2.2 Device description
This device is a 2-wire level transmitter that uses TDR (Time Domain Reflectometry) / Guided
Radar technology. It measures the distance of liquids, liquid gases, pastes, powders, slurries
and granular products.
The level transmitter has an MBP (Manchester-coded, bus-powered) interface to connect the
device to a PROFIBUS PA network, when equipped with the appropriate options.
The level transmitter is approved for use in potentially explosive atmospheres when equipped
with the appropriate options.

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 or write input and output data.
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.
The device has these blocks:
Block Usage
1 Physical Block (PB) contains identification and diagnosis parameters of the device
1 Level Transducer Block (TB-Level) contains parameters and functions to control the level
4 Analog Input Function Blocks (AI-FB) contains parameters and functions to control the measuring
measurement
output; provides the measuring value(s)

OPTIFLEX 2200 C
The device has 4 slots. The Analog Input Function Blocks use slot 1 (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:
INFORMATION!
If it is necessary to change the measurement name, change the channel parameter in the acyclic
PROFIBUS services.

3 ELECTRICAL CONNECTION
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.

ELECTRICAL CONNECTION 3
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. These shields must have as
few gaps as possible.
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.
Figure 3-2: Electrical installation: terminals
1 Power supply / communication terminal
2 Power supply / communication terminal
3 Grounding terminal
Use the shortest possible length of shield wire to connect the electrical cable to the functional
earth (FE) terminal.

4 COMMISSIONING / OPERATION
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.
OPTIFLEX 2200 C
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.
