2 smar Description The LD302 is from the first generation of Fieldbus devices. It is a transmitter for differential, absolute and gauge pressure, level and flow measurements. It is based on a field-proven digital capacitive sensor that provides reliable operation and high performance. The digital technology used in the LD302 enables the choice of several types of transfer functions, an easy interface between the field and the control room, superior accuracy, stability and several interesting features that considerably reduce the installation, operation, and maintenance costs. The LD302 is part of Smar s complete 302 series of Fieldbus devices. Fieldbus is a complete system enabling distribution of the control function to equipment in the field, interconnecting several devices and the user can build control strategies suitable for his application by linking the function blocks. In order to be user friendly, the function block concept was introduced. The user may now easily build and overview complex control strategies. Another advantage is added flexibility, the control strategy may be edited without having to rewire or change any hardware. The need for implementation of Fieldbus in small as well as large systems was considered when developing the entire 302 series of Fieldbus devices. They have the common features of being able to act as a master on the network and be configured locally using a magnetic tool, eliminating the need for a configurator or console in many basic applications. Function Blocks Table BLCK RES RESURCE This block contains data that is specific to the hardware that is associated with the resource. TRD TRANSDUCER BLCK This block converts the primary variables of the function blocks will be displayed in the device LCD panel.. DSP DISPLAY TRANSDUCER This block configures what process variables of the function blocks will be displayed in the device LCD panel. Accepts any engineering units. DIAG DIAGNSTICS TRANSDUCER It provides online measurement of block execution time, check of links between blocks and other features. AI ANALG INPUT This block takes the input data from the transducer block and makes it available to other function blocks. It has scaling conversion, filtering, square root and low cut. PID PID CNTRL This standard block has a lot of valuables features as setpoint treatment (value and rate limiting), filtering and alarm on PV, feed-forward, output tracking and others. F57

3 APID ARTH INTG ISEL CHAR AALM TIME ADVANCED PID It has all the standard features plus: bumpless or hard transfer from a manual mode to an automatic mode, bias. Adaptive gain, PI sampling, dead-band for error, special treatment for error, ISA or parallel algorithm. ARITHMETIC This calculation block provides some pre-defined equations ready for use in applications as flow compensation, HTG, ratio control and others. INTEGRATR It integrates a variable in function of the time. There is a second flow input that may be used for the following applications: net flow totalization, volume/ mass variation in vessels and precise flow ratio control. INPUT SELECTR This block has four analog inputs that may be selected by an input parameter or according to a criterion as first good, maximum, minimum, middle and average. SIGNAL CHARACTERIZER It has capability for two signal characterization based on the same curve. The second input has an option for swapping x to y, providing an easy way to use the inverse function, that may be used in signal characterization of read-back variables. ANALG ALARM This alarm block has dynamic or static alarm limits, hysteresis, temporary expansion of alarm limits on step setpoint changes to avoid nuisance alarms, two levels of alarm limits and delay for alarm detection. TIMER This block has four discrete inputs that are processed by combination logic. The selected timer processing type operates on the combined input signal to produce a measurement, delay, extension, and pulse or debounce. FB DEVICES LLAG SDL LEAD-LAG This block provides dynamic compensation of a variable. It is used normally in a feed-forward control. UTPUT SELECTR / DYNAMIC LIMITER It has two algorithms: utput selector selection of output by a discrete input. Dynamic limiter this algorithm was developed specially for double cross limit in combustion control. CT DENS CNSTANT It provides analog and discrete output parameters with constant values. DENSITY This block has a special algorithm to calculate the density in different types of engineering units: Plato degree, INPM and others. LD302 F5
