Functional Description

A Linking Device consists of one head station and at least one power link module for establishing the

connecton of PROFIBUS PA Segments to PROFIBUS DP. PROFIBUS is standardized accorting to EN 50

170/2. The head station supports all there defined transfer rates from 45.45 kBit/s up to 12 MBit/s.

The head station provides one channel. Up to 5 power link modules can be connected to one channel.

Each power link module creates a new segment.

The communication between the head station and the Power Link Modules is realized via removable

terminal blocks.

The communication is transparent. Each PA-subscriber is planned like a PROFIBUS DP subscriber and each

PA device is directly addressed like a DP slave device. The head station and the power link modules don’t

need to be planned.

It is allowed to mount the head station, and the power link modules within zone 2.

The channels are working with 31.25 kBaud (Manchaster coded). This saves from additonal time delay

within the Power Link Modules.

(3BDD011704R0101).

The RAO02 module has one D/A converter for each output channel.

In current mode, the RAO02 module supports HART v5.4 instruments and

provides short circuit protection by limiting current to a maximum of 26 mA.

The RAO02 module will also detect an open circuit in less than 5 seconds.

The RAO02 Redundant Analog Output module processes up to 16 high-level,

group isolated, analog output field signals.

Each channel is independently configurable for either 4 to 20 mA or 1 to +5 VDC ranges.

FC 221 (I/O Device Definition) sets AO module operating parameters and

each output channel is configured using FC 223 (Analog Output CH) to

set indivdual output channel parameters such as engineering units,

High/Low Alarm limits, default value in event of loss of communication with controller, etc.

D/A resolution of each channel is 12 bits.

The RAO02 module has one D/A converter for each output channel.

In current mode, the RAO02 module supports HART v5.4 instruments and

provides short circuit protection by limiting current to a maximum of 26 mA.

The RAO02 module will also detect an open circuit in less than 5 seconds.
