Status code
General rule to generate status information in AS
for all AI signals:
Signal is disturbed if value >= 32512 or value<= -32512

For 2 wire calibration of module TIM R 9480/.. and TIM 9482/.. the user interface (LCD display with buttons)
of the CPM 9440 has to be used.
Automatic 2 wire calibration of derTIM modules by short circuit at the end of the line can be used in
combination with 9442 CPUs. Details see the operating instructions of the TIM modules.
