N section; but the number is too large (i.e., outside the

range Ċ 32,768 to +32,767).

2. A word is transferred from a binary section (I, O, or B

section) to the N or C section and the highĆorder bit is a 1.

3. The destination is in the D section, but the number is not a

Reply Error Codes

The 1775-KA module inserts the reply error code in the STS or EXT STS
bytes of any reply message packet it returns 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 stored at the
command station. Refer to “PLC-3 and PLC-5” for EXT STS bytes.

The meaning of each error code depends on the command message
received from the remote station. The sections below describe the error
conditions that the various commands can generate. The error codes are
listed according to the decimal value that would be stored at the command
initiating station.

When a remote station transmits one of the commands listed below, the
local 1775-KA module might issue a reply message that contains one of
the error codes listed under that command. Error Codes 81 to 88 appear
in the STS byte of the reply message, and Codes 231 to 241 appear in the
EXT STS byte. PLC-2 and PLC Family processors can only display error
codes contained in the STS byte (80-89). Error codes contained in the
EXT STS bytes are only available if either another PLC-3 or computer
originates the command message.
