STOP example

DescriptionX := 505, DescriptionY := 505, DescriptionWidth := 0)
END_STOP
Entering Branches
The branch blocks in an SFC routine identify simultaneous or
selection branches in the routine. Branches follow this format:
BRANCH (
ID := <
unique_identifier >,
Y := <
internal_grid_y_location >,
BranchType := <
text >,
BranchFlow := <
text >,
Priority := <
text >)
<LEG_block>
END_BRANCH
Item: Identifies:
ID
the stop identifier. This ID uniquely identifies this stop from all other blocks. Enter an
unsigned, 32-bit integer value.
Specify:
ID := number
X
x-coordinate on internal grid. Enter an unsigned, 32-bit integer value.
Specify:
X := number
Y
y-coordinate on internal grid. Enter an unsigned, 32-bit integer value.
Specify:
Y := number
Operand
the stop tag. Enter a tag of datatype SFC_STOP. The import process uses this tag name to
name the stop.
Specify:
Operand := tag
HideDescription
whether or not to hide the stop description. Enter Yes or No.
Specify: HideDescription := text
DescriptionX
x-coordinate on internal grid of the description box. Enter an unsigned, 32-bit integer
value.
Specify:
DescriptionX := number
DescriptionY
y-coordinate on internal grid of the description box. Enter unsigned, 32-bit integer value.
Specify:
DescriptionY := number
DescriptionWidth
this attribute is not currently used; it is there for future use. Enter 0.
Specify:
DescriptionWidth := 0
