Data Block Description
4.2.1 Data Block types
Data Blocks are the key elements that make up the sensor'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 WPS
Series Wireless Pressure Sensor contains the following block types.
Block Type
Device
AITB
Radio
Each of these blocks contains parameters that are standard
contain standard parameters common to all ISA100.11a-compliant sensors as well as modelI-specific parameters. The radio block
contains parameters for communication with the wireless network.
The
WDM system
manages the data flow to and from the sensors. It is aware of the relevant data blocks for the various sensors in the
system through the use of the DD files (Device Description Files). As part of the provisioning process, a DD file for the WPS Series
sensors is loaded into the

Function
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.
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.
Contains parameters related to radio communication between the sensor and the multimode(s).
