(2) Anunciator ON procedure
(a) Anunciator ON procedure
Anunciator operation can be controlled by the SET F and OUT
F instructions.
1) The SET F instruction switches the anunciator ON only at the leading
edge (OFF to ON) of the input condition, and keeps the anunciator ON
when the input condition switches OFF.
In cases where many anunciators are used, the OUT F instruction
can be used to speed up the scan time.
2) The OUT F instruction can switch the anunciator ON or OFF. It takes
longer to do so than the SET F instruction. If the anunciator is
switched OFF by using an OUT F instruction, this will require the
execution of an RST F or LEDR instruction. Use a SET F
instruction to switch the anunciator ON.
POINT
(1) If switched ON by any method other than the SET F and OUT F
instructions, the anunciator functions in the same way as the internal relay.
(Does not switch ON at SM62, and anunciator Nos. are not stored at SD62,
SD64 to SD79.)
(b) Processing at anunciator ON
1) Data stored at special registers (SD62 to SD79)
a) Nos. of anunciators which switched ON are stored in order at
SD64 to SD79.
b) The anunciator No. which was stored at SD64 is stored at SD62.
c) "1" is added to the SD63 value.
