I saw this in the release notes:
| 26695 | Improve start-up sequence of CAN | |
| CAN bus could be disturbed if external CAN modules with speed other than 250kb are active on the bus by start-up. | ||
Since equipping some of the machines with IQAN4 software, we've had some weird errors coming up during the start-up of the software, or outgoing ports going 'red' and not functioning until rebooting the modules seperately using the emergency stop. We've had this with XC10 modules and a XA2 module.
My guess is that it has to do with the boot-time of the modules in combination with the initialization of the CANbus.
Could this solve/improve this issue?

Probably not, case 26695 solves a specific problem when there are modules with speed other than 250 kbps active on the bus at start-up. But, it's worth a try to upgrade to the latest 4.03.27 anyway. If you're problem is repeatable it should be easy to verify if it helps or not.
Note: Make sure you are not using 4.03.26 which was available for a couple of days. That release had problems with XA2 modules at startup, see here.
