Communicating with DeviceNet from Another Network 5-9
Communicating with
DeviceNet from an Ethernet
Network
Before performing this example the Ethernet network must be
configured and running. A 1785-ENET module must be installed on
the PLC-5 processor and connected to the network.
See the PLC-5 Ethernet Interface Module User Manual (publication
1785-6.5.19) for more information.
Establishing Ethernet pass-through communications involves four
main steps:
1. You use RSLinx to configure the Ethernet to PLC-5 driver. This
procedure is described on pages 5-9 to 5-11.
2. You configure the 1785-ENET module’s communications channel
and download the configuration to the PLC-5 processor. This can
be done using RSLogix 5 software when you create the example
ladder program. The Ethernet channel configuration is described in
Appendix A.
3. You use RSLinx to configure the DeviceNet pass-through driver to
communicate with the 1771-SDN module via the Ethernet network.
This procedure is described on pages 5-12 to 5-15.
4. You use the pass-through driver with RSNetWorx for DeviceNet
software to adjust and tune your DeviceNet network. This
procedure is described on pages 5-15 to 5-17.
Configuring the Ethernet to PLC-5 Communications Driver
To communicate with your PLC-5 processor over an Ethernet network
you must configure the Ethernet to PLC-5 driver. Perform the
following steps to configure the driver using RSLinx software.
1. Start RSLinx .
