Remote Error Codes Received from the
1773-KA Module
Appendix B
BĆ3
When a remote station transmits a command, the local 1775–KA module
might issue a reply message that contains one of the error codes listed in
section titled Local and Reply Error Codes. Error codes 81 to 87 appear
in the STS byte of the reply message, and codes 231 to 241 appear in the
EXT STS byte (Appendix A).
The local PLC–3 station receives remote error codes in a reply to a
command it has sent to a remote station. These error codes are stored
under user symbol ERROR in the local PLC–3 station.
The extended address for the beginning of the error block file is
$E2.5.nn.4.0
where nn is the thumbwheel number of the 1775–KA module. You can
access this error block by any one of the following means:
displaying it through the front panel of the PLC–3 controller
using the data monitor mode of the Industrial Terminal (cat. no.
1770–T4)
using the move status (MVS) command in the PLC–3 ladder diagram
program
using the I/O Scanner–Message Handling Module (cat. no. 1775–S4B)
using the 1775–KA module
The meaning of a particular remote error code will vary, depending on the
type of communication interface module at the remote station. For
example, if the remote station is a PLC–3 processor with a 1775–KA
interface module, the remote error codes will have the meanings listed in
section tilted Local and Reply Error Codes. For the meanings of other
remote error codes, refer to the appropriate user’s manual for the
communication interface module at the remote station.
