5.13 S7-200 (PPI - ISOTCP)<br />

5.13.1 Introduction<br />

<strong>General</strong> <strong>Reference</strong> <strong>Guide</strong> IO Servers Configuration<br />

The S7200 IO Server is dedicated to communicate directly with SIEMENS PLC of family S7-200.<br />

Since firmware 5.7, all <strong>eWON</strong> types, with serial port or with MPI port, are able to communicate in both PPI modes (MonoMaster and<br />

MultiMaster).<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 />

Usually, the <strong>eWON</strong> will be connected 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 />

Since firmware 5.7, <strong>eWON</strong>s with a serial port are able to communicate on a PPI MultiMaster bus.<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 />
