Structure of key bits in the peripheral input of the process data area
In the peripheral input key field 1 you will find information about the functional keys of the operator interface that have been pressed.
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 not that due to the cycle times there might be a delay in setting and resetting these bits.
- The combination (pressing) of several function keys at the same time is not supported. All key bits will be = 0 (zero) in that case.
- In the EasyProfibus no key bits are allocated to the key combinations Shift+F-key, ALT+F-key and CTRL+F-key.
- In the EasyProfibus no key bits are allocated to the soft keys .
