5.1 Programming
5.1.1 Programming: Overview
The following section provides information about the commands and the alarm responses of
the path object technology package. Further information is contained in the reference lists of
the technology packages.
The description of the functions for the "Toploading" standard library based on the TO path
object is contained on the "Application Toploading" function description.
5.1.2 Overview of commands
5.1.2.1 Information and conversion
Calculating the path length:
The following commands calculate the path length without starting or executing the path
motion.
The start and end points must be specified in the command.
● _getLinearPathData()
● _getCircularPathData()
● _getPolynomialPathData()
Geometric path analysis:
The commands listed below are used to calculate Cartesian path data, such as path
direction and path curvature, at the start point, endpoint, and a specifiable point on the path
without starting or executing the path motion.
The point on the path is specified by means of the default setting of the path length distance
to the start point.
The start point is specified in the command, as is the position with reference to the path
length where the information data is determined.
● _getLinearPathGeometricData()
● _getCircularPathGeometricData()
● _getPolynomialPathGeometricData()
