PLC 2 Assignment Questions Flashcards
What are CONNECTIONS in a ControlLogix system?
Connections stablish a communication link between two
devices.
How many connections can a 1756-L63 processor make? How many can a 1756-L7
series make?
250, 500
How many connections can a 1756-ENBT Ethernet module make?
TCP - 62
CIP - 128
When an I/O module is added to a ControlLogix application, how many connections
are used?
When an I/O module is added to a ControlLogix application, typically, it consumes one
connection per module.
What is the maximum number of digital I/O that can be interfaced to one
ControlLogix processor?
128 000
What is the maximum number of analog I/O that can be interfaced to one
ControlLogix processor?
4,000
What is a produced tag?
A tag that a controller makes available for use by other controllers.
Multiple controllers can simultaneously consume (receive) the data. A produced tag
sends its data to one or more consumed tags (consumers) without using logic
What is a consumed tag?
A tag that receives the data of a produced tag. The data type of the
consumed tag must match the data type (including any array dimensions) of the produced
tag. The RPI of the consumed tag determines the period at which the data updates.
When you create a produced tag, what type of data can it be?
It can be of various data types, including DINT, REAL, STRING, ARRAY, UD, and more.
What is the maximum number of bytes that can be produced?
500 bytes
Which processor determines how often the data is shared? Is it the producing
processor or the consuming processor?
Consuming processor gets data at RPI (as long as it’s within the min/max RPI set by the producer.)
