nable:
If an ifm controller communicates with only one engine controller via J1939:
set ACE = FALSE.
If however several engine controllers are working on the same bus:
set ACE = TRUE.
In this case the engine controllers must support the address claiming!
Otherwise you will risk an overlapping of addresses with subsequent system failure.
