2.3 Function blocks and the PROFIBUS PA Profile
The Analog Input Function Block agrees with PROFIBUS PA Profile 3.02. The Analog Input
Function Block is the data interface to a process control system (a PLC, ...). The control system
(cyclic communication services) can read data.
The device has these blocks:
The level transmitter is a modular device with 4 slots. Each Analog Input Function Block uses
one slot (as a virtual module). The user cannot change this setting. But the user can change the
measurement name and unit for each Function Block. Refer to the table that follows:
If you change device-specific parameters, we recommend that you set device and system length
units to millmetres (mm). New settings are rejected if system length units and device length
units are different.
INFORMATION!
The PROFIBUS PA Profile 3.02 has a standard set of parameters and functions available for
PROFIBUS devices used in process control. The PROFIBUS device is a function block application
in which parameters and functions are grouped into different blocks.
Block Usage
1 Physical Block (PB) contains identification and diagnosis parameters of the device
1 Transducer Block contains parameters and functions to control the level measurement
4 Analog Input Function Blocks
(AI-FB) contains parameters and functions to control the measuring output; provides the measuring value(s)
INFORMATION!
If it is necessary to change the measurement name, change the channel parameter in the acyclic
PROFIBUS services.

3.1 Topology of a PROFIBUS PA network
The following diagram shows a typical network configuration with PROFIBUS PA devices in
hazardous and non-hazardous areas, as well as the connection of conventional non-PROFIBUS
devices (e.g. with 4 …20 mA signals) to a PROFIBUS network.
The PROFIBUS PA segment is connected to a segment coupler which, among other things,
provides the conversion to the PROFIBUS DP bus line. In addition it provides the power supply for
bus–powered PROFIBUS PA devices. Refer to the instruction manual of the segment coupler
concerning the DP bus parameters, e.g. the supported baud rates.
Refer also to the PROFIBUS PA User and Installation Guideline (Version 2.2, February 2003 PNO
Order No. 2.092).

3.2 Electrical connection for signal converter
Bus cable - Shielding and grounding
The statements of the FISCO model only apply if the used bus cable meets the required
specifications.
In order to ensure optimum electromagnetic compatibility of systems it is important that the
system components, and in particular the bus cables, are shielded. Gaps in the shields must be
as small as possible.
Use the shortest possible length of shield wire to connect the electrical cable to the grounding
terminal.
INFORMATION!
The PROFIBUS PA interface of the signal converter will operate only if the power supply is
connected/available. The device terminal is not sensitive to electrical polarity.

We recommend that you connect the two ends of the shield wire insulation (between the device
and the control system) to ground (PE), as given in the fieldbus specifications. If the ground (zero
potential) for the device and the control system are different, connect the supplied capacitor to
the grounding terminal on the device housing. For more data, refer to the procedure that
follows.
Equipment needed
•Device
•Handbook
•Capacitor (supplied in a transparent plastic bag with the device)
•T10 Torx wrench (not supplied)
•Small slotted-tip screwdriver (not supplied)
• Remove the terminal compartment cover.
• Remove the capacitor from the transparent plastic bag.
• Connect the capacitor to the grounding terminal 1. Tighten the terminal screw with a T10
Torx wrench.
• Use a small slotted-tip screwdriver to connect one end of the shield wire insulation to the
capacitor.

4.1 Hardware settings
There is a DIP switch block with 8 switches on the level transmitter module to set the PROFIBUS
device address and prevent changes to the station address from the network.
Figure 4-1: How to use the DIP switches to change the station address
1 Hardware DIP switch
OFF: The user can set the station address with the network bus
ON: The user can set the address of the device with the 7 other DIP swtiches (item 2). You cannot use the network bus
or the local display to change the station address.
2 7 "Station Address" DIP switches. Each DIP switch is a bit position (bits 0...6). Bit 0 is on the left side of the switch
block.The base 10 value of each bit is given in the table that follows. This data is used to calculate the "Station Address"
number.
OFF: binary number "0".
ON: binary number "1".
INFORMATION!
If the Hardware DIP switch is set to "ON", the hardware is locked and you cannot use the network
bus to change the station address.
