This may be a one-off read error,
please repeat the process. If the
error occurs again, please contact
HBM Service.
Check that the termination resis-
tors are present or whether a
channel is faulty. Then switch the
devices back on. If this does not
help, connect the devices to the
CAN bus one at a time, to find out
which device is faulty.
Restart, send the MP85A process
controller to the manufacturer
(HBM)
Check the CAN bus configuration
