Remedy
check supply
(24V and 0V),
wait for self-test
Increase the time
span between 2
protocols.
Check the data sizes
of the bus system.
Increase the transmit
priority of the
module.
Check baud rate and
bus connection,
install min. 2 mod-
ules in the network.
Check wiring and
connection of the
nodes and evaluate
