Reflect the ON/OFF status of the input devices connected to the input
terminals on the CPU Unit.
Reflect the ON/OFF status of the input devices connected to the input
terminals on the Expansion I/O Units.
The ON/OFF status of these output bits is used to control the output devices
connected to the output terminals on the CPU Unit.
The ON/OFF status of these output bits is used to control the output devices
connected to the output terminals on the Expansion I/O Units.
Work bits can be used only within the ZEN program. I/Os for external devices
cannot be made (i.e., all I/O is internal).
Used the same as the work bits. However, if the power to the ZEN is turned
OFF, these bits also maintain the previous ON/OFF status.
X: ON-delay timer
■: OFF-delay timer
O: One-shot pulse
F: Flashing pulse
W: Twin timer
Hold the present value being counted even if the trigger input or power supply
is turned OFF and continue timing when the trigger input or power is restored.
Reversible 4-digit counters that can be incremented and decremented.
Reversible 8-digit counters that can be incremented and decremented.
CPU Units with DC power supply support a high-speed counter up to 150 Hz.
For details, refer to 8-digit Counter Operation on page 21.
Turn ON and OFF during specified times on specified days.
Turn ON and OFF between specified dates.
Display user-specified messages, times, timer/counter present values, or
analog-converted values.
Used as program input conditions to output analog comparator comparison
results. These bits can be used only for CPU Units with DC power supply.
Compare the present values of timers (T), holding timers (#), and counters
(C). Comparison can be made between the same two counters or timers, or
with constants.
Used to compare the present values of 8-digit counters (F) and output the
comparison results.
Used as program input conditions and turn ON when operation buttons are
pressed in RUN Mode.
