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.

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

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.
