, thus making it possible to make reports and show graphs of signals stored in the TBOX even though it is not directly connected all the time (e.g. in dialled-up configurations).

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.
