Special Scripting Considerations for the EPM 7700

This section describes the special InTouch scripting which is required for the EPM 7700 device’s Large Faceplate, Tabular Data Screen, and Custom Tabular wizards. The EPM 7700 is a powerful and highly flexible device, supporting hundreds of discrete data items. This scripting is required due to the large number of DDE items available for this device type. For performance reasons, not all DDE items are kept active simultaneously by the EPM 7700 Tabular Data Screen wizard; at any given moment, DDE items which are not used may be disconnected to save the Server the additional overhead of monitoring unused items. The scripts described in this section automatically configure the DDE links used by the Tabular Data Screen wizard when it is displayed, and enable the Large Faceplate wizard to re-connect to items which may have been disabled by the Tabular Data Screen wizard.

NOTE: Failure to install these scripts for the Large Faceplate and Tabular Data

Screen wizards may result in faulty behavior of the wizard!

Templates for the required scripts are automatically installed in the InTouch directory when PMCS is installed with the EPM 7700 Software Components option selected. You may use the Notepad accessory program to open the files, then copy the text from the file to InTouch when appropriate.

There are three scripts described in this section. The first script is an InTouch Application Script that is required whenever a Large Faceplate or Tabular Data Screen wizard is installed for a given device. The purpose of this script is to provide communication status indication on the wizard. If the application script is not installed, the “Communications Failed” indicator on the Large Faceplate and Tabular Data wizards will not function. The second script, the EPM 7700 Large Faceplate/Custom Table Script, is an InTouch Window Script that must be applied to each Large Faceplate and Custom Tabular wizard window. This script ensures that any tags which were disabled by the Tabular Data wizard are properly restored when switching to a Large Faceplate or Custom Table screen. The third script, the Tabular Data Screen Script, also an InTouch Window Script, applies only to the EPM 7700 Tabular Data Screen wizard. Its purpose is to automatically initialize the wizard for optimum performance whenever its window is displayed.

Note that the application script is required whenever a Large Faceplate or Tabular wizard is installed. The Windows scripts are required whenever your application uses Tabular Data wizards.
