In simulation and online mode, the AQs seem to be consistent with the PID output. Only AQ03 has an output voltage equal to the PID output. AQ01, and AQ02 has actual output voltages of 0Volts. Can any one help? PLC base module is Logo!8 230 RCE.

Are there compatibility issues with models of Logo main modules and expansion AM AQ modules? Could this be possibly the source of my problem?
