thanks for fast replying

[Steve-Mcl]

and there is your problem.

you have specified the address to query in the PLC as msg.topic

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. 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

picture of my current setup

Note about project.
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.

@Marcus_andersen

but i can't figure out to get my write command working. so i can write into my Global variables in my PLC

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.

[Marcus_andersen]

I can see what you mean, but the value dosen't go into my watch & tab table, at sysmac

So i am not shure about, the value look at the picture below

How can I figure out that problem?

global variables I mean it just where i have my Outgoing variable in My plc program

[Steve-Mcl]

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

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