values (Analog, Direct Set, or FB
values)
Turn an Input ON at the High Value
19
and OFF at the Low Value (or vice
versa)
Records the accumulated time a
19
signal has been ON
The signal input frequency (On/Off)
is measured for a set length of time.
25
The frequency is compared to a
value range and the Output is turned
ON/OFF according to the result.
A continuous pulse train is output
when this function block is driven.
16
The characteristics of the pulse are
defined as; Pulse duty (Direct set,
Analog, FB values), cycle time.
Output alternates turning ON or OFF
with each input pulse. The last output
status is kept when the power supply
is cycled OFF and ON.
13
However, last output status is lost
when the
Stop mode.

y = A - B
y = A × B

Shift operation; When "SFT" signal is
input, last "I" signal status is output.

When using 8 bit shift operation,
"Shift" function block should be
continued 8 times.
