IFIX and Terminal Services

Introduction

iFix is a SCADA (System Control and Data Acquisition) software. It was developed by Intellution and is now part of the GE Fanuc Proficy series of industrial software.
This Wiki Article is a simplified deployment guide for ThinManager users. Although it was prepared with the help of iFix users and specialists, it is a mere aid and not the definitive source for information. Please refer to official iFix documentation for questions and details.

Network Configuration

IFix is designed to pull data out of PLCs and factory-level sensors, present the data in a form usable by humans, and save the data for further usage. iFix is designed to function with a “two-box” system.

• The first box is a SCADA (Systems Control And Data Acquisition) computer. This is a PC that gathers the I/O and data from the PLCs and machinery and runs the iFix database. This computer provides the data and values to the system.
• The second box is a View Node. This is a computer that pulls the data from the SCADA node and displays it on screens for the operator.

In a terminal services environment the terminal server acts as the View node. Each client that connects to a terminal server will start a session and launch a view node within the session. The sessions on the terminal server run the operator screens populated with data from the SCADA node.

Sample iFix Network with Thin Clients

In a ThinManager system dual terminal servers can be setup to provide redundancy and failover. This allows the operator screens to keep running with current data if a terminal server fails.

Deployment Choices

How iFix will be deployed and used influences how iFix is

• Generic Deployment Model– All users use a common SCU file to launch a commonly configured application.
• Specialized Deployment Model – Each user runs a unique environment and each user requires a specially configured SCU file.

This article will assume a generic deployment but will point out where changes need to be made to deploy a specialized configuration.
The generic deployment can be designed to launch a Main Menu with navigational buttons to allow the user to select the needed screens or the welcome screen can have scripts added that launch the desired screens based on the node name of the client.
Consult your iFix documentation for details.

Microsoft Pre-planning

There are a few configuration changes that iFix may require on the Microsoft operating system, especially if legacy applications are needed to be upgraded to run on the new system. Consult your iFix documentation for details.

Relaxed Security

IFix requires the Relaxed Security setting. This can be applied by opening the Terminal Services Configuration console by selecting Start > Programs > Administrative Tools > Terminal Services Configuration. Select the Server Setting folder and change the Permission Compatibility setting to Relaxed Security.

Terminal Services Configuration – Server Settings

Disable DEP (Data Execution and Prevention)

The DEP may need to be disabled for the terminal server to recognize USB license keys. The iFix documentation says:

“iFIX Does Not Start After Install Due to DEP Access Restriction (Proficy HMI/SCADA – iFIX Release Notes   VERSION 4.0)
“When you start iKeyDiag or iFIX 4.0 for the the first time, an access violation may occur. You will not be able to start iFIX. This can occur due to hardware enforced DEP (Data Execution Protection) settings within Windows Server 2003 SP1 or Window XP SP2. To remedy this issue, you can selectively add the iFIX program to the DEP exception list or shut down the feature. iFIX will then run normally. For more information, refer to "DEP Support Statement For GE Fanuc Products Using Proficy Common Licensing" article on the GlobalCare site for more information:

Right Click on the My Computer Icon and choose Properties. Select the Advanced tab, then the Settings button in the Startup and Recovery section. Select the (manual) Edit button on the Startup and Recovery Properties Window.
Set the bootloader information to:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows Server 2003, Standard" /fastdetect /NoExecute=alwaysoff

Application Compatibility Script

The following information is from the iFix e-books under Installing and Configuring iFIX with Windows Terminal Server. Also as a separate Document, it can be found at:
C:\Program Files\GE Fanuc\ProficyDoc\1033\iFIX\TM.CHM
Before you begin installing and configuring iFIX on a Terminal Server, it is recommended that you complete the following Windows administrative tasks:

• Run chkroot.cmd from the C:\Windows\Application Compatibility Script folder. This creates the RootDrv2.cmd file.
• In Notepad or another text editor, open the RootDrv2.cmd file from the C:\Windows\Application Compatibility Script folder. At the end of the file, on the Set RootDrive= line, add a driver letter. For example: Set RootDrive=W:
• Save the RootDrv2.cmd file.
• Run the RootDrv2.cmd file.
• Verify that your Terminal Server is set up and functioning.
