108 Glossary
run mode
This is an executing mode during which the controller scans or executes the
ladder program, monitors input devices, energizes output devices, and acts on
enabled I/O forces.
rung
Ladder logic is comprised of a set of rungs. A rung contains input and output
instructions. During Run mode, the inputs on a rung are evaluated to be true
or false. If a path of true logic exists, the outputs are made true. If all paths are
false, the outputs are made false.
save
To upload (transfer) a program stored in memory from a controller to a
personal computer; OR to save a program to a computer hard disk.
scan time
The time required for the controller to execute the instructions in the
program. The scan time may vary depending on the instructions and each
instruction’s status during the scan.
Sealed
Protected from the environment; IEC and NEMA publications define the
degree of protection. International Protection (IP) ratings are two digits the
first of which define protection against solids. These products will be rated “6”
which is totally protected against dust. The second digit defines protection
against liquids. These products will be rated “5”, “6” and “7” which is
protection against water spray and immersion up to 1 meter. NEMA ratings
concern environmental conditions such as corrosion, rust, oil and coolants.
These products will be rated NEMA “4X Indoor”.
SSV
Sensor source voltage. The voltage output on I/O connectors in order to
power attached sensors. SSV in this document should not be confused with
the Logix SSV instruction, used to Set System Value.
SOE
Sequence of Events. Any event that needs to be compared against a second
event.
