At the leading edge (from OFF to ON) of a count input signal, the counter
decrements by a value of 1.
When
a
count
input
and
a
reset
input
are
simultaneously
applied,
the
reset
input
takes
precedence.
No
counting
will
be
performed
after
that
even
if
the
reset
input
is
removed.
If
a
power
failure
occurs,
the
current
count
value
(the
number
of
counts
remaining)
is
retained
in
memory
and
the
counter
is
not
reset.
The
set
value
for
the
TIM/CNT
instruction
cannot
be
set
on
a
channel
basis.

Function
Serves as temporary memory relay
Remarks
To program a temporary memory relay, the TR instruction must be used
with an OUT or LD instruction.
The TR instruction is used when a ladder diagram cannot be program-
med with the interlock instructions. In an output branching circuit
consisting of multiple blocks, temporary memory relays are used at each
point. These temporary relays cannot be used in duplicate within the
same block but can be used within different blocks,
Relay numbers can be from 0 to 7.
