Extraneous electrical signals. Noise can be produced by such external sources as power lines,
generators, motors, transformers, and electrical storms. It can also result from internal sources,
such as resistors, capacitors, and semiconductors.
Pamux
A high-speed, high-density distributed I/O system that accommodates both digital and analog brain
boards and I/O modules. Pamux supports up to 32 stations containing up to 512 I/O points. A Pamux
bus can extend up to 500 feet from a host computer or other programming device. Pamux is ideal
for low-noise applications, such as robotics and numerical control.
point
A single input/output data access location. An I/O point can accept either input data (read from a
field device) or output data (to be transmitted to a field device). Most I/O modules feature one point
of I/O; an exception is quad pak modules, which feature four points of I/O. Also called channel.
port
A communication connection on a computer or controlling device through which a process gains
access to a network or bus.
quad pak module
An Opto 22 I/O module that features four points of discrete I/O in one package.
