Source node not part of Network
Add to Network.
02
Token time-out, node address too large Set the source node’s node address below
the maximum node address.
03
Number of transmit retries exceeded
Check communications with echoback test.
If the test fails, check network.
04
Maximum number of frames exceeded Either check the execution of events in the
network and reduce the number of events
occurring in one cycle, or increase the max-
imum number of frames.
05
Node address setting error (range)
Correct the node address so that it is within
specified range and that there are no node
addresses that are set twice.
06
