Introduction

This example demonstrates usage of PLCnext I/O. The PLCnextIO component is able to read values from the CDPIO PLCnext extension app to update configured CDP channels (signals) with values to and from CDP.

Set up the I/O

This example requires that the following is set up:

• An AXC F 2152
• An AXL-F-AI2-AO2-1H (AI2 + AO2) I/O module
• Power and ground connection to the I/O and the I/O module
• Ethernet connection to the host computer
• Connect AXL-F-AI2-AO2-1H 00 with AXL-F-AI2-AO2-1H 02
• Connect AXL-F-AI2-AO2-1H 10 with AXL-F-AI2-AO2-1H 22

The above image shows how the AXC F 2152 is set up for this example.

Set up a Test-system

First we set up a System that the PLCnexIO can be tested in:

Create a system named "PLCnext" with a Console application named PLCnextApp, then select Configure mode. See How to Create a system for more information.

Add a Test Component

In the below steps, we add a component to generate some test-data for our I/O.

• Select the PLCnextApp that resides under PLCnext in the Project tree.
• Select/expand CDPCore in the Resource tree, right-click on Sine and select Add.
• Select the newly added Sine component.
• In the Parameters table, set Amplitude to 16000
• Set Offset to 16000
• Right-click on the Output signal and select Copy Path, as we want to connect this later.

Add a PLCnextIO Component

In the below steps, we add a PLCnextIO component to the system, and add a module to the I/O.

• Select the PLCnextApp that resides under PLCnext in the Project tree.
• Expand PLCnextIO in the Resource tree, right-click on PLCnextIO and select Add.

Add a Module and Configure It

• Select the PLCnextIO in the Project tree.
• In the Resource tree, type in AI2 in the 'Search' field.
• Double-click the 'AXL-F-AI2-AO2-1H' module to add it into the PLCnextIO.
• Double-click PLCnextIO in the Block Diagram to see the added module
• Right-click on the port for AO0 and select Connect From 'PLCnextApp.Sine.Output'

Select Toolkit and Pair

• Select PLCnext in the Project tree.
• Select the Deploy Configuration tab
• In the Networks table, select the network that the physical PLCnext device is on.
• In the Devices table, find the IP-address of the PLCnext device.
• Double-click on the IP-address in Name-column to rename it to PLCnext, then type in root into Username, and select 'Pair'. Enter the password if a dialog pops up.
• In the Applications table, select Device 'PLCnext' and select PLCnext ARMv7 32-bit Toolkit

How to Run the Tutorial

To run the tutorial from CDP Studio, select Configure mode, right-click on the system project and select Run & Connect. See the Running and Connecting to the System tutorial for more information.

Verify That It Works

• Click into PLCnextApp.AXL-F-AI2-AO2-1H.
• Verify that the sine value propagates from the Sine output into AO0 and back in from AI0.
