Pc Software For The Dmt-1000 - OHIO SEMITRONICS DMT-1000 Mode D'emploi

7.2 PC software for the DMT-1000

The DMT-1000 transducer is equipped as standard with
both an RS 232C interface and an RS 485 MODBUS interface.
The latter permits up to 32 devices to be connected including
a master (PC).
Accordingly, two program packages are available for
the DMT-1000, "DMT-Config" and "MRS-1000 Software".
"DMT-Config" provides functions for both interfaces. For
example, the existing configuration of a transducer can be
simply adapted to changed measurement requirements,
measurements and counter readings can be uploaded and
other functions for specific devices executed.
The PC is connected to the RS 232 interface by the
programming cable. In the case of an RS 485 interface, a
converter RS 232C ⁄ RS 485 is needed which can be either a
board in the PC or an external unit.
The software has an easy-to-operate, clear menu structure
which allows for the following functions to be performed:
• Uploading and display of the programmed configuration of
the transducer or, in the case of the RS 485, the addressed
device
• Easy change of input and output parameters
Fig. 12. Overview of the parameters.
• Downloading of a modified or new configuration to the
(addressed) transducer
• Archiving of configuration files
• Configurable password access to those functions that
permit transducer data to be changed
• Configuration of all the usual methods of connection
(types of power system)

• Selection of the measured variables for up to 4 internal
counters
• Provision for resetting the maximum value detectors of
output and bus variables (RS 485 only)
• Provision for frequency measurement using either voltage
or current
• Definition of the measured variables on the bus to be
uploaded via the MODBUS interface (RS 485) together
with the device address and the data transfer parameters.

• Measurements displayed: Analog output signals
(RS 232) and all measured variables selected on the
transducer that has been addressed
• Power system check: Display of all the system values,
ideal as a wiring check (RS 232 only)
• The simulation of the analogue outputs for test purposes
(RS 232 only)
• Printing of nameplates.
