Hello guys,

I have a problem in a modbus tcp communication between a scale and a cpu s7-1500. The block has status 7006 receiving data, but does not end with the received data. Communication with a software any modbus client works. Could there be a parameterization error?

 Although the request is false in the image, it was only at the time of the printscreen. he has a clock

Are you capturing the error status value if / when the error output goes true?  A simple check if error output true (NO) and a MOVE block to copy the error status value to another tag where the last error value can be read later works very well.

I like having a counter that increments on done and error so I can see if I'm getting errors, successes, or simply hung as busy or doing nothing.

Why did you set the local port to 0?  Because it was the default value?  Just curious.

 I just followed what the instructions said.
