A path display can be used to visualize the bending result of the rebar bending machine. The following is an example of the application:

■ Creating a path display

■ Making Bending Parameters Block

The user is allowed to bend max 32 segments for one piece of rebar. The following table describes the memory map of bending parameters:

Bending Parameters	Segment No.	Word No.	Example(SegPar @$U100)	Remark
Length of segment	1	0	$U100
	2	2	$U102
	...	...	...
	32	62	$U162
Angle/Radius of segment	1	64	$U164
	2	66	$U166
	...	...	...
	32	126	$U226
Direction of segment	1	128.0	$U228.0	0: Clockwise 1: Counter Clockwise
	2	128.1	$U228.1
	...	...	...
	32	129.f	$U229.f
Shape of segment	1	130	$U230	0: Line 1: Arc 2: Circle
	2	132	$U232
	...	...
	32	192	$U292

■ Making Visualization Preprocess Request Block

The following table describes the memory map of visualization preprocess request block.

Word No.	Example (@$U300)	Description
0	$U300	Bit 0 1: Enable the anti-aliasing drawing feature Bit 1-15 Reserved
1	$U301	Thickness of the lines to be shown. Valid numbers: 1 to 5
2	$U302	The width of the associated Path Display
3	$U303	The height of the associated Path Display
4	$U304	0: Auto Scaling; 1: Manual Scaling;
5	$U305	The scaling ratio. The unit is one hundredth. For example, the number 200 means 200% and the number 50 means 50%. The parameter is valid when Manual Scaling is selected. Valid numbers: 30 to 300
6 to 199	$U306 to $U499	The bending parameters.

■ Obtain the bending result by using system macro command

The data required by the Path Display to show the bending result can be obtained by using the system macro command numbered 0xf105.

SYS(0xf105, P1, P2)

Macro Command Paramter	Description
P1	The starting address of the Visualization Preprocess Request Block that contains the parameters of how to generate the drawing data and the parameters of the bending operation.
P2	The starting address of the Path Definition Block that is used by the associated Path Display. The system macro command generates the drawing data according to the parameters specified in the Visualization Preprocess Request Block and saves the drawing data in the Path Definition Block.

For Example:

$u300 = 1 // Anti-aliasing

$u301 = 2 // Line thickness = 2

$u302 = 400 // Width of the associated Path Display

$u303 = 270 // Height of the associated Path Display

$u304 = 1 // Manual scaling

$u305 = 85 // Scaling ratio: 85%

$U306 = MOV($U100,194) // Save bending parameter block starting at $U100 into visualization preprocess request block starting at $U306

SYS(0xf105, $U300, $U9999) // Save the drawing data in the path definition block starting at $U9999 upon the request saved in $U300
