Safety Instructions
Operation in Explosive Atmospheres: COMFF 3400X-085 Module
The module is approved for operation in explosive atmospheres.
When installing the product in a hazardous location, observe the information
in the supplements to the certificates and, if applicable, the relevant control
drawings.
Observe all applicable local and national codes and standards for the instal-
lation of electrical equipment in explosive atmospheres. For orientation,
please refer to IEC 60079-14, EU directives 2014/34/EU and 1999/92/EC (ATEX),
NFPA70 (NEC), ANSI/ISA-RP12.06.01.
WARNING! Possible impairment of explosion protection.
• Modules which have already been used shall be subjected to a professional
routine test before they may be operated in another type of protection.
• Prior to commissioning, the operating company must verify the intrinsic
safety in accordance with the installation regulations of IEC60079-14 for
the complete interconnection of all equipment involved, including the
connecting cables.
• The interconnection of Ex and non-Ex modules (mixed assembly) is not
permitted.
• In hazardous locations the device shall only be cleaned with a damp cloth to
prevent electrostatic charging.
Maintenance
The Protos modules cannot be repaired by the user. For inquiries regarding
module repair, please contact Knick Elektronische Messgeräte GmbH & Co. KG
at www.knick.de.

Foundation Fieldbus (FF) Technology
Foundation Fieldbus (FF) is a digital communication system that connects
different field devices over a common cable and integrates them into a control
system. Its application range covers manufacturing, process, and building
automation. As fieldbus standard according to EN 61158-2 (IEC 1158-2) the
Foundation Fieldbus ensures the communication of different devices over one
bus line.
Basic Properties
The “Data Link Layer“ of the Fieldbus Foundation protocol defines 3 device
types:
• The Active Link Master plans all activities as “Link Active Scheduler“ (LAS).
It controls the complete data traffic on the bus. Several Link Masters on one
bus increase safety, but only one is active at a time.
• Basic devices are peripheral devices such as valves, drives, transmitters
or analyzers. They can react acyclically to servicing, configuration and
diagnostic tasks of the master. The Link Master cyclically reads the
measurement data with status.
• Bridges can connect a network from different bus systems.

Foundation Fieldbus (FF) Technology
Bus Communication
Foundation Fieldbus (FF) permits cyclic and acyclic services:
• Cyclic Services - Scheduled Communication:
are used for transmission of measurement data with status information.
The Link Active Scheduler maintains a list of transmission times for all data
in all devices that need to be cyclically transmitted. When it is time to trans-
mit data, the LAS issues a “Compel Data (CD)” start signal to the respective
device. Upon receipt of the “Compel Data” signal, the device broadcasts the
data to all devices on the fieldbus.
• Acyclic Services - Unscheduled Communication:
are used for device configuration, remote maintenance and diagnostics
during operation.
All devices are given the chance to send acyclic (unscheduled) messages
between transmissions of cyclic (scheduled) data. The LAS grants permis-
sion to a device to broadcast acyclic messages by issuing a “Pass Token
(PT)” message. Upon receipt of the “Pass Token”, the device starts data
transmission.
