To achieve a defined byte order, you must always use 2-byte accesses
to implement the system parameters. Always select the access W
(word) when assigning the start-up variable number.
Poll Area
The polling area is used to manage the write coordination byte (WCB),
the serial message channel and the LEDs in the function keys. This
area is continuously polled by the operating device. The polling area is
structured as follows:
