Advance Instrument Functions
The Advance Instrument Functions consist of the ability to review the process variable data of each sensor element channel, in a multi-point instru-
ment. The data is not a continuous read but a one shot read, when the block is open. In order to update the values of the channels the read button
needs to be pressed. The instrument has the ability to show data of up to 16 sensor elements.
Device Description Files
General DD FILES
The DD files are device support files that include two device description files, and one capability files. DDs are platform and operating system
independent.
The DD provides an extended description of each object in the Virtual Field Device (VFD).
The DD provides information needed for a control system or host to understand the meaning of the data in the VFD including the human interface for
functions such as calibration and diagnostics. Thus, the DD can be thought of as a “driver” for the device.
The ST100 DD files are found under a file folder labeled “01FC49”, and subfolder 0001:
0101.ffo
0101.sym
010101.cff
