Profinet data in OPC UA
Picture: Profibus Nutzerorganisation
In close cooperation, and within
the framework of a joint working
group, experts from Profibus
& Profinet International (PI)
and the OPC Foundation have
specified a solution for presenting
Profinet data in the OPC UA
object model. Profinet’s OPC UA
companion specification is set
to be reviewed soon.
According to extensive coordination
talks with users, the most
significant content of Profinet’s
OPC UA companion specification
includes the collection
and display of asset management
and diagnostic data. This
information can be displayed
flexibly in specific ways on various
devices, based on the
requirements and possibilities.
Asset and diagnostic data from
the devices employed today can
be collected in a system controller
through existing mandatory
Profinet services and delivered
to higher-level entities
by means of OPC UA. This service
can also be offered by an
edge gateway, which can additionally
be added to the system.
The advantage here is that no
changes have to be carried out
on the controller. These use
cases are predestined for innovating
characteristic brownfield
systems. It is also possible to directly
integrate the OPC mapping
in a Profinet field device.

Mass flow meters and controllers for gases
Mass-Stream instruments operate
on the basis of direct
through-flow measurement in
accordance with the constant
temperature anemometer principle.
They contain no moving
parts and the measured gases
pass the two stainless steel sensor
probes directly, without bypass.
As a result, the gases are
entirely unhindered on their
flow path, making the series
particularly suitable for applications
with low pressure loss as
well as less sensitive to moisture

than thermal mass flow instruments
with a bypass sensor. The
electronics casing has a robust
design with an IP 65 level of
protection (dustproof and
splash waterproof). The mass
flow meters and controllers can
be supplied with an optional integrated
multifunctional display.
On the new developed D-6390
model, the maximum measuring
range has been expanded to
10 000 l n /min air equivalent.
Analogue I/O signals as well as
an RS232 interface are provided
by default. In addition, an interface
with DeviceNet, Profibus
DP, Modbus or Flow-Bus protocols
can be integrated.
