1.3.4.3 Configuration
The communication in the Profibus occurs cyclically (permanent data
exchange such as e.g. the humidity and temperature readings) as well as
acyclically (data exchange dependent on event such as e.g. status, warning
and error messages).
The testo 6681 has two measurement channels that are provided for the
Profibus interface.
Parameters can be found in chapter 1.2.7, page 16.
- 1.3 Commissioning
In the condition on delivery, measurement channel 1 is set
with temperature (°C) and measurement channel 2 with
relative humidity (% RH) for Profibus.
To Change the factory settings for the testo 6681 via
Profibus, the Profibus parameterization tool Siemens Simatic
PDM is required, for example (see chapter 1.3.5, page 49).
For the cyclical service, you must ensure that the GSD file
(General Station Description) was read into the master
class 1 in the configuration tool.
The GSD can be obtained under:
www.profibus.com/pb/applications/gsd,
www.testo.com or can
be downloaded from the product CD that is included with
the testo 6681.
