ifm function elements ifm function elements for the device CR0431
J1939_ENABLE
7641
Unit type = function block (FB)
Unit is contained in the library ifm_J1939_NT_Vxxyyzz.LIB
Symbol in CODESYS:
>
Description
7642
For initialisation of the J1939 stack, J1939_ENABLE is set to TRUE=1.
>
This FB also causes booting of the soft I/Os of the CFG file.
>
A different baud rate is only adopted if CAN_ENABLE has not been activated before.
ACE = A ddress C laiming E 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.
