Diagnostics and troubleshooting
1
Status of CAN physical layer:
Bits representing CAN errors (because there may be multiple errors)
0: no errors
Bit 0: not used
Bit 1: CAN error passive (CAN error counter(s) >=127, too many error frames)
Bit 2: CAN overflow (too many can messages in a too short time)
Bit 3: error control (Node-guarding or Heartbeat error event)
Bit 4: Sync error (Sync object not received within configured communication cycle)
Bit 5: Bus-Off (CAN controller in Bus-Off state or fatal error on option card)
2
Status of the CANopen network state-machine:
0: CANopen in initialization state
1: Executing a Reset or Fatal Error
2: CANopen in pre-operational state
3: CANopen in stopped state
4: CANopen in operational state
3
counter for PDO telegrams received error-free since power on.
4
counter for telegrams transmitted since power on.
5
counter for all telegrams received error-free since power-on.
this counter includes all CanBus messages, including those not directed to this module.
6
CAN Error counter and Fatal Code
Value > 32767: Fatal Error Code.
0 – 32767 error counter. Counter wraps around back to 1 when count > 32767. Increments
on any CAN passive error, CAN busoff error or CAN overflow error.
If this value is changing rapidly and warning = A0701 then the CAN bus is overloaded.
•
If this value is changing rapidly and warning = A0700 or A0702 then the CAN bus is not
healthy.
Check and if required correct most significant digit of P2041.04 (baud rate) for every bus
node
