When the contacts C013 and C015 are ON at
the same time, the set priority Q1 output 1
This bistable function block
implements the priority setting of
the Q1 output. If SET1=TRUE is entered ,

set. If RESET = TRUE , the Q1 output is
reset. If both inputs are TRUE ,
the Q1 output is set to TRUE by SET1 .
10.2.8 TOF (Delayed Off Timer Instruction )
LD, FBD programming language
Function: The
TOF
instruction is used to implement the delay disconnect function. If the
input terminal
IN
is
TRUE
, the output terminal
Q
immediately becomes
TRUE;
if the input
terminal
IN
is changed from
TRUE
to
FALSE
, the output terminal
Q
will be delayed by a certain
time and then by the
TRUE.
It becomes
FALSE
, the delay time is the value of
PT
, and the
ET
end
records the time between the time when the
IN
changes to
FALSE and
the time when the
Q
end
changes to
TRUE
.
