The following procedure outlines the recommended steps to follow when pre-
paring CJ-series PLCs for operation.
1. Installation
Set the DIP switches on the front of each Unit as required.
Connect the CPU Unit, Power Supply Unit, I/O Units, and End Cover. In-
stall a Memory Card if required.
See 5-2 Installation for details.
2. Wiring
Connect the power supply wiring, I/O wiring, and Programming Device
(CX-Programmer or Programming Console). Connect communications
wiring as required.
See 5-3 Wiring for details on power supply and I/O wiring.
See 2-3 Basic System Configuration for details on connecting Program-
ming Devices.
3. Initial Settings (Hardware)
Set the DIP switches and Rotary switches on the CPU Unit and other
Units.
4. Checking Initial Operation
a) Set the operating mode to PROGRAM mode and connect the Pro-
gramming Console.
b) Turn the power ON after checking the power supply wiring and volt-
age. Check the Power Supply Unit's POWER indicator and Program-
ming Console's display.
5. Registering the I/O Tables (If Required.)
Check the Units to verify that they are installed in the right slots. With the
PLC in PROGRAM mode, register the I/O tables from the CX-Programmer
(online) or Programming Console. (Another method is to create the I/O ta-
bles in CX-Programmer (offline) and transfer them to the CPU Unit.)
See 8-1 I/O Allocations for details.
6. PLC Setup Settings
With the PLC in PROGRAM mode, change the settings in the PLC Setup
as necessary from the CX-Programmer (online) or Programming Console.
(Another method is to change the PLC Setup in CX-Programmer (offline)
and transfer it to the CPU Unit.)
7. DM Area Settings
a) Use a Programming Device (CX-Programmer or Programming Con-
sole) to make any necessary settings in the parts of the DM Area that
are allocated to Special I/O Units and CPU Bus Units.
b) Reset the power (ON → OFF → ON) or toggle the Restart Bit for each
Unit. See the Unit's operation manual for details.
8. Writing the Program
Write the program with a Programming Device (CX-Programmer or Pro-
gramming Console).
9. Transferring the Program (CX-Programmer Only)
With the PLC in PROGRAM mode, transfer the program from CX-Pro-
grammer to the CPU Unit.
