APS: No memory block available for job processing in %x for function %d.

What does 896 mean?

A request for memory space, specifically for the internal management list, could not be satisfied, preventing the called function (%d) from executing. This is often caused by frequent loading of client modules that are waiting for a response from the NC, leading to resource exhaustion. This is a PLC error with no error recovery possible.

• Request for memory space for internal management list could not be satisfied.
• Called function could not be performed due to memory shortage.
• Frequent loading of client modules waiting for NC response.

Click steps to track your progress.

1. 1

   Verify current firmware version of the Bosch Rexroth Motion Control unit and check for available updates.

2. 2

   Inspect the loaded PLC/NC application program configuration, focusing on client module communication parameters (e.g., cycle times, buffer sizes, timeout values) and potential excessive resource allocation.

3. 3

   Monitor NC/PLC system resource utilization (CPU load, memory usage, communication buffers) using integrated diagnostic tools to identify persistent high usage or leaks.

4. 4

   Analyze the behavior of external client modules or connected systems to determine if they are initiating an unusually high frequency or volume of requests to the NC.
