I am using an ethernet/ip slave device of SMC.  
I have performed implicit and explicit messaging on it using MOLEX Ethernet/ip tool.  
Are there any nodes in Node-Red which i can use to perform the same via Node-Red ???

I'm not an "industrial" guy - but did you try searching the flows library for eip ? [Library - Node-RED](https://flows.nodered.org/search?term=eip)

Hello  
I searched the flows library but was unable to find one that uses explicit messaging.  
I want to access the device by using its class, instance and attributes.

If you can not find a node that does what you want you can  
1 - code one yourself (or find someone who will code one for you)  
2 - find a different way to get the data - (maybe use the exec node)  
3 - maybe code a program to access the data then call it via an exec node and pass NR the results

That’s all I can think of right now, others may have other ideas.

Did you try out [node-red-contrib-cip-ethernet-ip (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-cip-ethernet-ip) or the newer fork [node-red-contrib-cip-st-ethernet-ip (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-cip-st-ethernet-ip) ?

Yes Steve

These nodes give me the access of PLC's memory map but not in the way i want.

I think i have to create custom nodes.
