(6) Annunciator OFF procedure and processing content
(a) Annunciator OFF procedure
The annunciator can be turned OFF by any of the following instructions.
1) RST F instruction
The RST F instruction turns OFF an annunciator at leading eggs (OFF to
ON) of the input condition.
If an annunciator is turned OFF by the RST F instruction, processing at
annunciator OFF shown in 9.2.4(6)(b) will be performed.
2) OUT F instruction
Although an annunciator can be turned ON/OFF by OUT F instruction, it
takes time longer than when using the RST F instruction since every scan is
processed.
However, if an annunciator is switched OFF by the OUT F instruction, the
"processing at annunciator OFF" ( (6)(b) in this section) is not performed.
Execute the RST F instruction after the annunciator has been switched OFF
by the OUT F instruction.
Remark
Refer to the following manual for details of each instruction.
