Appendix C - Error/Event Tables
The following table reflects codes provided in input
instances 63 and 64 and output instance 5. To acknowl-
edge an error, when the PLC notices a non-zero error
code in instance 64, the PLC logic needs to write the
same code to output instance 5 to remove the error
message pop-up window from the ADM display. After
the event or error is acknowledged by the PLC, the
pop-up window disappears and the error code is cleared
from instance 64. If the condition is no longer present,
the error code is removed from instance 63. If multiple
conditions exist, the process may need to be repeated
for each condition.
The error codes described and presented on input 63
and 64 are the four digit codes presented below in
ASCCI format packed into a 32-bit double word. Each
character of the code occupies a byte within the 32-bit
double word, read right to left.
