we are using Ni-CAN card (driver v2.1) to talk with our haedware, it works fine,
except from time to time, the ncWrite pops up "3FF6206B warning",
I checked the doc, it says:
"CAN bus problems detected (no ack), but communication is
proceeding. This warning corresponds to CAN Error Passive
state. Solutions: Verify that cabling is correct, devices are
connected and operational, and proper bus power is applied. "
BUT, if one of cabling, connection, and proper bus power is not correct, the hardware shouldn't be operational,
the fact is that the hardware seems under fully control, the warning code is really annoying.
Why is that? how to fix it?
your help will be greatly appreciated!
