FB error: axis-specific PLCopen interface couldn't adopt a new request. Request FIFO full. >

Description

Jobs of axis-specific PLCopen function blocks are managed by a FIFO. The size of this FIFO is fixed (HLI_PLCO_AXIS_REQUEST_NUM). If more jobs are written to the FIFO in a PLC cycle than the space available, this error code is output to the function block whose job can no longer be sent to the motion controller.

Response

Class

-

The job is discarded by the function block and not transferred to the motion controller.

Solution

Class

-

Check if it is necessary for more jobs to be sent to the motion controller within a PLC cycle than places are available in the FIFO to solve the motion task.

Error type
