Response Code List

Command codes are represented by a 2-byte hexadecimal code. FINS com-
mands always begin with a 2-byte command code; any parameters required
follow the command code.
The response code consists of a 2-byte hexadecimal code indicating the
results of command execution. The first byte provides the main response
code (MRES), which classifies the results, the second byte provides the sub-
response code (SRES), which contains details about the results.
The command codes listed in the following table are supported by the PROFI-
BUS Master Unit. A PLC program can send these to the Unit

Response codes are 2-byte codes which indicate the results of command
execution. They are returned in the response following the command code.
The first byte of a response code is the MRES (main response code), which
categorizes the results of command execution. The second byte is the SRES
(sub-response code) which specifies the results.
