Basic Operating Procedure
In general, use the following procedure.
1. Setting Devices and Hardware
Connect the CPU Unit, Expansion I/O Units, and Expansion Units.
Set the DIP switches on the Option Board and Expansion Units as required.
Refer to Section 3 Part Names and Functions and Section 5 Installation and Wiring in the CP1E CPU Unit
Hardware User's Manual (Cat. No. W479).
2. Wiring
Wire the power supply, I/O, and communications.
Refer to Section 5 Installation and Wiring in the CP1E CPU Unit Hardware User's Manual (Cat. No. W479).
3. Connecting Online to the PLC
Connect the personal computer online to the PLC.
Refer to Section 4 Programming Device in the CP1E CPU Unit Hardware User's Manual (Cat. No. W479).
4. I/O Allocations
Allocations for built-in I/O on the CPU Unit are predetermined and memory is allocated automatically
to Expansion I/O Units and Expansion Units, so the user does not have to do anything.
Refer to Section 6 I/O Allocation in the CP1E CPU Unit Software User's Manual (Cat. No. W480).
5. Software Setup
Make the PLC software settings.
With a CP1E CPU Unit, all you have to do is set the PLC Setup.
When using an E-type CPU Unit or when using an N/NA-type CPU Unit without a Battery, be sure to
consider selecting the Clear retained memory area (HR/DM/CNT) Check Box in the Startup Data
Read Area in the PLC Settings.
Refer to 3-2-4 Initializing I/O Memory at Startup, Section 7 PLC Setup in the CP1E CPU Unit Software
User's Manual (Cat. No. W480).
6. Writing the Programs
Write the programs using the CX-Programmer.
Refer to Section 4 Programming Concepts in the CP1E CPU Unit Software User's Manual (Cat. No. W480).
7. Checking Operation
Check the I/O wiring and the Auxiliary Area settings, and perform trial operation.
The CX-Programmer can be used for monitoring and debugging.
Refer to Section 8 Overview and Allocation of Built-in Functions.
