DF1 Connection Faulted

What does I x .DF1.ConnectionFaulted mean?

This boolean tag indicates the operational status of the DF1 connection for module 'x'. When the module successfully establishes and maintains a connection, the tag value is 0. If the connection to the DF1 device is lost or was never established, this tag transitions to 1, signaling a connection failure, which can be a major or minor fault depending on controller configuration (page 77).

• Loss of physical cable connection to the DF1 slave device.
• DF1 slave device powered off or unresponsive on the network.
• Incorrect DF1 communication parameters (e.g., baud rate, parity, stop bits) configured, preventing connection establishment.

Click steps to track your progress.

1. 1

   Verify physical cable connection integrity between the DF1 module (instance 'x') and the DF1 slave device at its serial port.

2. 2

   Check power status and operational readiness of the connected DF1 slave device.

3. 3

   Review DF1 communication parameters for channel 'x' in the Logix Designer application to ensure they precisely match the DF1 slave device settings.
