Remote Error Codes Received from the
1773-KA Module
Appendix B
BĆ14
If the remote station has a 1771–KG, 1771–KA, or 1774–KA module, the
remote error codes will have the meanings listed in the table below:
Error
Code
Meaning
81
This error is sent from the remote station if the command
message was incorrect. This includes the command code,
subcommand code, and size of the command or the requested
reply size. This error results in the setting of the remote error bit
for the associated rung.
83
Some condition exists at the remote PC that requires manual
intervention:
The cable between the module and the PC is unplugged.
The PC is faulted.
Either results in setting the remote error bit for the associates
rung.
84
Execution of a message at the remote station was aborted
because of a hard communication error on the cable or on
backplane access between the module and the PC. This error
results in the setting of the remote error bit for the associates
rung.
85
An attempt to access an illegal address in the remote PC has
aborted message execution. Illegal accesses may result from:
Access outside the data table as defined at the remote station.
Access outside a memory access window (protected commands
only).
Either results in setting the remote error bit for the associated
rung.
86
Execution of a command is disabled at the remote station by a
DIP switch option. This error results in setting the remote error
bit for the associates rung.
87
The remote PC is in PROGRAM or REMOTE PROGRAM
mode, or the remote KA is in download mode. This error results
in setting the remote error bit for the associated rung.
88
Execution of protected commands at the remote station is
inhibited because its PROG light is on. This error results in
setting the remote error bit for the associated rung.
89
The remote station has no memory to store messages. This error
will only be signalled after 5 re-tries at half second intervals.
