and there is your problem.

you have specified the address to query in the PLC as `msg.topic`  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/d/8/d87ce213788c4616bc232101a3458c94d971ed26.png)

but you have not entered a PLC address in the inject...

Have you read the built in help?

It seems to me you are quite new to node-red (as that is a very basic skill) Perhaps you would benefit from first watching this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.

Hey Steve-Mcl

Thank for sharing you experince. I saw the playlist you showed me and I got me read command working Between the Plc and Node red. but i can't figure out to get my write command working. so i can write into my Global variables in my PLC.

do you have any advice about that problem, so i can find a solution

I am on my internship as PLC Engineer (In Denmark), and i having a school project where i try to develop a new HMI platform in node red dashboard. where i controll Omron LD 60 robot and some I/O.

according to the 2nd picture (shows `done` below the fins-write) you have managed to write to PLC.

What do you mean by "global variables" anyhow? Named variables? That is not possible with FINS protocol.

check your ladder. are you writing to W200 in ladder?

also, try setting the payload to an array (e.g. `msg.payload = [50]`)
