The Micro800 Control Systems by Rockwell Automation provide a cost effective solution for small to medium automation systems. The controllers within this family are typically used on stand alone machines or small process applications. The family offers five distinct controller types that are further customizable through add-on modules: Micro810, Micro820, Micro830, Micro850 and Micro870.Micro800 Programmable Logic Controllers Getting StartedUnlike the other Rockwell Automation controllers, this line of PLCs is programmed through a dedicated software: Connected Components Workbench. From within this tool, the programmer can flash the firmware, load the program and monitor the state of the controller. Furthermore, Connected Components Workbench (CCW) is often used to program other non-PLC Rockwell Automation devices such as Variable Frequency Drives (VFDs) and certain Safety Relays.
Industrial Relays have been used in Automation for decades. These fundamental building blocks of electrical circuits allowed the first automated systems to function without the need of modern PLCs and computers. Although you won’t find any relay based logic circuitry today, they still play an important role in modern control systems.

Many of those who start with PLC programming are faced with the challenge of deciphering code written by someone else. In fact, most PLC programming jobs will require you to work with existing code rather than write it from scratch. This task creates a challenge for novice PLC programmers as the interface in RSLogix 500 as well as RSLogix 5000 is unlike any other. Therefore, it’s easy to become frustrated trying to figure out where a certain tag is being used, how it ties into the logic and why it’s being used in certain places.
