I have a project which need to connect between PLC5 and R1 controller.

Does anyone know the best way for this?
I don’t like DF1 as it’s too low.

The existing PLC5 has ethernet connection.

Re: Communication between R1 controller and PLC5

nvl,

You may have another option.

PAC Controllers running firmware 8.3 or later include EtherNet/IP functionality. EtherNet/IP is a common protocol A-B uses to communicate between PLCs, remote I/O and 3rd party devices. I have seen this web page http://www.ab.com/programmablecontrol/plc/plcsystem/index.html. You may be able to borrow a 1785-ENET or PLC5 with EtherNet/IP to see if the system will communicate. You may find addtional information here: www.io4ab.com. We have tested our implementation with A-B’s Logix series of controllers such as a ControlLogix and CompactLogix systems.

Here are some useful links:

Dear Bryce,
Does PAC communication with AB(PLC5) as master with this EtherNet/IP ?can we config PLC5 as a remote I/O of PAC R1 ? Please help us solve that project !

Re: Communication between R1 controller and PLC5

Binh,

Our experience is currently with ControlLogix and CompactLogix PLCs. The PAC appears as a remote I/O of the ControlLogix or CompactLogix PLC. Our I/O unit is either configured as a “Generic Ethernet Module” when using implicit Messaging in RSLogix 5000 or as a “path” when using a MSG block for explicit messages.

You will need expertise on the PLC5 and the EtherNet/IP implementation for the specific PLC and Ethernet card. The logic for the PLC5 must be modified to make this work.

Please review the links I provided on the original post. You may find similarities between the software toolset for the PLC5 and RSLogix 5000, enough to figure out what needs to be implemented.

Also, locate an A-B consultant to fill in the details for the PLC5 as well.
