• 5 Transducer Blocks
– Pressure Transducer Block (TRD)
This Block supplies the output variables PRIMARY_VALUE and SECONDARY_VALUE. It
contains all the parameters to configure the measuring device for the measuring task
such as measuring mode selection, linearization function and unit selection.
– Service Transducer Block
This Block supplies the output variables COUNTER P_PMAX, PRESSURE_1_ MAX_
RESETABLE and PRESSURE_1_AFTER_DAMPING. It also includes all the counters for
measuring range overshoot/undershoot for pressure and temperature, minimum and
maximum measured values for pressure and temperature and the HistoROM function.
– DP Flow Block
This Block supplies the output variable TOTALIZER_1_VALUE/TOTALIZER 1. It
contains all the parameters that are needed to configure this totalizer.
– Display Transducer Block
This Block does not return any output variables. It contains all the parameters for
configuring the onsite display such as DISPLAY_CONTRAST.
– Diagnostic Transducer Block
This Block does not return any output variables. It contains
– the simulation function for the Pressure Transducer Block
– parameters to configure the alarm response
– parameters to set the user limits for pressure and temperature.
• 9 function blocks
– 3 Analog Input Blocks (AI)
– Discrete Output Block (DO)
– Discrete Input Block (DI)
– PID Block (PID)
– Arithmetic Block (ARB)
– Signal Characterizer Block (SCB)
– Input Selector Block (ISB)
– Analog Alarm Block (AALB)
– Integrator Block (IT)
In addition to the pre-instantiated blocks already mentioned, the following blocks can also
be instantiated:
• 3 Analog Input Blocks (AI)
• 1 Discrete Output Block (DO)
• 1 PID Block (PID)
• 1 Arithmetic Block (ARB)
• 1 Signal Characterizer Block (SCB)
• 1 Input Selector Block (ISB)
• 1 Analog Alarm Block (AALB)
• Integrator Block (IT)
A total of 20 blocks can be instantiated in Deltabar S altogether, including the blocks already
instantiated. For instantiating blocks, see the appropriate Operating Instructions of the
configuration program used.
Hauser Guideline BA00062S.
The guideline provides an overview of the standard function blocks that are described in
FOUNDATION Fieldbus Specifications FF 890 - 894.
It is designed to help operators use the blocks implemented in the Hauser field
devices.
