CJ-series Serial Communications Units Operation Manual for NJ-series CPU Unit(W494)
Meaning
This flag is changed to TRUE when a
sequence is waiting due to the Wait command.
Waiting is released when the Wait Release
Switch is changed from FALSE to TRUE in the
user program, and the sequence will move to
the next step.
Note Make sure to set the Wait Release
Switch from FALSE to TRUE from the
user program.
This flag is changed to TRUE when the Serial
Gateway (Mode) is prohibited due to the status
of the Serial Gateway Prohibit Switch in the
user program. This flag is changed to FALSE
when the Serial Gateway is not prohibited.
The contents of the error codes are shown in
the following table.
Code Error contents
0 No error
Sequence No. Error
The sequence number specified
2
by the ExecPMCR instruction
does not exist in the Unit.
Data Read/Write Area Exceeded
Error
3
When data is written or read to
the CPU Unit, the specified area
range was exceeded.
Protocol Data Syntax Error
A code that cannot be executed
4
occurs while the protocol macro
was executed. (Example: A
header comes after a terminator.)
No codes other than the above are used.
When an error occurs, the error code is held
until the next sequence starts.
The error code is cleared when the Unit is
restarted, or when the next sequence execu-
tion starts.
The current communications sequence num-
ber is set when the sequence execution starts.
The number is set even when a sequence
number error (Error Code: 2) occurs.
Step numbers 0 to 15 (0 to F hex) for which
execution is complete are stored.
