Hello,
I am trying to setup a communication to a controller at my home.
The controller has setpoints that i can read with read input register
If i want to change the setpoint i have to send a write multiple registers.
Unfortunatly when i use a read input register on a slider it does not send anyhing, but it reads the value of the setpoint correctly.
When i use a read holding register on a slider it sets my setpoint correctly but the slider goes back to zero.

How to solve this?

Hello,

You can't write to input registers - they are designated as Anlog Inputs. Holding Registers are addressed for Analog Outputs so are read and write. If you are reading your value from input register and want to write value to holding register you should use other our product TeslaSCADA2. It lets you use different registers for input and output. TeslaModbusSCADA doesn't let you to do so.

Best regards,
Ruslan
