Set the TCP/IP mode of the MA 208i.
In TCP client mode, the MA

In this case, the MA
With a MA
• IP address of the TCP server (normally the PLC/host computer)
• Port number of the TCP server
• Optional: Timeout for the wait time for an answer from the server
• Optional: Repetition time for renewed communication attempt following a timeout
In TCP server mode, the primary host system (PC / PLC) actively establishes the connec-
tion and the connected MA
requires information from the user regarding the local port of the MA
which the connection requests of a client application (host system) are to be accepted. If
there is a connection request and a connection is established by the primary host system
(PC / PLC as client), the MA
