Will FDI answer every issue of all the users of fieldbus device management tools? Not quite. A few areas cannot be simply answered by a specification or standardization. Problem issues may include procuring and installing the tool, non-intuitive tools, inadequate or overly complex tools, and inflexible and non-scalable tools.
The first step sometimes becomes the most time consuming step. Many tools have a heavy footprint that makes them time consuming to download and install. Many tools have .NET and/or SQL as pre-requisites, increasing installation time.
Additionally, the device drivers must be installed or imported, and updated to the latest version. Additional steps include installing & configuring the modem driver, which varies from vendor to vendor. Then most tools need a manual catalog update. Some tools require the enabling or activation of license. Lastly a few more clicks enable communication, scan, or go-live with the device.
Often, the user just wants to configure the same basic parameters (for example Tag, Range, Unit) or execute the same parameters or functions such as zero settings over and over again. Most tools do not support such tasks. Even if they do, many steps may be involved, increasing user frustration.
Additionally a massive amount of information may be dumped on the screen in unfamiliar colors and icons, which vary widely from tool to tool. One option is to choose the standardized status indicators as prescribed by NAMUR.
