PROFIBUS-PA Electronics
A Cerabar M with PROFIBUS-PA
electronics has the following operating
options.
•
You can set a damping of between 0
and 40 s using communication.
•
You can set instrument bus address
direct in the instrument using the
address switch.
•
The digital display gives the pressure
as a four-digit number. The bar graph
depicts the current pressure value
related to the measuring range. The
measuring range can be set either on
site using the Zero and Span keys or
remotely using an operating program,
such as Commuwin II.
•
Error codes on the digital display and
in Commuwin II simplify error
diagnosis.
Smart Electronics Operation Using a
Handheld Terminal
Using the Universal HART
Communicator DXR 275 handheld
terminal, you can set the Cerabar M,
make checks and use additional
functions such as "Damping" and
"Calibration without reference pressure"
all along the 4...20 mA line.
