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.

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.

9
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.

Terminal Plate COMFF 3400-085 Module:
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.

11
1) Switch off the power supply to the device.
2) Open the device (loosen the 4 screws on the front).
3) Plug the module into the slot (D-SUB connector),
see figure.
4) Tighten the module's fastening screws.
5) Connect the signal lines (see next page).
6) Check whether all connections are correctly wired.
7) Close the device by tightening the screws on the front.
8) Switch on the power supply.
CAUTION! Incorrect measurement results.
Incorrect parameter setting, calibration or adjustment may result in incorrect
measurements being recorded. Protos must therefore be commissioned by a
system specialist, all its parameters must be set, and it must be fully adjusted.
Installing the Module
CAUTION! Electrostatic discharge (ESD).
The modules' signal inputs are sensitive to electrostatic discharge.
Take measures to protect against ESD before inserting the module and wiring
the inputs.
Note: Strip the insulation from the wires using a suitable tool to prevent dam-
age.

Communication Model
See diagram on previous side
All variables and parameters of the transmitter are assigned to blocks.
Resource Block (RB)
Describes the transmitter characteristics (manufacturer, device name,
operating status, general status).
Analog Input Block (AI)
2 x 4 Analog Input Function Blocks provide for cyclic transmission of measured
values (currently measured value with status, alarm limits, freely selectable
process variable from up to 2 measuring modules).
Analog Input Transducer Block (AI TB)
Provides for acyclic data transmission. Calibration, configuration, and main-
tenance commands coming from the control station are processed in the
Transducer Block. The sensor signal is first preprocessed in the Transducer
Block. From here, the measured value is sent to the Analog Input Blocks where
it can be further processed (limit values, scaling).
Connections (Channels)
The communication model shows the channel numbers for connecting the
function blocks to the Transducer Blocks.

Offline Configuration
The AI blocks are divided into two groups (AI Transducer Blocks) which are
each assigned to one measuring module. This allows control of functions in the
measuring modules. If there is only one measuring module, both AI TBs can be
assigned to the same module so that they can output more measured values
cyclically. In this exemplary configuration there is a PH 3400-032 module in
slot[I], an OXY 3400-062 module in slot [II], and the COMFF 3400-085 module in
slot [III].

Example 2:

therefore all process variables of the Oxy
module are available for AI5 to AI8.
Bus communication on the Foundation Fieldbus can only function properly
when during online configuration the blocks in the control system are set in
accordance with the AI-TB configurations selected in the device configuration.
The modular Protos does not allow permanent assignment of process variables
to AIs - any available module can be located in one of the three slots, which
cannot be recognized from the control system.
Therefore you cannot preconfigure the device offline per DD from the control
system.

AI TB 1 (AI Transducer Block)
As an example, this block was assigned to the Module I
(measuring module, pH). All process variables available from
this module can be assigned to the AI channels.

Commissioning and Configuration
Initial Commissioning
1. Supply the device with power.
2. Open the configuration program of the control system.
3. Load CFF file and DD.
After the first connection establishment, the device answers as follows:
Device ID
4. Assign the desired name (PD_TAG) to the field device.
Setting the Resource Block (RB) parameters
5. Set the MODE_BLK. TARGET to Auto.
Setting the Analog Input Block (AI) parameters
6. Set MODE_BLK. TARGET to OOS (Out Of Service).
7. Select the desired process variable from the CHANNEL parameter
(Observe parameter setting of FRONT module!).
8. Select the unit belonging to the process variable from the
XD_SCALE parameter.
9. Select the unit belonging to the process variable from the

you can graphically connect the function blocks and then load the system
configuration in the device.
12. Download all data and parameters to the field device.
13. Set the target modes of all Analog Input Blocks to “Auto“.
