Secondary Processlist

A secondary processlist is a multitasking list of commands to move devices that surround the main bender motion. CNC Processor allows for any number of secondary processlists to run during the main cycle.

Our CNC Bender software is the only bender software in the world that we know of that allows for secondary processes like this. This adds extreme flexibility and power to the bending cell.

This is secondary processlist that controls an autoloader. This process runs independently of the main bending process as long as CYCLE START is active:

// ** AutoLoader Loader Process List **

// Open the grippers and return the loader

  AutoLoader_GripperOpen
  WaitForHopperPartClear = cto:10000

// ----------------------------------------------
// Decrease the priority of this list now
// ----------------------------------------------


  [DISPLAY] LOADER - Decrease Priority of Secondary List 1 (0.250 secs)

// ----------------------------------------------
// CHECK FOR END CYCLE
// ----------------------------------------------


  [DISPLAY] LOADER - Wait if END CYCLE
  WaitForIBR_NotEndCycle

  AutoLoader_GripperClose

  
// ----------------------------------------------
// Increase the priority of this list now

// ----------------------------------------------
// Increase the priority of this list to high priority
// ----------------------------------------------


  [DISPLAY] Loader - Increase Priority of Loader Process (0.025 secs)
  [SECONDARY_PROCLIST_INTERVAL] AutoLoader_Loader, 25

  
// ----------------------------------------------
// Move the Loader Arm to the bender
