This section covers basic configuration procedures for the Rosemount 5900S
Radar Level Gauge with F
For detailed information about F
blocks used in the Rosemount 5900S Series, refer to Appendix C: Foundation
Fieldbus Block Information and the F
(Document No. 00809-0100-4783).
Function blocks within the fieldbus device perform the various functions
required for process control. Function blocks perform process control
functions, such as analog input (AI) functions and proportional-integral
derivative (PID) functions. The standard function blocks provide a common
structure for defining function block inputs, outputs, control parameters,
events, alarms, and modes, and combining them into a process that can be
implemented within a single device or over the fieldbus network. This
simplifies the identification of characteristics that are common to function
blocks.
In addition to function blocks, fieldbus devices contain two other block types
to support the function blocks. These are the Resource block and the
Transducer blocks.
The Resource block contains the hardware specific characteristics associated
with a device; they have no input or output parameters. The algorithm within a
resource block monitors and controls the general operation of the physical
device hardware. There is only one resource block defined for a device.
Transducer blocks connect function blocks to local input/output functions.
They read sensor hardware and write to effector (actuator) hardware.
Resource Block
The Resource block contains diagnostic, hardware, electronics, and mode
handling information. There are no linkable inputs or outputs to the Resource
Block.
Measurement Transducer Block (TB1100)
The Measurement Transducer Block contains device information including
diagnostics and the ability to configure, set to factory defaults and restart the
level gauge.
Register Transducer Block (TB1200)
The Register Transducer Block allows a service engineer to access all
database registers in the device.
Advanced Configuration Transducer Block (TB1300)
The Advanced Configuration Transducer Block contains parameters for setup
and configuration of the advanced level measurement and echo tracking
functions.
Volume Transducer Block (TB1400)
The Volume Transducer Block contains parameters for configuration of
volume calculations.
