Evaluation of CAN NMT telegrams (remedied from V1.4)

Eliminated from:
EPM-T110 (CAN Gateway V1.4)
EPM-T111 (CAN Gateway ECO V1.4)

Behaviour of the new version?
The new firmware only evaluates the first two user data bytes of the CAN NMT telegram.


Which products are affected?
EPM-T110 (CAN Gateway V1.3)
EPM-T111 (CAN Gateway ECO V1.3)

What happens?
The module sporadically changes to the PRE-OP state.

When does the problem occur?
The problem occurs if CAN NMT telegrams with more than 2 bytes user data length are received. According to CAN specification, the user data length of CAN NMT telegrams does not exceed 2 bytes.

Possible diagnostics?
The behaviour described before may cause an unintended status change of the module from OP to PRE-OP.

Short-term measures/recommendations?
None.
