__TOC__


This is change to an older version of CNC Bender LiteControl.  It is intended to update customers with older 800 x 600 screen operator stations.

===[[image:Check.jpg|25px]] New: BUILT IN SEAM DETECT LOGIC  ===

New '''seam detect logic''' uses a secondary process list that runs in parallel to the main process list.  This diagram shows main process in the orange box on the left.  This is the actual bend program process.  The box on the right is the secondary process called "seam_detect".  It runs in parallel to the main process list and causes the rotate axes to spin until the seam is located and the seam detect input is ACTIVE.<br>

==== Seam Detect OPTION ====
[[image:Seamdetect_application.jpg|300px|right]]

The new feature includes a new Seam Detect option in the PreBend option:<br>
[[image:seamdetect.jpg]]

Enable this option to include seam detection logic in the process list.
<br><br>
If enabled, the new commands for seam detection are added to the processlist between the chuck close and the run button logic.  This is a sample of what is inserted:

The new "seam_detect.cncprocesslist" is a secondary multitasking processlist that is configurable to work with the application.

===[[image:Check.jpg|25px]] TWO New Internal Commands  '''[direct_axis_jog]''' and '''[direct_axis_jog_halt]''' ===

==== [direct_axis_jog] ====

This processlist internal command will allow the process to direct-jog and axis as if a user had pressed a jog button.  Configure the command by including parameters like this:

<pre>
[direct_axis_jog] servo_controller_module_1, 2, 1
</pre>

Each parameter is separated by commas and are defined as:

#PARAMETER 1: The first parameter is the name of the module
#PARAMETER 2: The second parameter is the axis of the module (1 or 2)
#PARAMETER 3: The third parameter indicates direction.  "1" means positive jog.  "-1" means negative jog.
<br><br>

==== [direct_axis_jog_halt] ====

This processlist command uses no parameters. It halts all jog motion.

==== Sample of How Used ====

These commands can be used to move, for example, the rotate axis until a seam is detected by a device which actives an input.  Examine the "seam_detect" processlist to see how this works:

<pre>

[direct_axis_jog] servo_controller_module_1, 2, 1

[if] and, input=Input_SeamDetect_End
  // Seam detected - Disable the rotate jog now
  [direct_axis_jog_halt]
  [SECONDARY_PROCLIST] seam_detect, disable
[end]
</pre>

The jog command rotates the 2nd axis of the first servo module in the positive direction.  This is the rotate axis.  The motion continues until the seam detect input activates.  At that point the jog is halted with the second command, and the secondary processlist disables itself.
