Precautions during programming
It is not possible to execute multiple F152_RMRD instructions and F153_RMWT instructions at the
same time.
The program should be set up so that these instructions are executed when the
F152_RMRD/F153_RMWT instruction execution enabled flag (R9035) is on.
R9035
0: Execution inhibited (RMRD/RMWT instruction being executed)
1: Execution enabled
The F152_RMRD instruction only enables a request to be accepted. The actual processing is
carried out at the end of the scan. The F152_RMRD/F153_RMWT instruction completed flag
(R9036) can be used to confirm whether or not the instruction has been executed.
R9036
0: Completed normally
1: Completed with error (The error code is stored in DT9036/DT90036)
DT9036
If the transmission has been completed with an error (R9036 is on), the contents of the
(DT90036)
error (error code) are stored.
Reference: The error codes stored in the DT9036/DT90036
Error code (HEX)

16#68
16#71
16#72
16#73
If the error code is 16#71 to 16#73, a communication time-out error has occurred. The time-out
time can be changed within a range of 10.0ms to 81.9s (in units of 10ms), using the setting of
system register 32. The default value is set to 2 seconds.
