* If you enable diagnostics for multiple channels, you will receive an alarm surge on failure of the supply voltage because
each enabled channel will detect this fault.
You can prevent this alarm surge by enabling diagnostics for one channel only.
** The scope can be assigned for each channel during parameter assignment in RUN.
*** For the configuration as a 4 x 8-channel module, a maximum of 16 hardware interrupts can be configured (channels 0 to
15).
