Overall Operating Procedure for the
CPU Unit
This section gives the overall operating procedure for the NX1P2 CPU Unit and then describes it in
more detail.
1-3-1
Overall Procedure
The overall procedure to use an NX1P2 CPU Unit is given below.
STEP 1. Software Design
Design the overall system configuration, task configuration, programs, and variables.
Step 1-1 Designing I/O and Processing
Step 1-2 Designing Tasks
Step 1-3 Designing Programs
STEP 2. Software Setups and Programming
Create the system configurations that you designed in step 1 on the Support Software and assign
the variables. Create the tasks and programs, and debug them, e.g., with simulations.
Step 2-1 Slave and NX Unit Configurations
Step 2-2 Controller Setup
Step 2-3 Programming
Step 2-4 Offline Debugging
STEP 3. Mounting and Setting Hardware
Mount the Units and make the required hardware settings.
STEP 4. Wiring
Connect the network cables and wire the I/O.
STEP 5. Confirming Operation and Starting Actual System Opera-
tion
Connect the Support Software to the physical system and download the project. Check operation
on the physical system and then start actual system operation.
