Parameter Description
Protocol Type
Select protocol PPI MULTIMASTER.
As the MPI port configuration is shared by the S7-200 and the S73&400
IOServers, this combo box shows also the MPI & Profibus protocols.
PPI MultiMaster and MPI/Profibus are mutually exclusive. It is not allowed to
use at the same time the S7-200 and the S73&400 IOServers on the MPI
port.
