CAN communication at 125 kbit/s is not possible

Corrected from:
9400 HighLine V14.13.00.00
9400 Servo PLC V08.13.00.00
 
Response of the new version:
A 9400 with control card hardware version C210/1 = 3A or higher using CAN on-board or a CANopen module can be operated on CAN networks with a baud rate of 125 kbit/s.
 
 
What happens?
It is not possible to operate a 9400 on a CAN network with a baud rate of 125 kbit/s.
The network is either not initialised or other nodes are reporting a bus-off state, when the 9400 is connected.
 
 
When does this behaviour occur?
The behaviour always occurs when 9400 devices equipped with control card hardware version C210/1 = 3A or higher using CAN on-board or a CANopen module are operated on a CAN network with a baud rate of 125kbit/s.
 
 
Which products are affected?
The function restriction only concerns 9400 devices equipped with control card version V3x and higher (C210/1 = 3A or higher) with firmware version:
  • V14.05.00.00 ≥  9400 HighLine ≤ V14.11.00.00
  • V08.05.00.00 ≥  9400 Servo PLC ≤ V08.11.00.00
 
Short-term measures:
Use a different CAN baud rate, e.g. 250 kbit/s.
 
 
Evaluation/recommendations:
In the event of a device replacement during servicing, the device is not compatible. The above remedy using a higher baud rate cannot always be applied because in many cases long cables do not allow higher baud rates.
The probability of occurrence is rather small; the default baud rate is 500 kbit/s.
