SPECIAL SECTION which is created by the instrument sup- plier, who has the most knowledge of the full ca pability of the device. DTMs can range from a simple graphical user in - terface for setting device parameters to a highly sophisticated application that can perform complex calculations for diag - nostics and maintenance. They include a user-friendly graphical interface to sim - plify device configuration, maintenance, and troubleshooting. Their simple and clear interface standardizes the train - ing required to configure an intelligent field device—shortening setup time and reducing configuration errors. Conversely, the FDT/FRAME provides access to all devices, gateways, and com- munication components with single-point access to operational assets. It can be em- bedded in any control system, configura- tion tool, or engineering application that needs seamless access to the installed base of intelligent devices. This component al- lows DTMs to extract performance-driven data from all connected devices and multi- plexers on a control network. Inter Pipeline used FDT/DTMs to en- sure field devices were precommissioned and configured properly. Device manufac- turers provide FDT/DTM software for their products, and the FDT/FRAME communi- cates and reads those DTMs—regardless of protocol—for each device. This enables complete life-cycle access for configura- tion, operation, and maintenance, no mat- ter the supplier, device type/function, or communication protocol. Inter Pipeline monitored and trouble- shooted multivendor instruments at the Pioneer 2 facility using PACTware soft- ware. An open-source program available to members of the PACTware Consor- tium, PACTware functions as a frame or "container" application that instantiates DTM driver objects (including display- ing the device user interfaces) and allows connections between them. It is intended for flexible parameter adjustment of field instruments, remote I/O, and commu- nication modules in digital bus systems and networks. It supports integration and interoperability capabilities that allow us- ers to operate field devices from different manufacturers and communication pro- tocols with a single, standard PC-based application. PACTware is a simple solution for de- vice configuration, and at the same time, it provides a path from basic applica - tions to complex asset management. The incorporation of .NET technology not only enables greater independence from the hardware platform, but it also opens up new opportunities for a more advanced graphical user interface. Addressing instrument failures Inter Pipeline instrument technicians integrated DTMs with PACTware soft - ware to investigate, analyze, and correct instrument failures. In doing so, they eliminated spurious trips during startup of the Pioneer 2 facility. According to Shah, personnel at the Pioneer 2 facility found that using DTMs did not require a high level of technology expertise, but rather provided graphical access to smart device measurements and diagnostics for quick problem identification and resolution. "Device DTMs proved to be valuable when configuring and trouble - shooting complex instruments like radar and magnetic level gauges," Shah said. "Technicians were able to see the devices clearly, know their condition in advance, and act with agility throughout their workflows." DTMs support a more robust diagnos- tic capability than Device Descriptions (DDs) and Electronic Device Description Language (EDDL), which provide mini- mal information on how to address mal- functions and configuration issues with smart instrumentation. The DTMs are a handy tool for less experienced techni- cians to solve instrument problems in a short time. Device suppliers can embed intelli- gence in a DTM in a way that is very dif- ficult to accomplish with DD files, such as graphical constructs that cannot be expressed within DD technology. More- over, the DTM is specific to the device and revision, so it has knowledge about the particular version of each device on the control network. For example, mag- netic level gauges installed at the Pio- neer 2 plant have a DTM interface with a user-friendly troubleshooting menu. Be- ing able to set sensitivity values through the intuitive DTMs helped resolve device performance issues and allowed person- nel to do remote configuration, trending, and diagnostics. In another instance, guided wave radar instruments had problems during tank filling. Personnel could adjust signal sup- pression and other parameters via DTMs. They gained visualization of echo curves, trends, and vessel configuration, along with the ability to store, review, save and email data on instrument configuration.
