Assignment of I/O channel and
relay numbers
Note:
The ON time of a 0.1s clock is 50ms. If a longer time is required for
program execution, the CPU may fail to read the clock.
Relay 1901
This relay is used to generate a 0.2s clock. When used in conjunction with
a counter, it functions as a long-time timer that can retain its present value
during power failure.
Relay 1902
This
relay
is
used
to
generate
a
ts
clock.
When
used
in
conjunction
with
a
counter,
it
functions
as
a
long-time
timer
that
can
retain
its
present
value
during
power
failure.
The
relay
output
can
be
also
used
as
a
flicker
signal.
Relay 1903
This
relay
turns
ON
when
the
result
of
an
arithmetic
operation
is
not
output
in BCD form.
Relay 1904
This relay serves as a carry flag and operates or releases according to
the result of an arithmetic operation. It can be forcibly turned ON by the
SET CARRY (STC) instruction and turned OFF by the CLEAR CARRY
(CLC) instruction.
Relay 1905
This relay turns ON if the result of the COMPARE (CMP) instruction is “>"
(more than).
Relay 1906
This
relay
turns
ON
if
the
result
of
the
compare
operation
is
“=”
(equal
to).
it may also turn ON if the result of an arithmetic operation is 0.
Relay 1907
This relay turns ON if the result of the compare operation is "<" (less
than).
Relays TRO to 7
These are temporary memory relays and may not necessarily be
assigned
in
sequence.
The
same
coil
number
of
these
relays
must
not
be
used
in
duplicate
within
the
same
block
of
a
program.
However,
the
same
coil number can be used in a different block. When using a temporary
memory
relay,
the
letters
“TR”
must
be
prefixed
to
the
relay
number
(¢.g.,
TRO).
