# Connect the Device and PLC with AOP

To create an implicit messaging connection between a PLC and 3D-L4000 firmware using the AOP:

1. Open the RSLogix 5000 and load the PLC project.

2. Under the I/O Configuration node, select the Ethernet Node beneath the Ethernet Module, right-click on the icon and click Select New Module... to open the Select Module Type dialog.

3. In the Select Module Type dialog, select the In-Sight 3D-L4000 Vision System.

4. After selecting 3D-L4000 Vision System, the New Module dialog displays. Fill in the Name field and either the IP Address or the Host Name fields in the General tab.

   - Name: Fill in the name for the In-Sight 3D Vision System. The RSLogix 5000 creates tags based on this name.
   - IP Address: Enter the IP address for the In-Sight 3D Vision System.
   - Host Name: Enter the Host Name of the In-Sight 3D Vision System. Use this setting only when there is a Domain Name Server (DNS) on the network.
   - Description: You can add notes here about the vision system you are adding.

5. Click on Change... in the Module Definition tab to select the size and type of data. The default data type is DINT-8 for both Input Results from Sensor and Output Data to Sensor for 32 bytes total. To change the default settings, select the data type for Input and Output from the dropdown menu:

   - DINT
   - INT
   - REAL
   - SINT

6. On the Connection tab, fill in the field and check the checkboxes:

   - Requested Packet Interval (RPI): Defines the amount of time (in milliseconds) between data exchanges across an implicit messaging connection. The default RPI value is 60 ms.
   - Major Fault on Controller if Connection Fails While in Run Mode: When you select this option, the controller generates a major fault if the connection fails.
   - Inhibit Module: Prevents the PLC from attempting to establish a connection with an In-Sight vision system.
   - Use Unicast Connection over Ethernet/IP: This checkbox is checked in by default. Do not uncheck it. If you uncheck this checkbox, the Logix5000 PLC uses a Multicast Connection over Ethernet/IP which can cause too much traffic in other subnets of the network.

After performing the connection procedure, the RSLogix 5000 creates tags that map to the Input and Output data of the In-Sight 3D Vision System using the name you created in Step 4.
