Cam Toolbox: Function Blocks
MotionWorks IEC61131-3 Toolboxes: 2013-09-13 135
CamTableManager
This function block serves as a FIFO buffer for CamTableID's. Each time a new CamTableID is created, it will
delete the memory allocated to the oldest CamTable by using the Y_RemoveCamTable function block from the
PLCopenPlus firmware library. This function block is used to clean up memory in applications which build cam
tables on the fly. A circular buffer of four cam tables is maintained in the CamTableManager. When the function
block is executed a fifth time, it releases the memory area of the oldest cam table ID. The controller can allocate
this memory area for new cam tables or application code.
