Ordering Information
■List of models
■Accessories
Note: Memory Cassettes created using the CPU Unit can be read to the CPU Unit, regardless of which model is used, however the following points
must be taken into consideration.
1. When using a Memory Cassette created with a V1 CPU Unit for a Pre-V1 CPU Unit, use the Memory Cassette within the ranges for the
Pre-V1 CPU Unit's timers, holding timers, counters, weekly timers, calendar timers, and displays.
2. When using a Memory Cassette created with a CPU Unit with 20 I/O points for a CPU Unit with 10 I/O points, use only up to 6 inputs and
4 outputs for the I/O bit area.

Name Symbol Bit addresses No. of points Operation Details 2
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.

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.

The counter bit turns ON when the counter value (present value)
reaches the set value (present value ≥set value). The count returns
to 0 and the counter bit turns OFF when the reset input turns ON.
Count inputs are not accepted while the reset input is turned ON.
The counter present value and counter bit (ON/OFF) are held even if
the operating mode is changed or the power supply is interrupted
.

but the power supply and load connections can be swapped
