The IGSS32 SAIA S-BUS communication interface offers connection to all Saia PLCs supporting the S-BUS protocol. The SAIA S-BUS protocol can be used in both direct point-to-point and multidrop configurations. It can also be used in dialled-up applications using leased lines or public tele-network. The coommunication driver uses an industri standard RS232-C serial interface on the PC and supports all three SAIA S-BUS communication modes: parity, break and data mode.

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.
