Interface Description
The IGSS32 NetLink Adapter communication interface offers connection to SIMATIC S7/300 and S7/400 PLCs using a NetLink Adapter from HelmHolz Gmbh. The Netlink adapter connects directly to the CPU port on the PLC using MPI protocol. On the PC side the Netlink adapter connects to a standard Ethernet interface card.
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.
