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 SmartLine Wireless Transmitter
contains the following block types.
Block Type
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
BITB or actuation device. An AITB defines a measurement sensor channel for an analog process
BOTB variable represented by a floating-point value. A BITB defines a measurement sensor
channel for a digital/binary process variable. A BOTB defines an output channel for a
digtal/binary process variable.
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, BITB, BOTB 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.
