106 Glossary

online

Describes devices under direct communication. For example, when

RSLogix 5000 is monitoring the program file in a controller.

operating voltage

For inputs, the voltage range needed for the input to be in the On state. For

outputs, the allowable range of user-supplied voltage.

output device

A device, such as a pilot light or a motor starter coil, that is controlled by the

controller.

PTP

Precision Time Protocol. A IEEE-1588 protocol to synchronize independent

clocks running on separate nodes of a distributed measurement and control

system to a high degree of accuracy and precision.

processor

A Central Processing Unit. See CPU.

processor file

The set of program and data files used by the controller to control output

devices. Only one processor file may be stored in the controller at a time.

program file

The area within a processor file that contains the ladder logic program.

program mode

When the controller is not executing the processor file and all outputs are

de-energized.

program scan

A part of the controller’s operating cycle. During the scan the ladder program

is executed and the output data file is updated based on the program and the

input data file.

programming device

Executable programming package used to develop ladder diagrams.
