2 Product description
2.1 Function
It is possible to connect to a Profibus-DP system via the connector (M12, B-coded) designated "Profi-
bus". The interface is galvanically safe and is isolated from the maximum supply voltage. The gauge's
voltage supply is provided via the RS-485 connector.

3 Installation
3.1 Establish Profibus connection
NOTICE
Property damage on the electronics
Separating all plug-and-socket connections within the bus system with voltage supply switched on
may lead to the destruction of electronic components.
►Always disconnect the voltage supply before removing the connecting plug.
►After switching off the power supply pack, wait until the residual load has dispersed completely
before disconnecting the plug-and-socket connection.

Procedure
1. Select a valid and unique Profibus address at the address selector switches in decimal coding
from 1 to 125.
–If you set the Profibus address while the voltage supply is switched on, the gauge only applies
the address change after a restart (supply voltage off/on).
2. Fit the rubber plugs over the address selector switches straight and as deep as possible to ach-
ieve the stated protection degree.
3. Establish the Profibus connection in compliance with the applicable guidelines.
4. Connect the voltage supply to the gauge via the RS-485 connector in compliance with the regula-
tions in force.
5. Use a suitable connection cable and components from the Pfeiffer Vacuum line of accessories.

3.2 Configure Profibus connection for CCT gauges
Profibus configuration tools
There are various suppliers of configuration tools for configuring the Profibus. The configu-
ration procedure is identical. The figures show the Siemens TIA portal by way of an exam-
ple.

Procedure
1. Download the gauge's GSD file from the Pfeiffer Vacuum Download Center.
2. Open the configuration tool.
3. Import the unzipped files (GSD file and image) into the process control.
–You will find the CCT gauge under the path PROFIBUS DP/Gateways/Pfeiffer Vacuum/CCT
3xx PB.
4. Drag and drop CCT 3xx PB into the configuration tool's network area and integrate CCT 3xx PB
there.
5. Select the input and output modules for the gauges you are using.
6. Drag all catalog objects from "Actual Pressure" to "Set Correction Factor BA" into the active area.
7. Compile the entries.
8. Check the correct function of the entries online.

3.3 Configure Profibus connection for xPT gauges
Profibus configuration tools
There are various suppliers of configuration tools for configuring the Profibus. The configu-
ration procedure is identical. The figures show the Siemens TIA portal by way of an exam-
ple.
Configure switching ranges for xPT gauges
You can configure the switching ranges in the Profibus parameter data for the HPT 200 PB,
MPT 200 PB and RPT 200 PB gauges. You can find information in the operating instruc-
tions of the standard version of the gauge.
If the default setting specified in the operating instructions is OK for your application, you
do not need to edit the configuration. Select xPT 200 PB_2_1 and assign the device-specif-
ic parameters to the desired switching range.

Compute effective correction factor
The admissible value range of the entered correction factors is between 1 and 800. It is equivalent to
effective correction factors between 0.01 and 8.00.
►Multiply the entered correction factor by 0.01 to calculate the effective correction factor.

5 Operation
5.1 Operate gauge via Profibus interface
NOTICE
Data transmission error due to simultaneous operation on both interfaces
If you attempt to operate the gauge simultaneously via the RS-485 and Profibus interfaces, this will
result in incorrect data and interference with the data transmission.
►Operate the gauge via only one of the two interfaces.
►Only use the RS-485 connector in Profibus operation to supply voltage to the gauge.
