Hello Community,
I was hoping that you could help me set up the SE modbus write block for node red. I have not found a way to join all the values and send them as a complete package to the PLC. I used the JOIN function, but the values were moving from registers to registers like a cycle. I had to use a lot of the SEModbus write blocks individually to get it to work in conjunction with delays so the communication doesn't crash.
I'm adding the image, maybe someone can help me make a little bit smaller.
Thanks to all.

Hello Kevin,
You want to write values in continous registers of the PLC via FC16?
In my opinion you need to put them in an array. But I did not try it.
But did you know the manual to the nodes which you could find Link Node Manual
Maybe this could help you.
best regards

I'd love to help out (and at the same time try the SE nodes for modbus communication), however I'm not able to either complete the offline (no access to file on box) or online (can't resolve npm registry hostname) installation procedures.

Hello,
Already try to put them in an array or a join function, but for some reason, the values keep moving from register to register, but If I do it individually, I have no problem at all.

Hi,
It seems you need to get it from Schneider, but I can share it with you. Will you give me your email?

I already reached out to my SE contact for the files.
Thanks for the offer!

Hello Tom,
Just sent you the install.
At the moment the install as mentioned in the manual is not available. In future the download should be possible from Exchange (as promised by the offer manager).
