Glossary<br />
The National Electrical Manufacturers Association publishes standards for the<br />
performance of various classes of electrical enclosures. The NEMA standards cover<br />
corrosion resistance, ability to protect from rain and submersion, etc. For IEC<br />
member countries, the IEC 60529 standard classifies the ingress protection rating<br />
for enclosures.<br />
P<br />
The Programmable Logic Controller is the “brain” of an industrial manufacturing<br />
process. It automates a process, used instead of relay control <strong>system</strong>s. PLCs are<br />
computers suited to survive the harsh conditions of the industrial environment.<br />
Pulse Latch Input<br />
A Program Organization Unit includes a variable declaration in source code and the<br />
corresponding instruction set. POUs facilitate the modular reuse of software<br />
programs, <strong>functions</strong>, and function blocks. Once declared, POUs are available to one<br />
another. SoMachine programming requires the utilization of POUs.<br />
Pulse Train Outputs are used to control for instance stepper motors in open loop.<br />
