1588
IEEE1588-2008 is a protocol to synchronize independent clocks running on
separate nodes of a distributed measurement and control system to a high
degree of accuracy and precision. Provides accurate real-time (Real-World
Time) or Universal Coordinated Time (UTC) synchronization.
address
A character string that uniquely identifies a memory location. For example,
I:1/0 is the memory address for the data located in the Input file location
word1, bit 0.
application
1) A machine or process monitored and controlled by a controller.
2) The use of computer- or processor-based routines for specific purposes.
baud rate
The speed of communication between devices. All devices must communicate
at the same baud rate on a network.
bit
The smallest storage location in memory that contains either a 1 (ON) or a 0
(OFF).
block diagrams
A schematic drawing.
Boolean operators
Logical operators such as AND, OR, NAND, NOR, NOT, and Exclusive-OR
that can be used singularly or in combination to form logic statements or
circuits. Can have an output response of T or F.
branch
A parallel logic path within a rung of a ladder program.
CIP
Common Industrial Protocol. The application layer protocol specified for
EtherNet/IP, the Ethernet Industrial Protocol, as well as for ControlNet and
DeviceNet. It is a message-based protocol that implements a relative path to
