The openFT-AC supply return codes that you can query when using SDF-P. Each return code consists of a subcode1 (SC1), a subcode2 (SC2) and the maincode (MC).
Subcode1
Subcode1 represents the error class and is a decimal number.
A distinction is made between the following error classes:
No error:
the value of subcode1 is 0.Syntax error:
the value of subcode1 is between 1 and 31, inclusive.Internal error (system error):
the value of subcode1 is 32.Errors not assigned to any other class:
the value of subcode1 is between 64 and 127, inclusive. If the value of subcode1 is in this range, the maincode must be evaluated to determine the appropriate action.Command cannot be executed at this time:
the value of subcode1 is between 128 and 130, inclusive.
Subcode2
Subcode2 either contains information supplementary to that in subcode1 or is equal to 0.
Maincode
The maincode corresponds to the message key of the SYSOUT message. You can use the /HELP-MSG-INFORMATION command to obtain detailed information. The chapter on Messages contains details on the meanings of the messages and the actions to be taken in response.
See the “User Commands (SDF Format)” manual for a detailed description of the command return codes.
Each command description below shows which command return codes are possible for the command in question and explains the meanings of the return codes.
