Modbus - AEROTEMPER - Fahd - 12.05.2023
Hi,
Attached you'll find a MODBUS RTU manual for an AEROTEMPER.
I did integrate a couple of Modbus devices before but the register list for this device is different from what I'm used to.
Can you advise on how I can determine the function of each register, whether it's a coil, discrete input, holding register, or input register? Additionally, can you provide information on the address of each register?
Thankful in advance

Holding register with uint16 data type. Use Read test to check that the values that you read are correct. You might need to do address - 1 for each register.

Provide your profile and check what you get in Modbus Error log.

What parameters did you use in Read test, it is not visible due to result.

Are you sure about the Error log? There's a log specific to Modbus, not global Error log.

Oups, this is the errors then

Map only the first register to an object and see if you get a reading.

I increased the pool interval to 20s and timeout to 5 also add read_delay to all the register by 0.1 . nothing helped
RE: Modbus - AEROTEMPER - admin - 21.06.2023
read_delay is a global setting: https://forum.logicmachine.net/showthread.php?tid=903&pid=13343#pid13343
