Note!
A detailed description of the function groups, functions and parameters is given in the
documentation "BA00245F – Description of the Instrument Functions" on the enclosed CD-ROM.
11.3 Block model of the Levelflex M
The Micropilot M contains the follwoing blocks:
• Resource Block (RB2)
see Operating Instructions BA013S/04/EN: "FOUNDATION Fieldbus - Overview"
• Sensor Block (TBGRL)
contains the parameters relevant to the measurement of the Levelflex M
• Diagnostic Block (DIAG)
contains the diagnostic parameters of the Levelflex M
• Display Block (DISP)
contains the configuration parameters for the display module VU331
• Analog-Input-Block 1 bzw. 2 (AI)
scale the signal of the Transducer Block and transmit them to the PLCS
• PID Block (PID)
see Operating Instructions BA013S/04/EN: "FOUNDATION Fieldbus - Overview"
• Arithmetic Block (AR)
see Operating Instructions BA013S/04/EN: "FOUNDATION Fieldbus - Overview"
• Input Selector Block (IS)
see Operating Instructions BA013S/04/EN: "FOUNDATION Fieldbus - Overview"
• Signal Characterizer Block (SC)
see Operating Instructions BA013S/04/EN: "FOUNDATION Fieldbus - Overview"
• Integrator Block (IT)
see Operating Instructions BA013S/04/EN: "FOUNDATION Fieldbus - Overview"
11.3.1 Default Block configuration
The input and output variables of the blocks can be interconnected by a network configuration tool
(e.g. NI-Fieldbus configurator). The figure below shows, how these connections are set by default.
