Error Judgment Processing - Omron Sysmac F430-F Series Connection Manual

9.3. Error Judgment Processing

This program is divided into the following three ranges ① to ③ and performs Error
Judgment processing. Refer to section 9.8. "Error Processing".
① Error during ExecPMCR instruction execution (ExecPMCR instruction error)
An error during ExecPMCR command execution, such as an error in the main unit or
communication settings, is judged as "ExecPMCR command error". Judgment is made
based on the "Error code (Error ID)" and "Expansion error code (Error IDEx)" of the Exec
PMCR instruction.
② Error when executing protocol macro (Protocol Macro error)
When the protocol macro is terminated abnormally for some reason during execution, it is
judged as "Protocol Macro error". Judgment is made by the sequence Abort end flag
(J01_P2_PmrSeqAbtSta).
③ Partner device error (Remote device error)
An error such as a command error, parameter error, data error, or inexecution error on the
Partner device is judged as a "Remote device error". Judgment is based on the response
data returned from the other device. In this program, the response is not sent back from the
other device at the time of an abnormality, so it is detected as a timeout error of ②.
Since the causes of the abnormalities ① and ② above may be related, all the following
abnormal codes are stored when any of the abnormalities occurs.
・ExecPMCR Instruction error code (ErrorID)
・ExecPMCR Instruction expansion error code (ErrorIDEx)
・Protocol macro error code (lower 4 bits of J01_P2_PmrSta)
・Data transmission error status (J01_P2_TransErrSta)
