Figure 12 - Stop Sequence Template
The stop sequence is initiated by a machine STOP command via the stop logic in the R03_Control routine of
the application module. By default, the stop sequence is initiated by placing a value of 1 in the StopSEQ[0] tag.
When the StopSEQ[0] tag is set to 1, the first step in the stop sequence is executed, starting the stop sequence.
Each of the rungs in stop sequence provides a placeholder where application specific step logic can be inserted.
The stop sequence logic may include, for example, CNC commands and/or other conditional diagnostic logic.

SEQUENCE INITIATE
This rung is a placeholder where Application specific logic can be inserted.
By default, StopSEQ[0] is initially set to 1 following a Machine STOP command (that is, "MachineName".Cmd.STOP).
Refer to the Machine Commands rungs in the R03_Control routine of the Application Module.

By default, the Application is STOPPED when StopSEQ[0] reaches 999.
Refer to the Application Status rungs in the R02_Monitor routine of the Application module to modify the
conditions that detemine when the Application is STOPPED (that is, "ApplicationName".Stopped).
