Siemens S7 HMI Adapter (S7 protocol) ID:28
Interface Description
The IGSS32 HMI Adapter communication interface offers connection to SIMATIC S7/300 and S7/400 PLCs using a SIMATIC S7 HMI Adapter and a standard serial RS232 port. The SIMATIC S7 HMI Adapter connects directly to the CPU port on the PLC using MPI protocol. On the PC side the HMI 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.
