General Precautions 1
1 General Precautions
The user must operate the product according to the performance
specifications described in the operation manual.
Before using the product under conditions which are not described in
the manual or applying the product to nuclear control systems,
railroad systems, aviation systems, vehicles, combustion systems,
medical equipment, amusement machines, safety equipment, and
other systems, machines, and equipment that may have a serious
influence on lives and property if used improperly, consult your
OMRON representative.
Make sure that the ratings and performance characteristics of the
product are sufficient for the systems, machines, and equipment, and
be sure to provide the systems, machines, and equipment with
double safety mechanisms.
This manual provides information for installing and operating
OMRON Motion Control Units. Be sure to read this manual before
operation and keep this manual close at hand for reference during
operation.
!WARNING It is extremely important that a PC and all PC Units be used for
the specified purpose and under the specified conditions,
especially in applications that can directly or indirectly affect
human life. You must consult with your OMRON representative
before applying a PC system to the above mentioned
applications.
2 Safety Precautions
Confirm safety before attempting any of the following operations.
• Transferring the user program
• Changing the user program
• Changing the operating mode of the ZEN
• Turning relays ON or OFF
Always perform a program check on any program after writing it and
before transferring it to the ZEN. Also confirm the operation of the
program completely before using it for actual system operation.
Always disconnect the output circuits before performing operating
tests on systems in which the loads connected to the output circuits
can have a serious effect on human life or property if incorrect
operation occurs.
xvi
Application Precautions 3
3 Application Precautions
Observe the following precautions when using the ZEN Support
Software.
• Observe the following precautions before starting the ZEN
Support Software
• Close all software programs not related to the ZEN Support
Software. It is particularly important to close all programs
that start periodically or intermittently, such as screen savers,
virus checkers, email and other communications programs,
and schedulers.
• Do not share hard disks, printers, or other devices with other
network computers while running the ZEN Support Software.
• Some notebook computers set the RS-232C port to modem
or infrared application by default. Change the settings
according to the operating instructions for your computer so
that the RS-232C port can be used as a normal serial
communications port.
• Some notebook computers set the RS-232C port to not
supply power (5 V) to the port to save energy by default.
Change the settings according to the operating instructions
for your computer to provide power to the port. (There are
Windows settings and also possibly settings for computerspecific utilities or BIOS settings to save power.)
• Do not turn OFF the power supply to the ZEN or disconnect the
connecting cable while the ZEN Support Software is online with
the ZEN. The computer may malfunction.

System Software (See note 1.)
The system software was upgraded to
version 1.1.
Main Changes
The following display functions have been
added to LCD-type CPU Units.
• Clear display function
• The display object DAT1 (day/month)
System Software (See note 1.)
The system software was upgraded to
version 2.0.
(“-V1” was added to the CPU Unit model
number.)
Main Changes (See note 2.)
• The number of timers, counters, weekly
timers, calendar timers, and display bits
was increased from 8 to 16. The number of
holding timers was increased from 4 to 8.
• A 20-point CPU Unit was added to the
lineup.
System Software (See note 1.)
The system software was upgraded to
version 3.0 (“-V2” was added to the CPU Unit
model number.)
Main Changes (See note 2.)
• Addition of multiple-day operation and
pulse-output operation to the weekly timers
• Addition of twin time operation to the timers
• Addition of an 8-digit counter and 8-digit
comparators
• Addition of models with communications
(10-point models only) and economy CPU
Units
• Addition of daylight saving time settings for
Australia and New Zealand
• Deletion of contrast control
ZEN CPU Unit ZEN Support Software
Changes Applicable from
Version 2.0 (ZEN-SOFT01-V2)
• Changed to handle additional
display functions.
• Simulation function added.
• Improvements made to
functions, operability, and
display.
Changes Applicable from
Version 3.0 (ZEN-SOFT01-V3)
• Changed to handle the
memory area expansion in
“-V1” CPU Units.
• Changed to handle addition
of 20-point CPU Units.
Support for Version 4.0 or
Higher (ZEN-SOFT01-V4)
• Supports CPU Units with
enhanced functionality (-V2)
• Supports half-sized I/O
Expansion I/O Units (-8E1)
• When the type of the CPU
Unit (the CPU Unit and
Expansion I/O Unit
configuration) is the same as
that specified in the property
settings of the Support
Software, program transfer is
possible even if Expansion I/
O Units are not connected.
Note 1. “System software” is the software for processing the CPU Unit’s program.
With LCD-type CPU Units, the system software version can be read by
selecting Other/System information from the menu. With “-V2” CPU Units,
“V03.00” will be displayed as the system software version.
2. Refer to page 15 for the memory area differences between versions.

Note 1. With LCD-type CPU Units, the system software version can be read by
selecting Other/System information from the menu. With “-V2” CPU Units,
“V03.00” will be displayed as the system software version.
2. The setting for a display bit (D) will appear as follows:
• If “DAT1: day/month” is set for display, the LCD display will show T#
and the display function will not operate.
• If “C (clear)” is set, the LCD display will appear as
[--| |-----------0D0] and the display function will not operate.
Note The above operations were not supported in ZEN versions prior to 1.1.

Support Software Version Upgrades Appendix B
3. When reading out the program from the ZEN, the following items will be
determined based on the display function (D) settings contained in the
program.
• If "DAT1: day/month" is set, CHR (character designation) will be set.
• If "C (clear)" is set, the display function (D) will be deleted from the
program.
Note The above operations were not supported by ZEN Support Software
versions lower than 2.0.
4. Cannot be used with 20-point CPU Units.
Restricted to use within the memory area range of Pre-V1 CPU Units.
