Extension Article: Introduction to Control
In the next few issues of the
Extension, we are going to step
back quite a bit from our in-depth
discussion of technology in
order to explain to laymen the
industry we serve. We hope that
people in your organization
will benefit from some basic
knowledge of our industry.
Extension Article: Implementation of a Control Project
In the last Extension article entitled, "Introduction to
Control," we introduced some basic control systems
concepts. We discussed the topic of measurement and
the role of input and output transducers within either
an open or closed-loop control system. Now we will
examine how control systems are actually implemented
in industry.
Extension Article: Introduction to Industrial Networking
In the last two articles we discussed some basic control
system concepts. The systems mentioned were centralized
control systems in that a single controller had directly attached
to it input and output devices. This is the most common
implementation of a control system found in the industry.
The centralized controller would act upon the state of the
various input devices and setpoints by manipulating outputs
to achieve the desired result.
