Explosion protection in accordance with FM (USA)

Special conditions for use

● For type of protection "db": When you use the device as partition wall device in zones that require EPL Ga, isolate the non-

intrinsically safe circuit safely from ground, e.g.: through a SELV circuit.

● For type of protection "ec": Isolate the non-intrinsically safe circuit safely from ground, e.g.: through a SELV circuit that

ensures transient protection up to 140% of the nominal voltage.

● Mount the device so that the enclosure is not exposed to any intense electrostatic charging processes.

● To prevent electrostatic charging in hazardous areas, clean the outside of the enclosure using a cloth moistened with

water.

SIMATIC PDM

B.1.1

Overview SIMATIC PDM

SIMATIC PDM (Process Device Manager) is a general-purpose, manufacturer-independent

tool for the configuration, parameter assignment, commissioning, diagnostics and

maintenance of intelligent field devices and field components. Follow-up installations and

additional information on SIMATIC PDM are available on the Internet at SIMATIC PDM

(www.siemens.com/simatic-pdm ).

SIMATIC PDM monitors the process values, alarms and status signals of the device. It allows

you to display, compare, adjust, verify, and simulate process device data; also to set schedules

for calibration and maintenance.

For information on, for example, how to install and integrate devices, commission the software,

see Operating Manual 'Help for SIMATIC PDM'. The manual is delivered with SIMATIC PDM

software. Once the SIMATIC PDM is installed on your computer you find the manual under:

Start > All programs > Siemens Automation > SIMATIC > Documentation. Link at our website:

SIMATIC PDM instructions and manuals (https://support.industry.siemens.com/cs/ww/en/ps/

16983/man).

Note

Field device parameters

● For a list of parameters and additional information, consult section "Parameter assignment

(Page 101)".

● The field device remains in measurement mode during the time you configure the field

device.

B.1.2

Check SIMATIC PDM version

Procedure

1. Go to SIMATIC PDM download (http://www.siemens.com/simaticpdm/downloads ).

2. Check the support page to make sure you have:

- The latest version of SIMATIC PDM

- The most recent Service Pack (SP)

- The most recent hot fix (HF)

Deactivate buffers when connecting via serial modem

Introduction

This deactivation is required to align SIMATIC PDM with the HART modem when using a

Microsoft Windows operating systems.

Deactivating buffers is not necessary when connecting via USB.

Condition

Glossary

ATEX

ATEX is an abbreviation of the French term "Atmosphère explosible" (potentially explosive

atmosphere). ATEX stands for both EC directives in the area of explosion protection: ATEX

product directive 94/9/EC and ATEX operating directive 1999/92/EC.

Auxiliary power supply

Auxiliary power supply refers to an electrical supply or reference voltage which some electrical

circuits require apart from the standard supply. The auxiliary power supply can, for example, be

specially stabilized, have a particular level or polarity and/or other properties which are

important for the correct functioning of switch components.

Auxiliary voltage

→ Auxiliary power supply

Dangerous failure

Failure with the potential to switch a safety-instrumented system to a hazardous or non-

functioning safety state.

EEPROM

EEPROM (Electrically Erasable Programmable Read-Only Memory): a non-volatile, electronic

memory module.

EEPROMs are often used where individual bytes of data (e.g. configuration data or runtime

meters) change over time and must be stored safely in the event of a mains power failure.

Failure/Fault/Error

Failure:

A resource is no longer capable of executing a required function.

Fault/Error:

Undesired state of a resource indicated by its incapability of executing a required function.

Fault/Error

→ Failure/Fault/Error

Final controlling element

Converter that converts electrical signals into mechanical or other non-electric variables.

Glossary

Fingerprint

Numerical value generated by the device when you start safety validation via the "Functional

Safety" wizard. By comparing the fingerprint, you determine whether or not the device and the

safety-related parameters have changed erroneously during activation of the functional safety.

Firmware

Firmware (FW) is software that is embedded on a chip in electronic devices - in contrast to

software which is saved on hard disks, CD-ROMs or other media. These days, firmware is

mostly stored in a flash memory or EEPROM.

Firmware usually contains the elementary functions for controlling the device, as well as input

and output routines.

Frequency shift keying

Frequency shift keying is a simple form of modulation, where the digital values 0 and 1

modulate the actual current signal by means of two different frequencies.

Frequency Shift Keying (FSK)

→ Frequency shift keying

HART

HART (Highway Addressable Remote Transducer) is a standardized, widely used

communications system used to structure industrial fieldbusses. The communications system

provides digital communications for multiple participants (field devices) via a common databus.

HART is based especially on the equally widely used 4/20 mA standard for the transfer of

analog sensor signals. The cabling from existing older systems can be used directly and both

systems operated in parallel.

HART specifies several protocol levels in the OSI model. It facilitates the transfer of process

and diagnostics data and control signals between field devices and high-level control systems.

Standardized parameter sets can be used for the manufacture-independent operation of all

HART devices.

Typical applications include transmitters for measuring mechanical and electrical dimensions.

Non-volatile memory

Risk

Combination of the probability of damage occurring and the extent of the damage.

Glossary

Safety function

Defined function executed by a safety-instrumented system with the objective of attaining or

maintaining a safe system state by taking a defined hazardous incident into account.

Example:

Limit pressure monitoring

Safety Integrity Level

→ SIL

Safety-instrumented system

A safety-instrumented system (SIS) executes the safety functions that are required to achieve

or maintain a safe state in a system. It consists of a sensor, logic unit/control system and final

controlling element.

Example:

A safety-instrumented system is made up of a pressure transmitter, a limit signal sensor and a

control valve.

Sensor

Converter that converts mechanical or other non-electric variables into electrical signals.

SIL

The international standard IEC 61508 defines four discrete safety integrity levels (SIL) from SIL

1 to SIL 4. Each level corresponds to a probability range for the failure of a safety function. The

higher the SIL of the safety-instrumented system, the higher the probability that the required

safety function will work.

The SIL which can be achieved is determined by the following safety-instrumented

characteristics:

● Average probability of failure on demand (PFD_AVG)

● Hardware fault tolerance (HFT)

● Safe failure fraction (SFF)

Spread

Ratio of the set measuring span to the maximum set measuring span.

Total error

Total Error is sum of Total Performance and the long-term stability.
