Siemens S7 PPI adapter interface driver ID:58

Interface Description

The IGSS32 PPI Adapter communication interface offers connection to SIMATIC S7/200 PLCs using a SIMATIC S7 PPI Adapter and a standard serial RS232 port. The SIMATIC S7 PPI Adapter connects directly to the CPU port on the PLC using PPI protocol. On the PC side the PPI Adapter connects to a standard serial RS232 port.

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.
