I x .DF1Master.NormalPollError

DF1 Master Normal Poll Error

Allen-Bradley · Compact 5000 I/O Serial Module

What does I x .DF1Master.NormalPollError mean?

This boolean tag for DF1 Master module 'x' indicates that an error occurred during a normal polling cycle. A value of 1 signifies that the normal poll did not complete successfully, affecting routine data acquisition from standard slave devices on the DF1 network.

Common Causes

  • No response received from the polled normal node within the configured communication timeout period.
  • Invalid or malformed response received from the normal node.
  • Communication interference or excessive noise on the DF1 channel preventing reliable data transmission.
  • Normal slave device address configured incorrectly or not powered on.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Verify the configured address of the Normal Poll Node (e.g., in the `Ox.DF1Master.NormalPollNode` array) matches the physical address of the slave device.

  2. 2

    Check communication settings for DF1 Master channel 'x', including baud rate, parity, and stop bits, to ensure they match all connected slave devices.

  3. 3

    Ensure the normal slave device is powered, operational, and properly connected to the DF1 network.

  4. 4

    Measure signal integrity on the DF1 bus for channel 'x' to detect excessive noise or signal degradation.
