Correcting an error code C:
This error code indicates a network failure. If the module is a master

drop, no other drops are functional on the network. If the module is

a slave drop, it is not receiving any messages from the master drop

and the data contained in its dual port memory will remain at the last

value written to it. The data targeted for that drop will remain frozen

in the dual port memory of the other slaves on the network. This

fault code is reset whenever the line goes active. The causes of a

network failure are incorrect drop depth specifications or lack of

cable system integrity.
The master logs the error parameters (RECEIVE TIMEOUTS, CRC,

OVERRUN, and ABORT) for the entire network. Monitoring these

registers will indicate cable system integrity or lack of it. A few errors

may accumulate over a period of time, such as a few days; but,

when these parameter values increase consistently over a short

period of time, there is a problem with the integrity. If this occurs,

monitor the error parameters of each Network module to isolate the

problem.
