Firmware use only

Was bedeutet ERR_QUE_FULL ?

This error is for firmware internal use only, indicating an internal queue is full. This suggests an overload condition within the controller's Modbus TCP processing, where incoming requests are exceeding the system's ability to process them.

• High volume of Modbus TCP requests overwhelming the controller's processing capacity.
• Slow response from the Modbus TCP application logic causing queue buildup.
• Insufficient internal buffer size for handling peak traffic.

1. 1

   Reduce the rate and frequency of Modbus TCP requests sent to the controller.

2. 2

   Optimize the controller's application logic handling Modbus TCP requests to improve processing speed.

3. 3

   Restart the controller to clear any transient queue overload conditions.
