Description
15426
As from runtime system V03.00.03 the CAN stack automatically sends a DM1 message every second
as soon as the FB J1939_ENABLE (→ page 138) is called for the corresponding CAN interface.
► Use the FB J1939_DM1TX_CFG if you do not want the CAN stack to automatically and cyclically
transmit DM1 messages.
The FB offers the following modes for cyclic transmission of DM1 messages:
MODE = 0
(preset)
The CAN stack sends DM1 "zero active faults" messages in compliance with standards every second.
A manual transmission of DM1 messages via the FB J1939_DM1TX (→ page 163)is possible.
MODE = 1 The CAN stack does not send DM1 "zero active faults" messages.
DM2 requests are answered automatically.
A manual transmission of DM1 messages via the FBJ1939_DM1TX (→ page 163) is possible.
MODE = 2 The CAN stack does not send cyclic DM1 "zero active faults" messages
Nor does the CAN stack automatically reply to DM2 requests.
