Integration

Connecting to SIMATIC PCS 7

The integration of field devices in SIMATIC PCS 7 and other

process control systems can now be done seamlessly and cost-

effectively with wireless technology, especially in situations

where high wiring costs may be expected. Of particular interest

are measuring points which are to be added and for which no

MSR wiring is available.

Where larger distances between the IW/WSN-PA LINK and

control systems need to be overcome, this connection can also

be implemented on a wireless and cost-effective basis using the

products of the SCALANCE W family.

The Siemens WirelessHART devices are designed for optimum

compatibility with products of the SCALANCE W family.

Configuration

Configuration of the SITRANS TF280 transmitter may be carried

out as follows:

• Initial start-up for the SITRANS TF280 with SIMATIC PDM is

generally carried out via a HART modem or the integrated

local user interface, since the network ID and join key must be

set up on the device before it can be accepted and integrated

into the WirelessHART network.

• Once it is integrated into the network, the device can be

conveniently operated with the WirelessHART network, the

onsite HART modem or via the local user interface.

■

Technical specifications

The SITRANS TF280 can be mechanically installed in two ways:

• direct at the measuring point with a M20x1.5 thread

Connection to other threads can be done via the adapter.

• offset from Pt100 sensor, which is connected to the transmitter

via a cable

The details in the table below relate to the transmitter without

taking into account a connected sensor, unless otherwise

specified.
