4.1 Introduction
This section explains the construction and contents of the XYR 6000 Pressure Transmitter Function Blocks.
4.2 Block description
Block types
Blocks are the key elements that make up the transmitter’s configuration. The blocks contain data (block
objects and parameters) which define the application, such as the inputs and outputs, signal processing and
connections to other applications. The XYR 6000 Transmitter contains the following block types.
Table 4-1 Blocks
Block Type Function
Device
Contains parameters related to the overall field device rather than a
specific input or output channel within it. A field device has exactly one
device block.
AITB
Contains parameters related to a specific process input or output
channel in a measurement or actuation device. An AITB defines a
measurement sensor channel for an analog process variable
represented by a floating-point value. There is one AITB per sensor.
Radio
Contains parameters related to radio communication between the
transmitter and the multimode(s).

Each of these blocks contains parameters that are standard WNSIA-transmitter defined parameters. The
AITB and device blocks contain standard parameters common to all ISA100.11a-compliant transmitters as
well as model-specific parameters. The radio block contains parameters for communication with the
wireless network.
