I have an IRC5 with the Ethernet IP Master option. I need an AB Contrologix L61 to be the slave (I eventually will have several L61’s as slaves). After missing a bit of hardware, an incorrect keystring and an out of date baseware version I think I’m pretty close to achieving connectivity. What I am totally confused about is the Assembly Instance at the IRC5 end and the Contrologix end.
I too am having issues with this same thing. Does anyone at ABB have some examples of how to get Ethernet/IP communicating with any AB PLC’s?
I’m still trying different configurations such as setting up the robot as an IP_INTERNAL_SLAVE, and trying to make the PLC the master but not sure how to configure the PLC to communicate this way.
Any help or documentation would be greatly appreciated.
The Rockwell ControlLogix PLC:s don’t have the functionallity needed to be able to be connected as a server (internal slave) from another client (master).
To be able to contact the EtherNet/IP internal slave in the IRC5 controller from a PLC it must be configured as a EN_INTERNAL_SLAVE and for example 8 byte in and 8 byte out.
In module proporties for the IRC5 internal slave in RSLogix specify the correct IP address, assembly instances (input: 100 with size: 4 and output: 112 with size 4 and Configuration: 1 with size 0).
Use the Comm Format (communication format): Data - INT
Download and go online and the PLC should have established a connection to the IRC5 internal slave.
