SoftLogix 5800 Connection Notes

For proper operation, no Ethernet-based drivers (such as ethernet devices, remote devices via Gateway, and so forth) should be installed in RSLinx on the SoftLogix PC. With one or more Ethernet-based drivers installed, requests will return with CIP Error 0x5 Ext. Error 0x1 and CIP Error 0x8.

Connecting to a SoftLogix Soft PLC on the Same PC as the OPC Server

To connect the Allen-Bradley ControlLogix Ethernet Driver to a SoftLogix Soft PLC running on the same PC as the server, follow the instructions below.

  • 1.

    Ensure that there are no Ethernet-based drivers currently running in RSLinx on the PC.

  • 2.

    Verify that the Ethernet/IP Message Module is installed in the SoftLogix virtual chassis.

  • 3.

    Open the server's Device Propeties. In the General tab, locate the Device ID value. It should not be
