Gantry Toolbox: Function Blocks
MotionWorks IEC61131-3 Toolboxes: 2013-09-13 296
PathIDManager
This function block serves as a FIFO buffer for PathID's. Each time a new PathID is created, it will delete the
memory allocated to the oldest set of CamTableIDs used for a PathID by using the Y_RemoveCamTable function
block from the PLCopenPlus firmware library. This function block cleans up memory in IEC applications which
build new paths on the fly. A circular buffer of four PathID tables is maintained in the PathIDManager. When the
function block is executed a fifth time, it releases the memory area of the oldest PathID. The controller can
allocate this memory area for new Paths or application code.
