FDT -
Field Device Tools
The FDT
is a software standard that allows users to communicate
with transmitters utilizing their local PC. It is supported by
most major instrumentation manufacturers, yet, surprisingly, some
users have
not yet heard of this breakthrough.
These days
most transmitters (level . flow, etc.) are smart microprocessor
based devices. They have extensive internal information and
advanced diagnostic capability that is not easily seen nor used.
Implementation of the FDT standard in transmitters basically
unleashes that advanced capability. Fortunately there is free
software out there that you can use to implement it. This approach
saves the user from having to purchase expensive and limited,
hand-held configuration devices and gives them sophisticated
troubleshooting capability from a laptop, PDA, or directly from
the control system. It works with all those brands that support
the standard regardless of communication protocol, and is
most
commonly used with HART capable instruments over a standard 4-20
mA loop.
During
this presentation Kevin will provide a live demonstration to show
how easy it is to use the FDT software to communicate with
equipment from Magnetrol and Yokogawa.
