2.1 Ethernet
The Procon MOD-IP/50 is a 10Base-T half duplex device and needs
to be connected to the G-50 and the local network (if Modbus/TCP is
being used). Fig.1b shows the use of a hub / switch ( not supplied ) to
make the connections, but the Procon unit and the G-50 could just as
easily be connected directly to the network.
See Appendix C for port configuration.
Note: a) The Procon MOD-IP/50 and the G-50 require separate
IP addresses which must be on the same subnet.
b) The MOD-IP/50 does not support Auto-Negotiation.
