This manual is intended for the following personnel, who must also have knowledge
of electrical systems (an electrical engineer or the equivalent).
• Personnel with little experience installing FA systems.
• Personnel with little experience designing FA systems.
• Personnel with little experience managing FA systems and facilities.
2 General Precautions
The user must operate the product according to the performance specifications
described in the operation manuals.
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 programming and operating the Unit. Be sure
to read this manual before attempting to use the Unit and keep this manual close at
hand for reference during operation.
WARNING It is extremely important that a PLC and all PLC 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 PLC System to the
above-mentioned applications.
3 Safety Precautions
Caution When power is ON or has just been turned OFF, do not touch the power
supply, I/O terminals, or the surrounding areas. Doing so may result in burns.
After turning the power OFF, wait for the unit to cool down sufficiently before
touching it.
Caution Secure the AC power supply line to the terminal block with a 0.5N
torque. Loosening the screw may result in a fire or malfunction.
Caution Before starting online editing, confirm that the extension of cycle time will
have no adverse effects. Otherwise, input signals may not be read.

Caution With an CP1E E-type CPU unit or with an N-type CPU unit without a Battery,
the contents of the DM Area (D) *, Holding Area (H), the Counter Present
Values (C), the status of Counter Completion Flags (C), and the status of bits
in the Auxiliary Area (A) related to clock functions may be unstable when the
power supply is turned ON.
*This does not apply to areas backed up to EEPROM using the DM backup
function.
If the DM backup function is being used, be sure to use one of the following
methods for initialization.
1. Clearing All Areas to All Zeros
Select [Clear Held Memory (HR/DM/CNT) to Zero] in the [Startup Data
Read] area in the PLC Setup.
2. Clearing Specific Areas to All Zeros or Initializing to Specific Values
Make the settings from a ladder program.
If the data is not initialized, the unit or device may operate unexpectedly
because of unstable data.
4 Application Precautions
Caution Confirm that the facility will not be affected by changing to MONITOR or RUN
mode.

2-2 About the Shutter Control System
This section defines the operation and components of a shutter control system.
2-2-1 Operation

Designing Systems
This section defines the operation of a shutter control system.
A car approaches the shutter.
• When a sensor detects 3 headlight flashes within 5 seconds, the shutter
opens.
• The shutter can also be opened, closed, and stopped with buttons.
• When a sensor detects full car entrance into the garage, the shutter closes.
• When pulling the car out of the garage, use the buttons to operate the shutter.

Allocate
On 14-point I/O units, 8 input relays, from 0.00 to 0.07 (bits 00 to 07 on 0CH),
are allocated to the input terminal block.
Also, 6 output relays, from 100.00 to 100.05 (bits 00 to 05 on 100CH), are
allocated to the output terminal block.
Unused upper bits on the input channel (bits 08 to 15) cannot be used as a work
area. Unused upper bits on the output channel (bits 06 to 15) , however, can be
used.
