Second generation Cerabar S PROFIBUS-PA devices with 3.0 profiles are cyclical
downwards compatible with the first generation Cerabar S PROFIBUS-PA devices
with 2.0 profiles, i.e. first generation devices can be replaced with second generation
devices.
However, to use the additional functions of second generation devices with
3.0 profiles, such as cyclical reading of two additional values, the PLC must be
configured with the GSD (EH3x1501.gsd or EH3_1501.gsd).
If the additional functions of the 3.0 profile are not required, the PLC configuration with
the first generation GSD (EH__1501.gsd) can be kept.

1 Introduction
ApplicationsThe Cerabar S pressure transmitter measures the pressure of gases, steam/vapour and
liquids and can be used in all areas of chemical and process engineering.
Operating principle
Ceramic sensor
The system pressure acts directly on the
rugged ceramic diaphragm of the pressure
sensor deflecting it by a maximum of
0.025 mm. A pressure-proportional change
in the capacitance is measured by the
electrodes on the ceramic substrate and
diaphragm. The measuring range is
determined by the thickness of the ceramic
diaphragm.
Metal sensor
The process pressure deflects the
separating diaphragm with a filling liquid
transmitting the pressure to a resistance
bridge. The bridge output voltage, which is
proportional to pressure, is then measured
and processed.
Level measurement
The hydrostatic pressure of a column of
liquid enables its level to be measured
continuously by a pressure transmitter if the
density ρof the liquid is known.

1.1 Measuring system
Measuring point In the simplest case, the measuring point comprises:
•Cerabar S with PROFIBUS-PA protocol
•PLC or personal computer with an operating program e.g. Commuwin II
•Segment coupler
•PROFIBUS-PA terminating resistor
Number of transmitters The maximum number of transmitter on one bus segment is determined by their
consumption, the power of the bus coupler and the required bus length, see Operating
Instructions BA 198F/00/en. Normally however:
•max. 10 Cerabar S for hazardous area applications
•max. 32 Cerabar S for non-hazardous area applications
can be operated on one bus segment. Cerabar S consumes max. 11 mA per device.
For further information, see Operating Instructions BA 198F "PROFIBUS-DP/-PA:
Guidelines for planning and commissioning", the PNO Guidelines or under the Internet
address http://www.PROFIBUS.com and for operation in hazardous ia areas: EN 50020

•the electrical connection
2.1 Mounting instructions without diaphragm seal (PMC/PMP 731)
Cerabar S
without diaphragm seal
– PMC 731
– PMP 731
The Cerabar S without diaphragm seal is mounted in the same way as a manometer
(DIN EN 839-2). The use of shut-off valves and pigtails is recommended. Its position
depends upon the application.
•Measurement in gases:
Mount the shut-off valve above the
tapping point so that condensate can
run back into the process.
•Measurement in steam:
Mount with a pigtail below the tapping
point.
The pigtail reduces the temperature in
front of the diaphragm to almost
ambient temperature. The pigtail must
be filled with fill fluid before start-up.

•Measurement in liquids:
Mount on the shut-off valve below the
tapping point or at the same height.
PVDF adapter For instruments with PVDF adapter, a maximum torque of 7 Nm is permitted. The thread
connection may become loose at high temperatures and pressures. This means that the
integrity of the thread must be checked regularly and may need to be tightened using
the torque given above. Teflon tape is recommended for sealing with the ½ NPT thread.
Mounting the PMP 731 The PMP 731 with metallic sensor is available in the following versions:
•with flush-mounted diaphragm or
•with adapter (screwed on or welded in) and internal diaphragm.
A seal is enclosed appropriate to the material used and version.
Note!
The diaphragm of the Cerabar S must not be pressed in or cleaned with pointed or hard
objects.

2.2 Mounting instructions with diaphragm seal (PMC 631, PMP 635)
Cerabar S
with diaphragm seal
– PMC 635
– PMP 635
The Cerabar S with diaphragm seal is
screwed in, flanged or clamped,
depending on the type of diaphragm seal.
•The protective cap of the diaphragm
seal should only be removed just before
mounting in order to protect the
diaphragm.
•The membrane of the diaphragm seal of
the Cerabar S must not be pressed in or
cleaned with pointed or hard objects.
•The diaphragm seal and the pressure
sensor together form a closed and
calibrated system which is filled with
filling fluid through a hole in the upper
part. The following rules should be
observed:
–This hole is sealed and not to be
opened.
–The device may only be rotated on
the surface provided on the
diaphragm seal instrument and not on
the housing.
Level measurementFor level measurement the Cerabar S must
always be installed below the lowest
measuring point.
•The instrument should not be installed
within the flow of material, in the outlet
of the tank or at a place in the tank
where pressure pulses from agitator
blades may occur.
•Calibration and function testing are
easier to carry out if the Cerabar S is
mounted downstream from a shut-off
valve.
Mounting with
temperature spacers
The use of temperature spacers is
recommended for continuous extreme
product temperatures.
•Note when mounting that the
temperature spacer increases the
maximum height by 100 mm.
•Due to the hydrostatic column in the
temperature spacer, the increased
height also causes a zero point shift of
approx. 10 mbar.
See Chapter 5.1, page 32 and Chapter
5.2, pages 34…35 for information
concerning position calibration (display
only) or zero-point correction.

3.2 Setting the device address
Every PROFIBUS-PA device must be given an address. If the address is not set correctly,
the device will not be recognised by the process control system.
•Addresses between 0 and 126 are valid, whereby all Endress+Hauser devices are
supplied ex-works with the software address 126.
•A device address may appear only once within a particular PROFIBUS-PA network,
see Operating Instructions BA 198F.
The default address can be used to check the function of the device and connect it to
an operating PROFIBUS-PA system. Afterwards the address must be changed to allow
other devices to be connected to the network.
There are two possibilities to set the address of the Cerabar S:
•remotely by using an operating program, e.g. Commuwin II, running as a
PROFIBUS-DP Class 2 master
•locally at the device DIP-switches that are to be found behind the operating and
display module in the display compartment.
Addressing modeSet the addressing mode at Switch 8:
•ON = software addressing via the bus system (default setting) (SW)
•OFF = hardware addressing at the device via DIP switches 1 to 7 (HW).
Hardware addressProceed as follows to set a hardware address:
1. Set Switch 8 to OFF = hardware addressing.
2. Set a unique hardware address at Switches 1 to 7 according to the table below.
3. The address becomes effective 10 s after the switches have been changed.
Software addressThe procedure for changing a software address is described in BA 198F.

3.3 Device database and type files
A device database file contains a description of the properties of the PROFIBUS-PA
device, e.g. the supported transmission rates and the type and format of the digital
information output to the PLC. The bitmap files also belong to the .gsd files. These allow
the measuring point to be represented by an icon. The device database file and
corresponding bitmaps are required by the network design tool of the PROFIBUS-DP
network.
Every device is allocated an identity code by the PROFIBUS User Organisation (PNO).
This appears in the device data base file name (.gsd). For Endress+Hauser devices, the
identity code is always 15xx, where xx is device dependent.
The full set of device data base files for Endress+Hauser devices can be obtained as
follows:
•INTERNET:
Endress+Hauser →
http://www.endress.com
then →Products →Product Portfolio
→Process Solutions →PROFIBUS →GSD files
PNO →
http://www.PROFIBUS.com (GSD library)
•As CD-ROM direct from Endress+Hauser: Order No. 56003894
Note!
The PNO also provides a universal database file with the designation PA_x9700.gsd for
devices with one analog output block. Should this be used instead of the Cerabar S file,
then only the process value can be transmitted. The transmission of a second measured
value (2nd Cyclic Value) or a display value are not supported. The universal profile must
also be selected in field V6H0 in Commuwin II.
Working with GSD files The GSD files must be loaded into a specific subdirectory in the PROFIBUS-DP network
design software of your PLC.
•GSD files and bitmaps that are located in the directory "Typdat5x", for example,
are required for the planning software STEP7 used by the Siemens S7-300/400
PLC family.
•x.200 files and bitmaps that are located in the directory "Extended" are required
for the planning software COM ET200 for the Siemens S5.
•The GSD files located in the directory "standard" are for PLCs that support the
"identifier byte" (0x94) but not the "identifier format". These are for use e.g. with
the Allen-Bradley PLC5.
More details about the directories used for storing the GSD files can be found in
Chapter 6.4 of BA 198F which describes the network design.

3.4 Cyclic data exchange
Block modelFig. 3.3 shows a block model of the Cerabar S. The primary value V0H0 is output by the
transducer block and used as the process value for the analog input block. Here it is
scaled, processed and rescaled before being output as cyclic data to the PLC as the
variable OUT. This comprises a value and status.
The on-site display and the matrix field V0H0 normally show the same value. The on-site
display can also be set to show a cyclical output value (Display Value) using a PLC. For
this the matrix field V6H5 in Commuwin II is set to "Display Value" (or 1). Example: Two
Cerabar S transmitters measure the pressure drop across a filter. The differential
pressure is registered in the PLC and then allocated to the matrix field V6H6.
A Cerabar S can still supply two other values to the PLC. The field V6H4 in Commuwin II
allows one of four values to be selected (see following Section, Step 7).
ConfigurationThe data exchange is configured in the network design tool and Commuwin II.
1) Using the network design tool for your PLC, add the Cerabar S to the network,
taking care that the address assigned corresponds to that set at the device.
2) Select the Cerabar S and call up the configuration tool: five options appear:
– "Main Process Value", "2nd Cyclic Value", "3rd Cyclic Value", "Display Value",
"FREE PLACE"
3) Select "Main Process Value". If no additional value is required apart from the "Main
Process Value", close the configuration window.
4) Select "2nd Cyclic Value" or "FREE PLACE" (= function deactivated),
select "3rd Cyclic Value" or "FREE PLACE" (= function deactivated) and
select "Display Value" or "FREE PLACE" (= function deactivated).
Then close the configuration window.
5) Start Commuwin II and open the connection using the PA-DPV1 server.
Generate a live list, locate the device address and click on "Cerabar S".
6) Open the device menu and select the parameter matrix.
7) If a secondary value is to be output, select the type in V6H4:
0 = Temperature, 1 = Sensor value, 2 = Trimmed value, 3 = Biased value .
8) To display a cyclic output value on the on-site display, set V6H5 = "Diplay Value"
(or 1)
9) The data exchange is now configured for the Cerabar S in question.
