At a Glance

Two sections are declared in the MAST task:

The Labelling_Program section (See Creating the Labelling Program in ST), written in ST, initiates and uses the Modulo Loop Counter Mode functions and I/O objects,
The Application section (See Creating a Program in LD for Application Execution), written in LD, executes the counting start-up and the operator screen animation.

Process Chart

The following screen shows the process chart.

Description of the Labelling _Program Section

The following table describes the different steps of the process chart.

Step	Description
Functions enabling	Enables the Modulo Mode functions used in the application.
Threshold definitions	The values of the thresholds, on which depend the reflex outputs, are defined in this step.
Process deflection	Test if the capture value is greater than the deflection parameter
Deflection Alarm ON	If the result of the process deflection test is true, the alarm is ON.
Deflection Alarm OFF	If the result of the process deflection test is false, the alarm is OFF.
