Receive Buffer Full

What does F222 mean?

The receive buffer has no free area, indicating a buffer-full error that prevents further data reception. This can happen due to high communication traffic or issues with the sending CPU's receive processing.

• High volume of transient communication overwhelming the receive buffer
• Short communication intervals leading to buffer overflow
• Sending destination CPU error (e.g., issues with receive processing or END processing)

Click steps to track your progress.

1. 1

   Attempt to retry the operation after a short interval

2. 2

   If the error recurs, review the system's transient communication times and communication interval settings to reduce traffic

3. 3

   Investigate the sending destination CPU for errors related to receive processing
