Functional Description

The FP300 Series converters are used on a FOUNDATION™ fieldbus - FP302, or PROFIBUS-PA - FP303 - systems providing an pneumatic output according to the digital commands coming from the network.

• The FP300 output module main parts are: pilot, servo, pressure sensor, and output control circuit.
• The pneumatic section is based on the pneumatic relay and the baffle nozzle set.
• When the system requires the output pressure value to increase or decrease, the baffle, made by a piezo-electric material, get closer to the nozzle or the reverse. This baffle movement produce a pressure modulation on the pneumatic relay, changing the output pressure. Pressure sensors measure the output pressure and feedback the control circuit to correct the baffle position, if necessary.
• The FP300 is powered by the FOUNDATION™ fieldbus or PROFIBUS PA bus.
• The communication controller manages the databus activity, modulating and demodulating the communication signals.
• The central processing unit (CPU) manages the block operation, self-diagnosis and communications.
• The CPU memory keeps resident software and temporary data. In case of communication failure, the converter has a non volatile memory, in which important data are saved such as calibration, configuration parameters, device identification etc.
• The display controller receives data from the CPU and send them to the LCD according to the user configuration.
• Adjustments and local basic configuration are performed through two switches sensitive to the magnetic tool, with no external contact and no need to open the electronic housing.
• The D/A block converts the CPU signal into a analogic voltage for the control block.
• The output pressure is managed by the control circuitry, which supply a proper voltage for the piezo electric baffle to move in response to the data received from the CPU and compare it with the feedback signal coming from the output pressure sensor.
• The temperature sensor measures the temperatura of the transducer board for possible temperatura compensation, if necessary.
• The data saved into the non volatile EEPROM memory is used for the FP300 re-start procedure.
• The restriction is necessary to a guarantee smooth pressure for the baffle-nozzle set.
• The booster amplifies the pressure changes into the pressure outlet.

Main Characteristics

The FP300 series technology allows an easy interface between the field and the control room, including data transfers, reducing the installation, startup, and maintenance operations costs of industrial processes. The Function Blocks concept makes easier the user programming, who can build up and visually check complex control strategies. The Functions Blocks are flexible enough to allow logical block combinations and recombinations with no need of field wiring changes or any hardware revision.

The FP300 Series allows local basic configuration via a magnetic tool, without opening the electronic housing and without any local push buttons, improving the plant safety.

Using the magnetic tool for basic configuration, the FP300 Series eliminates the handheld configurators, reducing initial installation costs. The FP300 Series is presented for 3 to 15psi or 3 to 30 psi output ranges.

For full configuration, the FP300 Series allows remote connection with software applications according to FOUNDATION™ fieldbus or PROFIBUS-PA standards. Smar offers software applications for both communication protocols, where pneumatic actuators are used or even in old plants migrating from pneumatic to digital technologies.

The FP300 Series is designed for IP66 weather proof installations, explosion proof and intrinsically safe for hazardous areas.

Parameterization and Diagnostics

The FP300 Series converter is available for both FOUNDATION™ fieldbus and PROFIBUS PA communication protocols. The FP300 basic local configuration is easily made with the magnetic tool, and it is not necessary to open the electronic housing for this. For a full configuration FP300 Series, it is necessary to use configuration application software by Smar or from a third party applications and configurators.

Additionally, Smar offers the AssetView application software, a web tool, friendly user interface, available from any internet navigator, at any time, including the FDT/DTM feature. The AssetView is a management software not only dedicated for corrective, preventive and pro-active maintenance tasks, but also provides an easy way to configure field devices.
