Appendix G MSG-SND/MSG-RCV Functions (Ethernet)
G.1 Message Transmit Function (MSG-SND)
A-55
3. Error (error occurred)
Specify a bit that reports that an error has occurred in the message transmission.
When an error occurs, the Error bit will turn ON only for one scan.
Note: For more information about the error cause, refer to G.1.4 ( 2 ) Process Result (PARAM00) and
G.1.4 ( 3 ) Status (PARAM00).
A timing chart of bit type I/O items in the MSG-SND function is as follows:
[In Normal Condition]
[When Forcibly Aborted]
[When Error Occurs]
t
One scan
To continuously command the transmit
execution, turn Execute OFF for one scan
or more after the process completion.
<IN> Execute (executes a transmission)
<IN> Abort (forcibly ends a transmission)
<OUT> Busy (in process)
<OUT> Complete (process completed)
<OUT> Error (error occurred)
t
One scan
To continuously command the transmit
execution, turn Execute OFF for a scan
or more after the process completion.

<IN> Abort (forcibly ends a transmission)
<OUT> Busy (in process)
<OUT> Complete (process completed)
<OUT> Error (error occurred)
