4.4.1. Example of a reaction / command following a specific error

The following example enables commanding an alarm following an overload or short circuit on
the number 5 output of a ICMK 14 N1 remote unit with address 3 on the CS 31 bus. Another
output is also activated at the same time as the alarm in order to, for example, issue a cut the
actuators power command.
This is a class 4 type error and uses the following variables:
- M 255.14 : class 4 error presence bit
- MW 255.08 : the error code
- MW 255.09 : the unit type
- MW 255.10 : the unit address
- MW 255.11 : the defective channel number
