Reset program for a given error alarm relay
● The RST instruction should be used to turn OFF error alarm relays when an error has been
corrected.

Clearing all buffer areas
● To reset all error alarm relays, use RST instruction to specify the system data register SD60,
following the method shown below.
■
Clearing buffer areas and initial data
● Of the areas in which relay numbers are stored, only SD60 and SD61 can be cleared by
directly specifying the system data register with RST instruction.
● When SD60 is specified, all of the error information in the buffer is cleared, and when SD61
is specified, the relay number at the head of the buffer area is cleared, and the buffer is filled
as shown in the example below.
