The Control Program
The Control Program (Details)

The control program, which is often referred to as the Program or PGM File, includes the user's list of time-precise Control Commands. The purpose of a control program is the automatic and repeated execution of specific routine tasks, such as processing samples automatically or conditioning a column by rinsing with various solvents. In addition, the control program allows monitoring certain parameters or limits, or triggering reactions when these limits are exceeded.

A Wizard (see  Program Wizard) assists you in creating a program by automatically converting your entries into the appropriate Chromeleon program commands. In this way, you can create a program even if you do not know the command syntax.

To edit an existing program, double-click the program name in the Browser to open the program in the most recently used view of the PGM Editor (see Control  The PGM Editor).

To edit the control settings for a device, click the associated device icon on the left pane. This view provides the corresponding pages of the Program Wizard. Enter new parameters or change existing parameters according to your requirements.

 Tip: 

Dionex recommends always editing programs in the associated Device view. The Device view is easy to use and ensures correct command syntax. Use the  Commands view only if the desired parameters are unavailable in the device view.

 Tip: 

Similar to a control panel, you can edit a PGM File only if it is connected with a Timebase while the server is running. Therefore, verify that the server is running. Start the server in the Chromeleon Monitor Program if necessary. To connect the PGM File with a timebase, select Connect to Timebase on the Control menu.

If the PGM File is correctly connected with a timebase, icons for all devices in that timebase are provided, allowing you to access the associated PGM Wizard pages.
