Initialization and zero calibration of the positioner
Resource Block (RES)
The Resource Block (RES) describes characteristics of the fieldbus device, such as the device
name, manufacturer number and serial number. There is only one Resource Block in a de
-
vice.
Function Blocks (FB)
Function Blocks are responsible for the way a
F
OUNDATION
™
fieldbus device works. A
F
OUNDATION
™
fieldbus application can be configured by linking the input and output
parameters of Function Blocks.
The Type 3730-5 Positioner includes the following Function Blocks:
−
1x Analog Output Function Blocks (AO FB); execution time: 30 ms
−
1x Analog Input Function Blocks (AI FB); execution time: 30 ms
−
2x Discrete Output Function Blocks (DO FB); execution time: 30 ms
−
2x Discrete Input Function Blocks (DI FB); execution time: 20 ms
−
1x Proportional Integral Derivative Function Block (PID); execution time: 40 ms
Transducer Blocks (TRD)
Each AI or AO Function Block has a Transducer Block which contains all data and de
-
vice-specific parameters to link the device to the process value (sensor or final control ele
-
ment).
The following Transducer Blocks (corresponding to the Function Blocks) are implemented:
−
1x Advanced Positioner Transducer Block (AO TRD)
−
1x Analog Input Transducer Block (AI TRD)
−
2x Discrete Output Transducer Blocks (DO TRD)
−
2x Discrete Input Transducer Blocks (DI TRD)

Initialization and zero calibration of the positioner
Both an initialization and a zero calibration can be started over the XD_COMMAND param
-
eter of the AO Transducer Block. The relevant parameters for a MAX/NOM initialization and
the diagnostic functions of EXPERTplus are listed below (
