ST100 Series Profibus PA
18 Fluid Components International LLC
Basic Instrument Setup
The ST100 PROFIBUS PA comes with two GSD files, the profile version (pa139760.gsd) and the manufacturer specific file
(01000E00.GSD). It is recommended that the FCI manufacturer specific file be used. This file gives the user access to the
maximum number of process variables the ST100 instrument has to offer.
To set the PROFIBUS PA address; a class 1 master or a class 2 master is required. The function of either the class 1 or class 2
master may be used to set the address.
For basic system configuration, the AI blocks have been preset to their specific variable channels. Other parameters in the AI
block have been set to defaults.
Review of Instrument Min/Max Settings
The Flow Calibrated range is delimited by the MIN and MAX values set by the factory. Flow values outside of the range are not
guarantied to meet the accuracy specification. These parameters are read only, and can not be changed by the user.
Advance instrument functions
For multi-point systems the “SENSORS_BANK_1” parameter can be use to view the process parameters for individual sensor
elements. “SENSORS_BANK_1” supports the first 4 sensor parameters; the information is presented as floating values. The
structure repeats for each bank. Only bank 1 is active.
Flow Value Sensor #1 Temperature Value Sensor #1 Pressure Value Sensor #1
Flow Value Sensor #2 Temperature Value Sensor #2 Pressure Value Sensor #2
Flow Value Sensor #3 Temperature Value Sensor #3 Pressure Value Sensor #3
Flow Value Sensor #4 Temperature Value Sensor #4 Pressure Value Sensor #4
General Station Description Files
GSD Files
The GSD files describe the communication features of the device, they also allow easy configuration of PROFIBUS networks with devices from
different manufacturers. The GSD files can be thought as “driver” files for the device.
There are two GSD files provided in the accompanying CDROM. The first is the Profile 3 specific file created by the PNO; which is the International
PROFIBUS Organization, and all profile compliant instrument must meet. The second file is a FCI specific GSD file. This file supports features that are
unique to the ST100 Flowmeter.
The GSD files contain the definitions of faults, and the type of process parameters available for display.
The PROFIBUS GSD Files for the ST100 are the following:
Profile Specific File: pa139760.gsd
FCI Specific File: 01000E00.gsd
