iFIX uses a number of directories to store program and data files. Use the Path Configuration dialog box to specify the location and names of your iFIX directories. You can display this dialog box by clicking the Path button on the SCU toolbox.
When iFIX is installed it creates a directory, called the Base directory, and all the subdirectories you see listed in the Path Configuration dialog box. If you decide to change the Base path, and the other directories are subdirectories of the Base path, click Change Base to automatically update all the listed directory names. When you change a path the SCU creates the new directory for you. However, it does not copy the files from the old directory to the new directory.
NOTE: When configuring paths for your iFIX components, it may be helpful to place some directories on the local machine and some on a network server. For example, keeping your Local and Database directories on a local path name allows you easy accessibility on your computer, whereas copying the Picture and Historical files to a network server enables anyone on the network to access these files to view a picture, historical data, and so forth.
The table below describes the use of each directory.
|
The path... |
Is used for storing... |
Default Path |
|
Base |
All executable files. The Base path points to the main iFIX directory. Other directories are usually subdirectories of the Base directory. |
C:\Program Files (x86)\Proficy\iFIX |
|
Language |
The language files used to create dialog boxes and help files. If you choose to implement a language other than English, the new language and help files replace the files found in this directory. |
C:\Program Files (x86)\Proficy\iFIX\NLS |
|
Local |
Configuration files associated with the local computer, including SCU, recipe format, and system security files. |
C:\Program Files (x86)\Proficy\iFIX\LOCAL |
|
Project |
A grouping of application files, such as pictures, databases, and tag groups, saved in a specific folder identified by the project name. You can manage your application files by naming a different path for each project. |
C:\Program Files (x86)\Proficy\iFIX |
|
Database |
Process database files, Database Manager configuration files, and I/O driver configuration files. |
C:\Program Files (x86)\Proficy\iFIX\PDB |
|
Picture |
The pictures of the configuration and run-time environments. NOTE: If you are using a shared PIC directory on a drive other than the one on which iFIX is installed, you must enter the full path to the PIC directory. For example, if you want to use a shared PIC directory on the G:\ drive, you must enter G:\PIC in the SCU If you want to allow multiple clients to open the same picture file past the Windows concurrent limit, you need to make sure that the PIC folder on your iFIX Server is set to read-only and that the pictures in that folder are also read-only. Additionally, the following entry needs to be added to FixUserPreferecnes.ini: [FileOpenMethod] FileOpenStyle=1 The limit of 20 concurrent users opening a file at one time is a Microsoft limitation when using the IStorage object. This limitation is documented in the Microsoft online reference for the IStorage object, located here: http://msdn.microsoft.com/en-us/library/windows/desktop/aa380364%28v=vs.85%29.aspx. |
C:\Program Files (x86)\Proficy\iFIX\PIC |
|
Application |
Data and configuration files for your iFIX applications. If you create your own applications, use this directory to store data files. |
C:\Program Files (x86)\Proficy\iFIX\APP |
|
Historical |
Historical Trending configuration files. |
C:\Program Files (x86)\Proficy\iFIX\HTR |
|
Historical Data |
Historical data files. Historical Trending creates a unique subdirectory to this directory for each node that data is being collected from. The subdirectory uses the name of the node the data comes from. |
C:\Program Files (x86)\Proficy\iFIX\HTRDATA |
|
Alarms |
Alarm data files and event log. NOTE: If you want to view an event log (.evt), make sure that you associate an editor such as Notepad with the .evt file type so that you can open and read the file. If you do not, when you double-click the .evt file, an error may appear. |
C:\Program Files (x86)\Proficy\iFIX\ALM |
|
Master Recipe |
Master recipe, master recipe error, and master recipe report files. |
C:\Program Files (x86)\Proficy\iFIX\RCM |

Control recipe, control recipe error, and control recipe report files. |
C:\Program Files (x86)\Proficy\iFIX\RCC |
