Allen-Bradley EtherNet/IP (Client) SLC5/05 Setup

 Topic: CM115

The following information applies for Allen-Bradley SLC 5/05 PLC compatible with C-more Panels using EtherNet/IP (Client) Protocol.

 

Note: Requires SLC 5/05 Series A, FW Rev. OS501, FRN5. All Series B and C are supported.

Setup RSLogix 500

To Setup the RSLogix 500 for this PLC, follow these steps:

  1. In RSLogix 500 choose Channel Configuration in the left navigation window.

  1. From the Channel Configuration window shown below, choose the Chan. 1 - System tab.

  1. Set the following:
  • For the IP Address field, this is the IP Address that you enter in the C-more Panel Manager.
  • For the Subnet Mask, enter the same Subnet Mask as set in the C-more Panel Manager.
  • For the BOOTP Enable option, tick the box to turn it off. C-more needs a static IP Address to connect.
  • Leave all remaining settings as default.
  • Click on the OK button to close the Channel Configuration window.

C-more Protocol Manager Settings

  1. Do one of the following:
  • Click the Protocol Manager button on the Home tab
    — or —
  • Click the Protocol Manager button on the Setup tab
    — or —
  • from the Navigation window, click the Function tab, click Setup and then select Protocol Manager.

  1. From the Protocol Manager window, click the Device name on the tree to the left.
  • The Device Setup window opens.
  1. From the PLC Protocol field, click on the down arrow and select Allen-Bradley EtherNet/IP Client (SLC5/05/ENI Adapter).

When you select a different PLC Protocol than the one currently in use, the warning Message shown below appears.

  • Click Yes to accept.

From the Panel Manager window shown above, configure each field as follows:

  1. IP Address: The IP Address of the Allen-Bradley PLC that you are targeting.
  2. Port (0-65535): The target TCP Port Number.

 

Note: If you are on the same Local Network as the Allen-Bradley PLC, you should always use 44818. Only use a different Number if trying to go through or a Router or if instructed so by your Local Network Administrator.
  1. Retries: This is the Number of Times that the Panel will Retry to send a Message if the request does not receive a reply in the specified Timeout period. Once the Retry count has been reached, the Panel will show an error on the screen and begin trying to send messages again.
  2. Connection Timeout: This is the amount of Time (in seconds) that the Panel will wait before it will Retry again after receiving a Reply when trying to initiate a TCP connection.
  3. Inactivity Timeout: This value is sent to the PLC. The PLC will hold an open connection for this amount of Time. Once this Time value has expired, it will release its connection to free up resources for the PLC. If this Timer expires, the Panel will automatically create a new connection when it is ready to request Data again. This value should only need to be adjusted if many devices are communicating to the PLC and there are situations where there are long delays in requests from the Panel to the PLC (long poll times, screens with only internal objects, etc.).
  4. Response Timeout: This is the amount of Time (in milliseconds) that the Panel will wait on a Reply after sending a Request. Once the Response Timeout timer expires, it will then Retry.
  5. Poll Time: Enter a number that represents a Time (in milliseconds) that the C-more Panel will wait between executing a complete sequence of reads for the screen displayed. This setting is set to "0" by default, which produces constant polling. This setting should not require adjustment.

Connection Through Another Panel

You can configure this protocol for any PLC supported by C-more panels.

You can connect a C-more panel to other C-more panels on your network via an ethernet connection. This type of connection is also known as a Pass Through Connection.

Go to Connection Through Another Panel (Pass-Through) to learn more about Pass Through and using Connection Through Another Panel.

Troubleshooting the PLC to Panel Connection

Network Communication Errors Troubleshooting

If your network returns communication errors:

Test the basic network setup

  1. Transfer a new C-more project with Panel Manager settings that match the PLC port settings and a single Numeric Display object addressed to N7:0.
  2. Ensure that the PLC port settings are correct by verification with that PLC programming software.
  3. Power cycle the PLC, then the C-more panel.
  4. If communication errors persist, power cycle the C-more panel, then the PLC.
