Process Trend ActiveX Control

Installation

Introduction

The installation uses two install files, which can be downloaded here:

ProcessIT_TrendOCX.msi Microsoft Installer Package (Executable). This installs the Process Trend OCX itself (ProcessTrend.OCX) along with a number of supporting files	Download
FlpGrfRT.exe Flipper Graph Runtime Installer. This installs and registers the Flipper OCX, which provides the main graphing (drawing) functionality	Download

Dependencies

The Process Trend OCX is dependent on a number of files for correct operation. The following components will be installed by either the ProcessIT_TrendOCX.msi or FlpGrfRT.exe installation utilities:

Visual Basic Runtime
Microsoft Common Controls
Microsoft XML 3 Parser
FloatingPoint.DLL
IniFileInterface.DLL
Flipper Graph OCX
Trend Definition File (ProcessTrend.XML)

In addition, the Process Trend OCX uses the following file:

PHD OLE Automation Object (Visual PHD DLL)

The Visual PHD DLL is usually installed as part of the PHD Desktop. It is not included in either the ProcessIT_TrendOCX.msi or FlpGrfRT.exe install files.

The Trend OCX does not require the other components and applications that are installed with the standard installation of the PHD Desktop, so these may be deleted if not required by other applications.

Installation Procedure

Ensure you are logged on as Administrator.

The order in which the executable files are run is not critical, however the following procedure is recommended:

Run FlpGrfRT.EXE to install the Flipper Run Time
Run ProcessIT_TrendOCX.msi to install the Trend OCX

Running the Trend OCX

Two HTML files are included with the download:

trend.htm
This uses the Trend OCX to connect to an existing PHD historian
trendSim.htm
This connects to the Visual PHD Emulator

trend.htm
If connecting to PHD, you will need to modify the HTML file to use the correct name of the PHD server, as indicated below in red. You may also need to modify the user name and password, but in most cases the the default PHD_READONLY will work.
