This boolean tag for DF1 Master module 'x' indicates that an error occurred during a priority polling cycle. A value of 1 signifies that the priority poll did not complete successfully, potentially disrupting critical, time-sensitive data exchange with a high-priority slave device.
Click steps to track your progress.
Verify the configured address of the Priority Poll Node (e.g., in the `Ox.DF1Master.PriorityPollNode` array) matches the physical address of the slave device.
Check communication settings for DF1 Master channel 'x', including baud rate, parity, and stop bits, to ensure they match all connected slave devices.
Ensure the priority slave device is powered, operational, and properly connected to the DF1 network.
Measure signal integrity on the DF1 bus for channel 'x' to detect excessive noise or signal degradation.
