Ethernet PLC
PG/PC-interface for Ethernet-PLCs
In order to reach an Ethernet PLC via a VPN connection,
activate and correctly complete the option “Use router”
in the Ethernet interface of the PLC to be used for re-
mote management. The IP address to be entered under
“Address” must correspond to the LAN IP address of
the REX300. The IP address of the PLC must be in the
address range (subnet) of the REX 300 LAN interface.

In order to reach the PLC via the VPN, just select the
corresponding interface. This should be chosen such
that TCP/IP on the interface shows which serves as the
Internet access. For laptops e.g. “TCP/IP -> Intel WiFi
Link”.
Note:
If the PLC is to be connected directly to the REX 300,
these must be inter-connected using the Ethernet cable
(crossover) enclosed.
If the REX 300 is connected to an Ethernet switch then
either a straight-through or crossover cable can be used.
As soon as a VPN-connection to the REX 300 has been
established, the PLC from the project can be worked on
(e.g. hardware download, monitor variables etc.).
Note:
The PN IO-directory of Ethernet PLCs is not
displayed via the reachable participants.
