High−level Instructions
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
with the ED instruction. 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 error (error
(DT90036) code) are stored.
Reference: The error codes stored in the DT9036/DT90036
Error code (HEX) Description
H5B
Time−out error (no intelligent unit found at the specified location.)
H68
No memory error (no memory exists at the specified address.)
H71
Send answer time−out error
H72
Send buffer full time−out error
H73
Response time−out error
If the error code is H71 to H73, a communication time−out error has occurred. The time−out time can be
changed within a range of 10.0 ms to 81.9 s (in units of 10 ms), using the setting of system register 32. The
default value is set to 2 seconds for FP3 and 10 seconds for FP2/FP2SH/FP10SH.
