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 corresponding applica-
tions. The following features ensure that the Protos 3400(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
documented in the Audit Trail Log on the SmartMedia card.
The recording can be encrypted.

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 dif-
ferent devices over one bus. The PROFIBUS User Organization (PNO) provides
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 two PROFIBUS variants:
• PROFIBUS-DP (decentralized peripherals)
Tailored for communication of automation systems and distributed
peripherals.
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
diagnostics 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 permissible
limits for device and cable parameters.

16
Terminal Plate
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.
