266CRH / 266CRT, 266CSH / 266CST MULTIVARIABLE PRESSURE TRANSMITTER | OI/266CXX/MODBUS-EN REV. A
... 7 Commissioning
Configuration with the PC / laptop
The 266Cxx multivariable transmitters can be configured with
the aid of the following devices:
•
ABB Asset Vision Basic, a free-of-charge software
configurator, that can be downloaded at
www.abb.com/measurement.
•
Software for configuration of field devices, with the
prerequisite that it is compatible with DTM.
With the graphic user interface (DTM) all configuration
possibilities are available. The procedure for program
installation is described in the appropriate installation manual
delivered with the software.
The transmitter can be configured, read out and tested via the
program. With the aid of the integrated database a
configuration can also be executed in offline mode. Each
configuration step is subject to a plausibility check. For each
point of the program a context sensitive help can be called via
'F1'.
Immediately after receipt of the transmitter or after changing
the configuration, we recommend that back up the existing
configuration on a separate data medium under 'Save in
database'.
Operating instructions for the program 'Asset Vision Basic' are
provided in the appropriate user manual.
A RS485 interface will be needed for communication between PC
and transmitter.
•
The driver for this interface must support a COM port.
•
The communication DTM (for example 'ABB HART
Communication Servicepoint') must be set to the same
COM port as the RS485 interface.
•
The baud rate for configuration of the transmitter is fixed to
9600 baud and must be set to the same value inside the
communication DTM.
•
The communication protocol of the transmitter has to be set
to 'CONFIG/HART-RS485' with dip switch, HMI menu or
Modbus Master.
For operating with a Modbus master after configuration must
the transmitter be set back to 'OPERATE/MODBUS' with the
DTM, HMI or dip switches.
