How to display overlap parts from the PLC (external)

There are four overlap part types.

• Normal overlap
• Call-overlap
• Multi overlap
• Global overlap

In the case of external commands, the display method differs.
 

[Normal/call overlap]
Two methods are available.

<Using the read area>

The overlap part will be displayed when bit 0 to 2 of read area "n + 1" corresponding to the desired overlap ID number is turned ON.

<Using the control device memory>

Check [Control Device] in the [Overlap] dialog on the V-SFT-6 editor.
The overlap part will be displayed when bit 0 of the specified cotrol device memory is turned ON.

Example: Normal overlap

[Multi/Global overlap]
Two methods are available.

<Using the read area>

1. Display the [Overlap] dialog or select [System Setting] → [Global Setting] → [Global Overlap Setting], and select [Display Method: Control Device] on the V-SFT-6 editor.
   Set the PLC device memory for [Info Output Device].
   A device memory address is set for [Device Overlap Library No. to Display] (= information output device "n + 1").
   (The overlap library number to be displayed is stored in this device memory address.)
   
   Example: Multi-overlap
   
   
   Contents of info output device

   Device	Contents	Operation
   n	The overlap library number of the multi/global overlap part currently displayed on the screen is stored. When no overlap display is shown, "-1" is stored.	V/TS→PLC
   n+1	Specify the overlap library number to be displayed.	V/TS ← PLC
   n+2 *	Specify the X coordinate of the multi/global overlap display.	V/TS ← PLC
   n+3 *	Specify the Y coordinate of the multi/global overlap display.	V/TS ← PLC

   * Valid when the [Specify the display position by device] is checked.
    

2. The overlap part will be displayed when the bit of read area "n + 1" corresponding to the desired overlap ID number is turned ON.
   - Multi overlap: Bit 0 to 2 of read area "n + 1"
   - Global overlap: Bit 3 of read area "n + 1"

<Using the control device memory>

1. Display the [Overlap] dialog or select [System Setting] → [Global Setting] → [Global Overlap Setting], and select [Display Method: Control Device] on the V-SFT-6 editor.
   Set the PLC device memory for [Info Output Device].
2. Check [Control Device].
3. A device memory address is set for [Device Overlap Library No. to Display] (= information output device "n + 1").
   (The overlap library number to be displayed is stored in this device memory address.)
   
   Example: Multi-overlap
   * For more information of the Info Output Device, refer to the "Contents of info output device" above.
    
4. The overlap part will be displayed when the number to display is set for [Device Overlap Library No. to Display] set in step (1) and bit 0 of the control device memory is turned ON.
