Error Codes

This appendix describes the error codes that the 1775–KA module will

report. Errors are of three types:

local

remote

The 1775–KA module generates local errors while trying to execute one

of its own message procedures. The module stores local error codes

under the user symbol ERROR. Possible local errors are listed in section

titled Local and Reply Error Codes.

The 1775–KA module generates reply errors while trying to respond to a

command message received from a remote Data Highway station. The

1775–KA module inserts the reply error code in the STS or EXT STS

bytes (Appendix A) of any reply message packet it transmits to a remote

station. For reply errors, there is a direct correlation between the error

codes in the STS and EXT STS bytes of reply messages and the error

codes reported at the remote station. The correlation is as follows:
