Establish the Connection Using the Add-On Profile

This topic covers how to establish an implicit messaging connection with a single ControlLogix PLC using the Add-On Profile (AOP) for an In-Sight vision system running 4.x.x firmware.

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

   Note: The PLC must be Offline to add connections in RSLogix 5000.

2. Under the I/O Configuration node, select the Ethernet Node under the Ethernet Module, right-click on the icon and select New Module from the menu:

   

3. When the following dialog appears, select your model of In-Sight Vision System from the list. This option will appear once the Add-On Profile (AOP) is installed.

   

4. After the selection is made, the configuration dialog for the In-Sight Vision system will be displayed:

   Note: The Time Sync tab is displayed only when connected to an In-Sight 5000 series vision system. For more information, see Time Sync Tab- In-Sight 4.x.x Firmware.

   

   The following fields need to be configured:

   • Name: This is the name given to the generic EtherNet/IP device; the tags created in RSLogix 5000 will be based on this name. It is recommended that the In-Sight vision system's name be used, to maintain consistency.
   • IP Address: The IP address of the In-Sight vision system.
   • Host Name: This setting is optional; only use this setting if there is a Domain Name Server (DNS) on the network.
5. The Change button can be used to set the amount and type of data to be transferred between the In-Sight Vision System and the PLC. Electronic Keying can also be enabled using this button.

6. (Optionally) The electronic keying can be disabled using the Change button if necessary.

   To disable keying: In the Module Definition dialog, select Revision 10 and select Disable Keying. Then click OK.

   

7. After accepting the general communication parameters, the next step in the configuration process is displayed in the figure below:

   

   The following fields can be configured:

   • Requested Packet Interval (RPI): This field specifies the Requested Packet Interval (RPI), which defines the amount of time (in milliseconds) between data exchanges across an implicit messaging connection.

     Note: Beginning in In-Sight firmware version 3.30.00, the RPI value no longer has to be longer than the job execution time; implicit messaging connections now run asynchronous to the job execution. However, small RPI times (<20ms) may negatively impact the performance of vision jobs. For best results, the RPI time should be set to no more than half the time between when the In-Sight vision system completes the job execution and when the PLC requires the data.
   • Major Fault On Controller If Connection Fails While in Run Mode: This option will cause the controller to generate a major fault when the connection fails.

   • Inhibit Module: Checking this box prevents the PLC from attempting to establish a connection with an In-Sight vision system.

     Note: If the In-Sight vision system appears to be stuck in "Standby" mode, then inhibiting and re-enabling the module can cause the module to become operational again.

8. After adding the module to ControlLogix, the I/O tree should appear as follows:

   

9. RSLogix 5000 will then create tags that map to the In-Sight vision system's Input and Output Data, based on the name given to the device.

   • InSight_Top:I Scheduled Input: The table below represents the data that is sent FROM the In-Sight vision system to the PLC:

     

   • InSight_Top:O Scheduled Output: The table below represents the data sent TO the In-Sight vision system from the EtherNet/IP client (ControlLogix):
