Intended Use
In their directive “Title 21 Code of Federal Regulations, 21 CFR Part 11,
Electronic Records; Electronic Signatures“ the US American health agency
FDA (Food and Drug Administration) regulates the production and processing
of electronic documents for pharmaceutical development and production.
This results in requirements for measuring devices used for correspond-
ing applications. The following features ensure that the M 700(X) modular
process analysis system meets the demands of FDA 21 CFR Part 11:
Electronic Signature
Access to the device functions is regulated and limited by individually adjust-
able codes – “Passcodes“. This prevents unauthorized modification of device
settings or manipulation of the measurement results. Appropriate use of
these passcodes makes them suitable as electronic signature.
Audit Trail Log
Every change of device settings can be automatically recorded and docu-
mented in the Audit Trail Log on the SmartMedia card. The recording can be
encrypted.
Conformity with FDA 21 CFR Part 11
The module is a communication unit for PROFIBUS-PA and allows digital
communication via current modulation.
The PA 700X module is intended for operation in locations subject to explo-
sion hazards which require equipment of Group II, device category 2(1), gas/
dust.

Safety Information
Application in Hazardous Locations
Caution!
Never try to open the module! If a repair should be required, return the
module to our factory.
If the specifications in the instruction manual are not sufficient for assessing
the safety of operation, please contact the manufacturer to make sure that
your intended application is possible and safe.
Application in Hazardous Locations:
PA 700X Module
When using the PA 700 X module, the stipulations for electrical installations
in hazardous areas (EN 60079-14) must be observed. When installing the
device outside the range of applicability of the 94/9/EC directive, the appro-
priate standards and regulations in the country of use must be observed.
The module has been developed and manufactured in compliance with the
applicable European guidelines and standards.
Compliance with the European Harmonized Standards for use in hazardous
locations is confirmed by the EC-Type-Examination Certificate.
Compliance with the European guidelines and standards is confirmed by the
EC Declaration of Conformity.
There is no particular direct hazard caused by the operation of the device in
the specified environment.
Be sure to observe during installation:
Switch off power supply before replacing or inserting a module.
Before commissioning it must be proved that the device may be connected
with other equipment.

PROFIBUS Technology
PROFIBUS is a digital communication system that connects different field
devices over a common cable and integrates them into a control system. In
the long term, PROFIBUS will replace the 4-20mA technology, which only
supplies pure measured values. Advantages of the PROFIBUS technology are:
easy and cost-saving cabling
convenient operation over a central control station
transmission, evaluation, and control of high amounts of data from field
device to control station.
devices installed in hazardous locations are configured and maintained
from the control station
PROFIBUS is the leading open fieldbus system in Europe. Its application range
covers manufacturing, process, and building automation. As open fieldbus
standard to EN 50170 and IEC 61158, PROFIBUS ensures communication of
different devices over one bus. The PROFIBUS User Organization (PNO) pro-
vides for further development and maintenance of the PROFIBUS technology.
It combines the interests of users and manufacturers.
Variants and Basic Characteristics
PROFIBUS determines the technical and functional characteristics of a serial
bus system. There are three PROFIBUS variants:
PROFIBUS-DP (decentralized peripherals)
Tailored for communication of automation systems and distributed periph-
erals.
RS 485 standard with transmission rates up to 12 MBits/sec
PROFIBUS-PA (process automation)
Dedicated to the process industry. It permits connection of sensors and
actuators to a common bus even in hazardous locations. PROFIBUS-PA has
a transmission rate of 31.25 kBits/sec.
15
PROFIBUS Technology
PROFIBUS distinguishes between two types of devices:
Masters
Control the data traffic on the bus. They send messages without external
request.
Slaves
Peripheral devices such as valves, drives, transmitters, and analyzers. They
can react acyclically to servicing, configuration and diagnostic tasks of the
master. The central controller cyclically reads the measurement data with
status.
Definitions for PROFIBUS-PA
The bus protocol defines type and speed of the data exchange between
master and slave devices and determines the transmission protocol of the
respective PROFIBUS system.
PROFIBUS-PA permits cyclic and acyclic services.
Cyclic services are used for transmission of measurement data and actuating
commands with status information.
Acyclic services are used for device configuration, maintenance and diag-
nostics during operation.
The PA 3.0 device profile defines the device class and typical functionalities
with parameters, ranges, and limit values.
The FISCO model developed by the German PTB for hazardous locations per-
mits connection of several devices to one common bus and defines permis-
sible limits for device and cable parameters.

PA 700(X) Module
Attaching the Terminal Plates
The terminal plates of the lower modules
can be sticked to the inner side of the door.
This facilitates maintenance and service.

Inserting the Module
Switch off power supply
Open the device (loosen the 4 screws at the front)
Place module in slot (D-SUB connector)
Tighten fastening screws of the module
Connect signal lines
Close device, tighten screws at the front
Switch on power supply
Assigning process variables to AI blocks on the device
Set parameters
Make sure that the cable
glands are tightly closed to
protect against humidity.
Thanks to the staggered arrangement of
connectors and fastening screws the termi-
nal strips of all modules are easy to access.

The device parameters are sorted in three types of blocks:
Physical Block (PB)
This block contains the general parameters which apply to the whole device.
Transducer Blocks (TB 1 ... TB 8)
8 analog blocks. They contain measurement parameters (process variable,
temperature) according to the PROFIBUS-PA Profile 3.0 specification.
Function Blocks
8 analog input blocks (AI1..4, AI5..8, for scaling measured values),
4 digital output blocks (DO 1 ... DO 4, for control signals)
4 digital input blocks (DI 1 ... DI 4, for status messages).
1 analog output block (AO 1) for analog compensation signals,
e.g. O
2
process pressure.
Physical Block (PB)
This block contains the device-specific parameters (model designation, manu-
facturer ID, serial number...) and controls basic device functions such as:
Write protection
(“WRITE_LOCKING” parameter) Enables or locks acyclic services
(maintenance, configuration).
Blocking operator access to the device
(“LOCAL_OP_ENA” parameter)
Enables or locks access via the user interface on the device.
Notice:
When communication fails for more than 30 seconds,
the device automatically switches to local access.
Reset
(“FACTORY_RESET” parameter)
Caution – data loss!
Resets all configuration values to factory setting.
