General Reference Guide IO Servers Configuration<br />
Figure 100: PPI link configuration<br />
Parameter Description<br />
COM Port Choose your COM port (only on <strong>eWON</strong>4002)<br />
Baud Rate Speed of the PPI port. Available speeds are 9600, 19200 Bauds or disable<br />
Parity The parity to apply (None / Even /Odd)<br />
Databits Number of bits in data (7 or 8)<br />
Stop bit(s) Number of Stop bits (1 or 2)<br />
HW mode<br />
Choose the Hardware mode of communication: Half-Duplex by default<br />
or Full Duplex with/without hardware handshaking.<br />
Reply Timeout Maximum time the <strong>eWON</strong> will wait for a valid PPI message response<br />
PPI Address Device address of <strong>eWON</strong> on PPI link (0..126, default is 0)<br />
Figure 101: MPI link configuration<br />
Parameter Description<br />
Protocol Type<br />
Baud Rate<br />
Select protocol PPI MULTIMASTER.<br />
As the MPI port configuration is shared by the S7-200 and the S73&400<br />
IOServers, this combo box shows also the MPI & Profibus protocols.<br />
PPI MultiMaster and MPI/Profibus are mutually exclusive. It is not allowed to<br />
use at the same time the S7-200 and the S73&400 IOServers on the MPI<br />
port.<br />
Speed of the MPI port.<br />
Available speeds are:<br />
• disable<br />
• 9.6 kBauds<br />
• 19.2 kBauds<br />
• 45.45 kBauds<br />
• 93.75 kBauds<br />
• 187.5 kBauds<br />
• 1.5 MBauds<br />
• 3 MBauds (only for 2005CD-MPI or 4005CD-MPI)<br />
• 6 MBauds (only for 2005CD-MPI or 4005CD-MPI)<br />
• 12 MBauds (only for 2005CD-MPI or 4005CD-MPI)<br />
Reply Timeout The maximum time the <strong>eWON</strong> will wait for a valid MPI message response<br />
PPI MultiMaster Address The device address of <strong>eWON</strong> on PPI link (0..126, default is 0)<br />
PPI Highest Station Address<br />
The highest station address polled by <strong>eWON</strong>. Select between 15, 31, 63 or<br />
127.<br />
