PLC:
Beckhoff
A
programmable microprocessor-based device that is
used in discrete manufacturing to control assembly
lines and machinery on the shop floor as well as
many other types of mechanical, electrical and electronic
equipment in a plant. Typically RISC based and programmed
in an IEC 61131 programming language, a PLC is designed
for real time use in rugged, industrial environments.
Connected to sensors and actuators, PLCs are categorized
by the number and type of I/O ports they provide
and by their I/O scan rate.
