Safety Information & Guidelines
This section contains information that must be read and understood by all
persons installing, using, or maintaining this equipment.
Safety
Considerations
Failure to follow appropriate safety procedures or inappropriate use of the
equipment described in this manual can lead to equipment damage or
injury to personnel.
Any person working with or on the equipment described in this manual is
required to evaluate all functions and operations for potential safety hazards
before commencing work. Appropriate precautions must be taken as
necessary to prevent potential damage to equipment or injury to personnel.
The information in this manual is designed to aid personnel to correctly
and safely install, operate, and/or maintain the system described; however,
personnel are still responsible for considering all actions and procedures for
potential hazards or conditions that may not have been anticipated in the
written procedures. If a procedure cannot be performed safely, it must not
be performed until appropriate actions can be taken to ensure the safety
of the equipment and personnel. The procedures in this manual are not
designed to replace or supersede required or common sense safety practices.
All safety warnings listed in any documentation applicable to equipment
and parts used in or with the system described in this manual must be read
and understood prior to working on or with any part of the system.
Failure to correctly perform the instructions and procedures in this
manual or other documents pertaining to this system can result in
equipment malfunction, equipment damage, and/or injury to personnel.

Chapter 1
Product Overview
Introduction The Thermo Scientific LevelPRO is designed to provide reliable and
accurate level measurements. With FOUNDATION™ fieldbus, the gauge
also provides users with access to control or program parameters via a host
system.
The gauge consists of a source head containing the radioisotope source and
the detector-transmitter. The radioisotope source emits gamma radiation
that passes through the process material. The detector measures the energy
of the radiation arriving at the detector after passing through the process
material (and vessel walls). The gauge determines the level of the process
material by measuring the amount of radiation arriving at the detector,
which varies with the level of the process material.
Note This guide contains information specific to applications using the
LevelPRO with FOUNDATION fieldbus. For information on the standard
LevelPRO, reference the LevelPRO user guide (P/N 717778). ▲
Fieldbus
Overview
Fieldbus is an all-digital communication system between devices on the
bus. The LevelPRO with FOUNDATION fieldbus provides the following:
●Execution of control functions (algorithms) in the actual device
●Device registration with the Fieldbus Foundation™, ensuring
compatibility with the devices of other systems
●Ability to configure using device specific device description (DD)
●Ability to send data directly between devices
Note This manual assumes a working knowledge of FOUNDATION fieldbus
terminology and practices. For additional information on FOUNDATION
fieldbus, visit http://www.fieldbus.org. ▲
Thermo Fisher Scientific LevelPRO with FOUNDATION™ fieldbus Application Guide 1-1

Product Overview
Fieldbus Overview
A FOUNDATION fieldbus network consists of links and devices. A link is the
serial bus that connects the devices on the network. There are three types of
devices:
Links and Devices
●Link master: The LevelPRO with FOUNDATION fieldbus has link
master capabilities. This device type controls communications traffic on
a link and prevents multiple devices from communicating data at the
same time. A link master may also be the Link Active Scheduler (LAS),
which is the device that is currently controlling access to the fieldbus. A
fieldbus network may have more than one link master per link, but
there may be only one LAS at a time.
●Basic device: This device type can communicate on the fieldbus
network, but it cannot become the LAS.
●Bridge: This device type connects two or more links in a fieldbus
network.
A device is identified by its device tag and device ID. The device tag is the
unique name you assign to it, and the device ID is a unique identifier
assigned by the manufacturer. The device ID cannot be changed.
Blocks Blocks allow you to configure and control the fieldbus gauge. A block is
identified by its block tag, which is similar to the device tag. The block tag
uniquely identifies the block on the network.
Linkages connect two blocks and enable the transfer of data from one
function block to another. The LevelPRO supports the following blocks:
●One resource block (RB): Contains device information, such as the
device tag and device ID.
●One transducer block (TB): Allows you to configure or view setup
parameters and access system diagnostic tools.
●One analog input block (AI): Makes manufacturer's input data
available to other functions at its output.
The figure below illustrates the default interconnections of the blocks.
