Question:
Why do the analogue or digital hardware inputs in the system blocks of the control configuration in Servo-PLC or Drive-PLC not indicate the input value proportional to the voltage applied, despite the fact that the program is running.
Answer:
All the inputs entered in the control configuration only supply the correct indication value if the appropriate system variables of the system blocks are being used in a POE. Otherwise the necessary process image will not be generated for those inputs and the inputs will not be read in by the program. Instead of the system variables a new variable can also be created in the program and used which possesses the address of the hardware inputs.
