Revision 1.0
The detection of a block leaving a state and when it returns to that state.
One of the standard function blocks define by the Foundation Modbus
Absolute Pressure
A software program that interacts with blocks, events and objects. One
application may interface with other applications or contain more than one
application.
American Wire Gauge
A logical software unit that makes up one named copy of a block and the
associated parameters its block type specifies. It can be a resource block,
transducer block or a function block.
A step-in system design: selecting functional units, assigning their locations
and identifiers, and defining their interconnections.
A physical entity capable of performing one or more specific functions.
Examples include transmitters, actuators, controllers, operator interfaces.
Description of FBAPs within a device. Files that describe the software objects
in a device, such as function blocks and parameters. The DD binary are
created by passing DD source files through a standard tool called a tokenizer.
A standardized programming language (similar to C) used to write device
description source files.
The Physical Device Tag of the device as specified in the Foundation Modbus
specifications.
Differential Pressure
Electrically Erasable Programmable Read Only Memory
Electromagnetic Interference
An instantaneous occurrence that is significant to scheduling block execution
and to the operational (event) view of the application.
A Modbus-compatible device that contains and executes function blocks.
Field Termination Assembly
An executable software object that performs a specific task, such as
measurement or control, with inputs and outputs that connect to other function
blocks in a standard way.
The part of the device software that executes the blocks (function, transducer,
or resource blocks).
Gauge Pressure
High Pressure (also, High Pressure side of a Differential Pressure Transmitter)
Hertz
Inches of Water
In-Line Gauge Pressure
A device which is responsible for keeping a link operational. The LAS executes
the link schedule, circulates tokens, distributes time messages and probes for
new devices.
Low Pressure (also, Low Pressure side of a Differential Pressure Transmitter)
Lower Range Limit
Lower Range Value
