Hi all,
I'm scripting a process to simulate power meters with luamodbus functions, and it works wery well when I read all my registers with ModbusPoll scanner.
But using my script with a real Modbus master product, I have a lot of "connexion errors" (printed by the master).
@IP, port and slaveId are corrects...
Any idea about this ?
Thank's in advance.
All my best.
Dominique

Consider using this script instead: https://forum.logicmachine.net/showthrea...6#pid27726
Your current script does a lot of busy polling via grp.getvalue after each slave step which can lead to timeouts.

It seemed to me that the problem was there. Thank you for this new version that I will try immediately.
Many thank's too for your help.
