SLC 500 Family of Processors
This course focuses on understanding PLCs; how they work,
terminology, and the hardware and software elements that make up a
programmable logic controller. Students will learn to use various
slot addressing techniques; how to understand program and data
table file organization, number systems and processor information
flow; and how basic relay type instructions, timers and counters,
& data manipulation instructions can be used to achieve PLC
This class is 80% Hands-On use of Allen Bradley MicroLogix 1400
Over 80 hands on lab projects are available and can be done based
on skill level. Each lab project is progressive to another.
We use custom training equipment made to be just like the
equipment on the floor. One work station for 2 students. Maximum
of 10 students per class.
