• Work on the device should only be carried out by specialist staff using
suitable tools!
• Observe the valid accident prevention and safety regulations for electrical
equipment during the operation, maintenance and repair of the equipment!
• Always switch off the voltage supply before working on the system!
• Only use lines fitted with an earth line, and connect the earth!
• Take suitable measures to prevent unintentional operation or impermissible
impairment.
• If these instructions are ignored, or if inadmissible work is carried out on the
device, no liability will be accepted from our side, and the guarantee on the
device and accessory parts will become invalid!
ATTENTION!
CAUTION ON HANDLING!
COMPONENTS / MODULES
LIABLE TO ELECTROSTATIC
DAMAGE!
The device contains electronic components that
are sensitive to electrostatic charging (ESD).
These components are endangered by contact
with statically charged persons or objects. In the
worst case they are immediately destroyed or
fail after putting into operation. Observe the
requirements of EN 100 015 - 1 in order to
minimize or avoid the risk of damage by
instantaneous electrostatic discharge. Make
sure also that you do not touch electronic
components when they are under supply
voltage.

• Driven by a PROFIBUS PA
• De-central unit for efficient collaboration with a central automation equipment
(e.g., process control system)
• High process security due to bi-directional transmission of signals
- switching commands from process control system to valve
- sensor signals for registration of the valve position of the process valve.
• The device may be operated with the extended PROFIBUS DP-
Communication (DPV1) in the cyclic and acyclic modes. The process values
are controlled via the cyclic data traffic, e.g. from a PLC. Configuration is
carried out from an operating device via the acyclic data traffic (e.g.
CommuWins SIMATIC PDM).
With regard to the parameters for the configuration and the process data
traffic, the “PROFIBUS PA
Profile for Process Control Devices ” applies. The
obligatory and optional parameters which are available in the unit are defined
in this document. The profile documentation can be obtained from the PNO
(PROFIBUS Utilisation Organisation).
3.1 I/O Box Type 8642 with PROFIBUS PA Circuit
3.2 PROFIBUS PA
The PROFIBUS PA connects the automation system and the process control
system with the de-central field units. It uses the extended PROFIBUS DP
protocol in connection with the transmission technology according to IEC 1158-2.
PROFIBUS PA fulfils the special requirements of traffic technology, e.g., for the
chemical and petrochemical areas:
• Uniform application profile for process automation and complete inter-
operability between various PROFIBUS PA devices.
• Connection of the process automation with the PROFIBUS PA to the
general automation via the PROFIBUS DP using the transmission
technology to EIA RS 485 or optical waveguides
• Remote supply and data transmission in two-wire technique with PROFI-
BUS PA
• Use of PROFIBUS PA within areas with danger of explosion with explosive
protection class Inherent Safety through application of transmission
technology to IEC 1158-2
• Simple linking of the PROFIBUS DP and PROFIBUS PA bus segments by
means of segment couplers

10 - 8642
english
In the same way as for operation outside areas with danger of explosion, work
can also be carried out within the Ex-area with PROFIBUS PA with “e”
protection Inherent Safety.
The planning of the non-inherently safe and inherently safe systems takes place
following the same open concept. Field units can be switched together with
various topologies, and be completely supplied via the bus. The units can also
be operated and be connected or disconnected during operation within the
explosion-risk area [1].

In the PROFIBUS PA, each station is given an address. These addresses are
set up using the DIP switches 1 to 7.
The permissible address range lies between 3 and 124
Settings:
NOTE If switch 8 is in the ON position, the internal address is used!
This address can be set up via the field bus.
permitted address range 3 ... 124
5.2.3 LED Display
The LED flashes when the device is engaged in cyclic data communication.
The LED lights briefly on connecting the device.
If the device detects an internal error, the LED remains lit.
5.2.4 Watchdog
In order to recognize errors better, we recommend operating the device in
cyclic data communication with „DP watchdog“.

6 CONFIGURATION OF THE NETWORK
6.1 Memory allocation for the effective data traffic
Basis: handbook for your PLC
In order to be able to carry out the correct settings of the configuration
program, copy the unit-specific file (buer6521.GSD) from Bürkert into the
directory that contains the configuration software. For reading in and editing
the configuration, please read the documentation for your PLC or process
control system.
Further information regarding memory allocation can be found in the handbook.
6.2 System parameters
NOTE All profile data refers to the profile Version 3.0 Class B.
There, you will also find detailed information about the
parameters.
ATTENTION!
When writing in parameters, ensure that the voltage is
present!
6.2.1 Physical block
6.2.1.1 Slot 0
Parameter type:
N non-volatile parameter which must be taken into
account in the work cycle. It does not belong to the
static update code however.
S Static, non-volatile; when writing, the version counter
ST_REV is incremented
D (dynamic) The value will be calculated in the block, or be read
from another block
C (constant) The parameter does not change.

MODE _BLK This parameter contains the current mode and the
permitted and normal mode of the block
ST_REV A block has static block parameters, that are not
changed by the process. Values are assigned to this
parameter during the configuration or optimisation. The
value of theparameter ST_REV must increase by 1
after every change of a static block parameter. This
provides a check of the parameter revision.
STRATEGY Grouping of Funtion Block. The STRATEGY field can be
used to group blocks.
TAG_DESC Every block can be assigned a textual TAG description.
The TAG_DESC is the address of the block. The
TAG_DESC must be unambiguous and unique in the
fieldbus system.
TARGET_MODE The TARGET_MODE parameter contains desired mode
normally set by a control application or an operator.
ALARM_SUM This parameter contains the current status of the Block
Alarms. The parameter ALARM_SUM is not supported
at the moment.
ALERT_KEY This parameter contains the identification number of the
plant unit . It helps to identify the location (plant unit) of
an event (crossing a limit).
6.2.1.2 Description of the standard parameters
These parameters are contained in the physical block, the functional block and
the transducer block.
