5.13 S7-200 (PPI - ISOTCP)<br />
5.13.1 Introduction<br />
General Reference Guide IO Servers Configuration<br />
The S7200 IO Server is dedicated to communicate directly with SIEMENS PLC of family S7-200.<br />
The <strong>eWON</strong> will connect directly to the PLC’s PPI interface.<br />
Since firmware 5.5, <strong>eWON</strong>s with an MPI port are able to communicate on a PPI MultiMaster bus.<br />
Then, to communicate with a S7-200 device you could use either an <strong>eWON</strong> with a serial port or an <strong>eWON</strong> with an MPI port.<br />
The <strong>eWON</strong> acts always as MASTER.<br />
The standard serial port of <strong>eWON</strong> must be configure in RS-485 (with dipswitch) to communicate in PPI.<br />
The ISOTCP (Ethernet) is available on all the <strong>eWON</strong> types.<br />
