ALLEN BRADELY SLC

Programmable Logic Controller

their will be shift in the value when this instruction is used . in this instruction their are some terms that are used that is , File , control , bit address etc

Channel is the number of the RS-232 port (Channel 0)

In this control system, small components are attached to the industrial computer system with the help of a network and control is exercised

A system that does not monitor the output to adjust control. This is typically used on well behaved systems.

Under normal operating conditions, if the set bit corresponds to an output device, the output device will be energized when the rung goes true.If you are using a 5/02, 5/03, 5/04, 5/05 or MicroLogix processor, you can use indexed addresses. If you are using a 5/03 OS302, a 5/04 OS401, or a 5/05 processor, you can use indirect addresses. Output addresses are specified to the bit level.

A housing that holds the CPU and modules. A rack typically refers to a backplane with siding that has slots used to guide the modules into plugs on the backplane.

Random Access Memory is a type of memory where information can be read and stored (written) at any time. Most RAMs memory is volatile and requires a battery to maintain its information.

An area of memory used to store information typically a word.

An EIA standard that specifies electrical, mechanical and functional characteristics for serial communications. It is used for point to point communications less then 15 meters long.

An EIA standard that specifies electrical, mechanical and functional characteristics for serial communications. It is used for multi-point (networked) communications.

A ladder logic term that refers to a series or branch of instructions connected together that drive an output. The term is derived the look of ladder logic which resembles a ladder with rungs.

A numbering system using a word of memory (16 bits) that can display from -32,768 to +32,767.
