Programmable Relay ZEN 7
Operation
■ Bits
Note: * CPU Units with 10 I/O points have 6 input bits (I= to I5) and 4 output bits (Q0 to Q3).

Input bits I I0 to Ib* 12 Reflect the ON/OFF status of the input devices
connected to the input terminals on the CPU Unit.
-
Expansion input
bits
X X0 to Xb 12 Reflect the ON/OFF status of the input devices
connected to the input terminals on the Expan-
sion I/O Units.
Output bits Q Q0 to Q7* 8 The ON/OFF status of these output bits is used
to control the output devices connected to the
output terminals on the CPU Unit.
1
Expansion output
bits
Y Y0 to Yb 12 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 M M0 to Mf 16 Work bits can be used only within the ZEN pro-
gram. I/Os for external devices cannot be made
(i.e., all I/O is internal).
Holding bits H H0 to Hf 16 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.
Timers T T0 to Tf 16 X: ON-delay
timer
Functions are
selected from
the screen
when parame-
ter settings are
made.
Time units can
be selected
from the follow-
ing: 0.01-s unit:
0.01 to 99.99 s
min/s unit: 00
min 01 s to 99
min 59 s h/s
unit: 00 h 01
min to 99 h 59

: (box) OFF-
delay timer
O: One-shot
pulse timer
F: Flashing
pulse timer
Holding timers # #0 to #7 8 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.
Counters C C0 to Cf 16 Reversible counters that can be incremented and
decremented.
3
Weekly timers @ @0 to @f 16 Turn ON and OFF during specified times on
specified days.
4
Calendar timers * *0 to *f 16 Turn ON and OFF between specified dates.
5
Display bits D D0 to Df 16 Display any character string, time, or analog-con-
verted display of timer or counter present values.
6
Analog compara-
tor bits
A A0 to A3 4 Used as program input conditions to output ana-
log comparator comparison results. These bits
can be used only for 24-VDC input CPU Units.
7
Timer/counter
comparator bits
P P0 to Pf 16 Compare the present values of timers (T), hold-
ing timers (#), and counters (C). Comparison can
be made between the same two counters or tim-
ers, or with constants.
8
Button input bits B B0 to B7 8 Used as program input conditions and turn ON
when operation keys are pressed in RUN Mode.
These input bits can be used only with LCD-type
CPU Units.
