6.2 PC software for the EURAX DME 440

EURAX DME 440 transducer is equipped as standard with
both an RS 232C interface and an RS 485 MODBUS inter-
face. The latter permits up to 32 devices to be connected
including a master (PC).
The program packages "PC Software DME 4" (Order
No. 146 557) is available.
"PC Software DME 4" 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 pro-
gramming cable (Order No. 980 179), 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. 9. 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)
• Provision for configuring the analogue outputs A to D
(measured variable, full-scale value, limits and settling
time for each output)
Fig. 10. Programmation of the output quantities.
• 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 up-
loaded via the MODBUS interface (RS 485) together with
the device address and the data transfer parameters
Fig. 11. Definition of the measured variables on the bus.
• Measurements displayed: Analogue output signals
(RS 232) and all measured variables selected on the
transducer that has been addressed
