About Setpoint/Span Settings
You can also define a different setpoint and span to be used while the external
command process plays out.
You should understand how setpoint and span settings on the different Station
Manager and MPT windows affect one another.
• Scaling tab External Command Parameters window, MPT application.
The Change Setpoints and Change Spans check boxes let you override the
system setpoint and span values while the process is being run.
• Setpoint and Span window, Station Manager application.
This window contains the system setpoint (Setpoint slider) and span (Span
slider) values that the External Command process overrides while the
process is being run.
• Command Options tab, Channel Options window, Station Manager
application.
The value in the Setpoint entry box determines the default rate at which the
controller ramps to the setpoint value entered in the External Command
Parameters window. Likewise, the Begin control determines the rate at
which the controller ramps the external program to the span value entered in
the External Command Parameters window.
• Execution tab, MPT Options Editor, Span and Setpoint controls, MPT
application.
The Span and Setpoint controls determine whether you can edit the setpoint
and span values entered in the Station Manager Span and Setpoint window
while the External Command process is being run.
