9.8. Error processing

The following gives the details of errors that may occur during the program execution.
9.8.1. Protocol Macro Error Code
The SCU detects an error by monitoring the macro operation.
The error codes include (1) PMCR instruction error or (2) Communications error
(transmission error, etc.) and are stored in H400 Output_PMCR_ErrorCode.

(1)PMCR
instruction error
(1)PMCR
instruction error
(2)Communications
error
An error is detected on Destination Device.
Description
The sequence number specified by
the PMCR instruction does not exist
in Unit.
When data is written or read to CPU
Unit, the specified area range is
exceeded.
A code that cannot be executed
occurs while the protocol macro is
being executed. (Example: A header
occurs after a terminator.)
Communications cannot perform due
to an error in the transmission path,
etc.
