5.12 S7-300&400 (MPI/Profibus - ISOTCP)<br />
5.12.1 Introduction<br />
S73&400 IO Server is dedicated to communicate directly with SIEMENS PLC (S7-300 & S7-400).<br />
The <strong>eWON</strong> will connect directly to the PLC’s MPI interface or Profibus DP interface.<br />
General Reference Guide IO Servers Configuration<br />
WARNING: The MPI/Profibus interface requires a special serial port hardware!<br />
ONLY the <strong>eWON</strong>s MPI/Profibus are able to communicate in MPI/Profibus<br />
<strong>eWON</strong> product codes like EWxxx6x (i.e.: EW41264 <strong>eWON</strong>4001 MPI with pstn modem)<br />
<strong>eWON</strong>s MPI/Profibus have a Serial Gender-Changer fixed on DB9 connector to provide female DB9<br />
connector.<br />
<strong>eWON</strong>s MPI/Profibus have a coloured (in light blue) square around DB9 connector labelized MPI (see photo<br />
on right).<br />
Others Serial IO Server (i.e.: PPI, modbus RTU) are not available on <strong>eWON</strong> MPI/Profibus.<br />
The ISOTCP (Ethernet) is available on all <strong>eWON</strong> types.<br />
With an <strong>eWON</strong>500 (with a standard Serial Port), you can have access to a S7-300&400 Siemens PLC by Ethernet thanks<br />
to the ISOTCP protocol.<br />
With an <strong>eWON</strong>500-MPI, you can have acces by the MPI port and by ISOTCP to your S7-300&400, if it has both interfaces.<br />
Multi-Session: Since firmware 5.4, the ISOTCP-MPI gateway allows multiple clients to access the same PLC at the same time.<br />
PPI MultiMaster (for S7-200): Since firmware 5.5, it is supported by the MPI port of the <strong>eWON</strong> (See “S7-200 (PPI - ISOTCP)” on page 130)<br />
5.12.2 Setup<br />
5.12.2.1 COM configuration<br />
Figure 96: MPI link configuration<br />
Parameter Description<br />
Gateway MPI/Profibus<br />
Destination Node<br />
Protocol Type<br />
Identifies the PLC MPI/Profibus Destination address when ISOTCP is used<br />
Select protocol MPI or PROFIBUS.<br />
As the MPI port configuration is shared by the S73&400 and the S7-200<br />
IOServers, this combo box shows also the PPI MULTIMASTER protocol (See<br />
“S7-200 (PPI - ISOTCP)” on page 130)<br />
PPI MultiMaster and MPI/Profibus are mutually exclusive. It is not allowed to<br />
use the S7-200 and the S73&400 IOServers on the MPI port at the same time<br />
.<br />
