DF1 Master Normal Poll Error

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.

• 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.

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.
