S7-200

The eWON S7200 IO Server is dedicated to communicate directly with SIEMENS PLC of family S7-200. The eWON will connect directly to the PLC’s PPI interface.

On a PPI Network, an eWON with Serial interface is monoMaster (eWON must be the only device acting as master on the network).

But since firmware 5.5, eWON with MPI port are able to communicate on a PPI MultiMaster bus.
