I am by no means a messaging expert. I know SLC to SLC and CLX to SLC, but that’s about it’. No experience with the SLC EEM instruction.
I was sent a OneFex remote unit, 4 DI, 4 Relay-DO, 4 AI. They say it’s RTU over Ethernet, and I have it setup with their software - I can see the inputs on & off and the analog values, and turn the outputs on & off with their software over the network.
The first thing I would like to do is see if I can message this with a SLC5/05 to add to a machine, but haven’t been successful in getting it to be seen with my home 5/05 Ser E. Again: “No experience with the SLC EEM instruction.”
Do any of you with great messaging experience see how in the manual below to have a SLC see this, or if not possible how would a CLX see it so I can use it for something else.
The thing looks good quality and for the price it might turn out to be a deal - if they work. I don’t want resort to using the DH-485 port and run serial cables.
The module’s TCP protocol defaults to Modbus TCP, but it can also support Modbus
RTU over TCP, just select “Modbus Gateway” to OFF. That is, when ON is selected, it
is Modbus TCP protocol, and when OFF is selected, it is Modbus RTU over TCP
protocol.
But that seems to be for the DH-485 port, maybe the Ethernet port too??
I don’t know if it’s ETH or ETH/IP.
The only thing their saleslady said was these work with Allen-Bradley.
Browsed the manual, watched a couple of YouTube videos.
I do not think this will work with a SLC.
There looks to be an EDS file available, so you can use it with a CLX. The youtube video was very blurry, and difficult to follow the selections exactly.
A ML1400 should also work via Modbus TCP.
I guess you could use the Rockwell AOI, for Modbus on the CLX too. But I never liked that solution. Resource heavy, and not as reliable as I would like.
