6.4 Starting and Stopping a Loaded Project
Once a project is loaded onto the Pointe Controller unit, it’s a very easy matter to
start the project:
1. Verify that PCM is attached to the target controller and your project is
loaded onto it.
2. From the Execution mode drop-down menu, select either I/O Enabled
or I/O Disabled:
In I/O Enabled mode, the controller will scan all I/O points and
execute charts using live data. This option is intended for real control
of connected machinery.
In I/O Disabled mode, the controller will not scan any I/O points and
will only execute charts internally using virtual data. This option is
useful for debugging logic flow; inputs can be simulated by
forcing
tag values .
3. Click the Start button.
When the project is running, you can proceed with monitoring and/or debugging
it.
6.4.1 Stopping a project
To stop a project that is currently running on an attached controller, simply click
the Stop button. The controller immediately stops scanning charts and I/O, and
the project’s last state (including tag values and chart conditions) is retained in
memory.
WARNING : Stopping a project does not stop the controller’s internal clock nor
any Timers that are keyed to it. Active Timers continue to count elapsed time
even while the project is stopped, and all control logic that is based on those
Timers will update accordingly when the project is resumed.
To completely stop an active Timer, you must either execute a Timer Stop
command (T_STOP) within the project or stop and reset the project using PCM.
For more information on resetting a project, see below.
6.4.2 Restarting a stopped project
To resume a stopped project from its last state, simply click the Start button
again.
To restart a stopped project from its initial state – that is, the initial tag values
and chart conditions that you defined when you created the project in the
PointeControl Framework – click the Reset button and then the Start button.
