Easy ProfibusEPB Functional DescriptionProcess data areaPeripheral input key field 0

 

In the peripheral input key field 0 you will find information about the functional keys of the operator interface that have been pressed, as well as about other bit functions.

Each time a function key is pressed, the corresponding key bit is set and remains set for the entire time the function key remains pressed.

Please note that due to the cycle times there might be a delay in setting and resetting these bits.

Additional bit setting functions can/will be executed.
