Glossary
low-side output
An output that provides a switched ground voltage to an external load.
module address
The binary address of the DPS70, as determined by the harnessing.
multiplexing
Transmitting multiple messages simultaneously over one channel in a local area
network.
network fault flag
A special flag available in ladder logic that indicates a network problem exists
(when master power is inactive and ladder logic references VMM(s) that are not
available, or VMM(s) do not contain the same version of ladder logic).
Nyquist criterion
A theorem stating that a reconstructed signal will match the original signal
provided that the original signal contains no frequencies at or higher than one-half
the sampling frequency
open load
The disconnection of a load from an output, often because of a broken or worn
wire or connector pin.
overcurrent
A fault state that occurs when a load draws more current than specified for an
output, which results in the output shutting down to protect the circuitry of the
product.
overvoltage
A situation in which the voltage in a circuit rises above its upper design limit.
panel-mounted
A device mounted into a flat panel that has a cutout in the shape of the device.
PID controller
See
proportional-integral-differential (PID) controller
.
power control input
A digital input that is used to turn on the product. When the input is active, the
product turns on and operates in normal mode; when the input is inactive, the
product powers down and will not operate.
