EtherNet/IP Enable and Disable P2P Link

An XG5000 project that uses the XBL-EIPT module for EtherNet/IP will use P2P 03 or 04 for communications. P2P 03 and 04 links can be enabled or disabled from XG5000 or program code. This allows a user to safely turn off the EtherNet/IP network without having to disconnect devices or turn power off.

Requirements for EtherNet/IP Enable/Diable P2P Link:

  • XG5000 4.76 or later

  • XEM CPU OS V2.40 or later

  • XBL-EIPT OS V2.40 or later

Step Action
1

Open your XG5000 project and connect to the PLC.
2

Go to Online menu è Communication Module Setting and Diagnosis è Enable Link/Services…
3

Remove the Check mark from the P2P(EIP) Service that you want to disable. Press OK when done. This example shows P2P(EIP) 3 = P2P 03.

An XG5000 project has pre-defined variables for the status and control of the P2P links.

  • _P2P_ENABLE_STATE[x] shows the current status of the P2P link.

  • _P2P_REQ[x] is used to request a change in the P2P status using the value in _P2P_REQ_NUM[x] variable.

  • _P2P_REQ_NUM[x] = TRUE will change P2P link to enabled when _P2P_REQ[x] is set to true.

  • _P2P_REQ_NUM[x] = FALSE will change P2P link to disabled when _P2P_REQ[x] is set to true.

  • x = 2 will be P2P 03 and x=3 will be P2P 04.

XG5000 has access to the System Log of the XBL-EIPT module. This log will show when the P2P link is enabled or disabled.
