PC accesses MELSECNET via Ethernet

In this combination a PLC is connected to the PC via ethernet. The PC must therefore know the IP

address of the E71 board in the PLC rack. Connection to the E71 can be tested with the 'ping

<n>.<n>.<n>.<n>' command, where the parameter is the IP address, which has been set in the

network parameters using either GX Developer or GX IEC Developer.

The relaying PLC contains a MELSECNET/H board, which is connected to another

MELSECNET/H interface in the target PLC, which also holds the PROFIBUS board. For this

relaying the PC and the E71 in the PLC must be setup as a virtual MelsecNet, i.e. the E71 must

also be configured with a MelsecNet network and station address. The PC must have a station

address, which must not exist already in the same network number.

The network and station number of the MelsecNet board in the relaying PLC are not relevant for

the setup of the network path. The MelsecNet boards in both relay and target PLC must share the

same network number and have different station numbers.
