6.4 NETMPI IO Server
6.4.1 Introduction
NETMPI IO server is used to communicate with SIEMENS PLC. The eWON will connect to the PLC’s MPI interface by mean
of the eLINK adapter.
The eLINK adapter is an interface with an MPI interface on one side and an Ethernet TCP/IP interface on the other side.
The eLINK interface will be configured with an IP that the eWON will use to poll data. In addition to the IP address,
the eWON will need the MPI address of the PLC on the MPI bus.
Using that eLINK interface, it is possible to poll different types of item in the PLC. These items types are described below.
