1.3 Description
The ICoT 5500 (ICoT PA) provides intelligence for the
control valve through a microprocessor-based system
utilizing the PROFIBUS PA protocol. Accurate
measurement of valve stem position, input signal,
actuator pressure, cycle time and cycle count data can
be recorded during normal operation.
The positioner has a local LCD display, which indicates
valve position, set-point in percentage open, calibration
status, alarms status and whether the ICoT is in local or
fieldbus control. If a failure condition occurs, an error
message is displayed on the local LCD display and
communicated to the Host system via fieldbus.
The ICoT PA is an electro-pneumatic servo system that
continuously controls the position of a valve based on
the fieldbus input signal. The ICoT senses valve position
via a non-contact Hall Effect sensor and controls valve
position through a current to pressure transducer
The ICoT PA is a two wire, polarity insensitive
instrument that receives both signal and power from the bus. Current consumption of the
ICoT is 12.5mA with an operating voltage of 9 – 32 Vdc.
The ICoT PA version allows calibration and access to on-line diagnostic information via
hand-held terminal or through software.
A set of hermetically sealed non-contact limit switches is an option that can be integrally
supplied with the ICoT PA.

1.4 Principles of Operation
1.4.1 Enclosures
The ICoT PA Positioner can be built in three different enclosure materials: engineered
resin, 316 stainless steel and aluminum.
1.4.2 Position Feedback
Non-Contact Position Feedback
To provide consistently accurate performance information, all linkages, levers and
connecting rods, from the positioner to the control valve have been eliminated from
the design. Valve position sensing is performed totally by non-contacting means
based upon characterization of magnetic flux strength as a function of position.

Remote Position Control
Since valve position feedback to the ICoT PA positioner is
accomplished by non-contacting means, the ICoT PA has
the unique ability to be mounted remotely (up to a distance
of 50 feet, optionally 150 feet) from the device it is
controlling. In the event the control valve is located in a high
vibration or extremely corrosive environment, the non-
contact position feedback feature allows for isolated
placement of the positioner.
1.4.3 Local Graphic LCD
The ICoT PA positioner is supplied with a digital
communication interface PA or a 3-button keypad interface. Both
versions are furnished with a graphic LCD, and allow for automated
calibration of the positioner. The local LCD provides a multitude of
onsite diagnostic information. The LCD shows input current, set-
point and current position. The values displayed range from 0.0% to
100.0%. Displayed resolution is in 0.1% increments, however,
internal calculations are maintained at higher precision.
1.5 Special Features
On-Board Sensors
The ICoT PA positioner has the capability to monitor its operation. If an error or failure condition
occurs, it will be displayed on the local LCD, or if the positioner is supplied with a PA interface,
the error codes will be displayed on a hand held terminal or a PC maintenance station.
Note: Error codes are denoted on a label affixed to the LCD flip-up protective cover.
Local Keypad
The positioner is provided with a ruggedized 3-button keypad. The keypad can be
used for zero and span adjustments, as well as valve characterization and gain
adjustments.
Intelligent Calibration via PA
The parameters of the ICoT PA-IS positioner are fully accessible via PROFIBUS.
Manual or Automatic calibration can be initiated via the bus and parameters for altering internal
servo loop tuning are fully configurable. In this manner, positioner performance may be
optimized with a wide combination of valves and actuators via PROFIBUS.
Negligible Bleed
Designed to consume the least possible amount of control air at steady state, the ICoT 5500
Series positioner can greatly reduce the air consumption of your process and reduce the
demand on instrument air compressors. To increase reliability, the ICoT PA employs a patented

PROFIBUS-related definitions1
GSD
A TXT file to inform to help the configuration system to know the capability of each device.
The GSD file name has the identification number (ident number), and each PROFIBUS
device type has a unique ident number. If you know the ident number, you can find easily
the GSD file.
Cyclic Data Transfer
At device startup the master configured the data to be exchange cyclic. The GSD provide
the information needs for the master to configure the cyclic data transfer automatically.
Acyclic Data Transfer
Asynchrony data transfer. The master requests a data and receives it from the slave.
Basic Device
A Basic Device is any device not having the capability to communicate on PROFIBUS
fieldbus segment.
Bus
A set of segments (DP and PA) connected via repeaters or couplers. Allow up to 128
devices.
Communications Stack
It is a layered software supporting communication between devices. A Communications
Stack is device communications software, which provides encoding and decoding of User
Layer messages, deterministic control of message transmission, and message transfer.
Device Coupler
A device coupler is a physical interface between a PROFIBUS DP segment and
PROFIBUS PA segment.

Electronic Device Description (EDD) provides an extended description of each object in the
device, and includes information needed for a control system or host to understand the
meaning of data. Used by the Siemens PDM.
FISCO
Fieldbus Intrinsic Safe COncept. Allows more power to an IS segment for approved FISCO
devices, allowing for more devices per IS segment.
FNICO
Fieldbus Non-Incendive COncept allows more power to a fieldbus segment in a Zone 2
Area, thus enabling more devices per segment than is possible with a FISCO solution.
Interoperability
Interoperability is the capability for a device from one manufacturer to interact with that of
another manufacturer on a fieldbus network without loss of functionality.
Intrinsic safety (IS)
Intrinsic Safety is a protection method for safe operation of electronic equipment in
explosive atmospheres even under irregular operating conditions. It assures that the
available electrical and thermal energy in the system is always lower than the amount that
could cause ignition of the hazardous atmosphere.
Mode
Control block operational condition, such as manual, automatic, or cascade.
Segment
A Segment is a section of a PROFIBUS fieldbus terminated in its characteristic impedance.
Segments can be linked by Repeaters to form a longer fieldbus. Each segment can include
up to 32 H1 devices.
Spur
A Spur is a PA branch line connecting to the Trunk that is a final circuit. A Spur can vary in
length from 1 m (3.28 ft.) to 120 m (394 ft.).
Function Block (FB)
Function Blocks (FBs) are built into fieldbus devices as needed to achieve the desired
control functionality. Automation functions provided by FBs include Analog Input (AI),
Analog Output (AO), Discrete Input (DI) and Discrete Output (DO).
Device Type Manager
Device Type Manager is a device specific software component provide by the device
manufacture together with its device. This software is implemented following the FDT
specification.
FDT
FDT is a technology where it standardizes the communication between the device and the
application to provide sophisticated views of the device data for configuration, maintenance
and operation.

Step 2. Press fit the inner beacon to the inner beacon coupler. The inner beacon needs to
be properly oriented. Use the symbols on the top of the inner beacon to mount as shown in
Condition 1 or Condition 2. (See Figure 5-2). Condition 1 and Condition 2 show the
placement of the inner beacon with respect to the positioner housing while the actuator is in
the fail position.
Step 3. Mount the positioner to the bracket. As stated in Step 2 make sure that the
positioner is mounted in a fashion that properly orients it with respect to the inner beacon.
Condition 1: Actuator fails in a clockwise direction.
