Firmware use only

Was bedeutet ERR_BUFFER_ALLOC ?

This error is for firmware internal use only, indicating a failure to allocate a buffer. This suggests a memory exhaustion issue within the controller for Modbus TCP operations, preventing the processing of new data.

• Insufficient free memory in the controller to handle Modbus TCP communication buffers.
• Memory fragmentation due to long-term operation or other applications consuming resources.
• Excessive data transfer sizes requiring large buffer allocations.

1. 1

   Reduce the number of active Modbus TCP connections or the size of data transfers.

2. 2

   Review other running applications in the controller that may consume excessive memory.

3. 3

   Restart the controller to free up fragmented memory and available buffers.
