2) Special register (SD62 to 79) data operation when annunciator is tunred
OFF by executing the RST F instruction or BKRST instruction
• The annunciator No. specified by the RST instruction/BKRST instruction is
deleted, and the stored annunciator Nos. after the deleted annunciator No.
are shifted up.
• If the annunciator No. stored at SD64 was switched OFF, the new
annunciator No. which is stored at SD64 is stored at SD62.
• 1 is subtracted from the SD63 value.
• If the SD63 value is "0", SM62 is switched OFF.
3) LED indication
When the annunciator Nos. in SD64 to 79 all turn OFF, the LED (refer to (5)(b)
in this section), which was turned ON as the annunciator turned ON, turns
OFF.
POINT
If the LEDR instruction is executed when annunciator ON and the operation con-
tinuation error having higher priority (
Section 6.21.2) than the annunciator
occur simultaneously, the LEDR instruction clears the error having higher priority
(
Section 6.21.2) than the annunciator.
Hence, the annunciator cannot be turned OFF if the LEDR instruction is executed.
When using the LEDR instruction to turn OFF the annunciator, execute the LEDR
instruction after removing the cause of the error having higher priority than the
annunciator.
