Introduced in 1999, the ControlLogix series fromAllen-Bradley has been a workhorse for many years. The series is divided between the 5580 and5570 models, with significant differences in capabilities between the two. The Siemens equivalent, the S7-400 seriescontroller has been in service almost as long as the ControlLogix and consistsof four base models, the CPU 412-1, CPU 412-2, CPU 414-2, CPU 414-3, CPU 416-2,CPU416-3 and CPU 417-3. Both aredesigned for large industrial automation systems.
At the basic end of the spectrum are the Allen-BradleyMicroLogix and the Siemens S7-200. Theseare both used for smaller applications or standalone equipment that only needsbasic control and motion function. Thereare five base models in the Allen-Bradley MicroLogix family including the 1000,1100, 1200, 1400, 1500. Likewise, thereare five base models in the Siemens S7-200 family including the CPU 221, CPU222, CPU 224, CPU 224XP and CPU 226.

The Flexy supports different Rockwell models: SLC 50x, MicroLogix, PLC5, ControlLogix, CompactLogix, FlexLogix, ...
- [Narrator] There are different types of PLC controllers on the market from various manufacturers. Here are a couple of examples of the ones by Allen Bradley from Rockwell Automation. In general while the fundamental concepts of PLC programming are common to all manufacturers there are differences between them. For example, the controller size, memory organization, I/O addressing, instruction set and the applications that are used for which means that PLC programs are never perfectly interchangeable among the various models of PLCs. The two PLCs you see here are from Allen Bradley and Siemens and sometimes even within the same product line of a single manufacturer different models may not even be compatible. As for example Allen Bradley ControlLogix and MicroLogix. Allen Bradley controllers are generally classified into three categories depending on the controller group type and its associated software. The controller category is organized by the size of the controller and its application. The software comes in two types. RSLogix 500 and RSLogix 5,000. The first group is MicroLogix controllers. There are relatively small controllers used for low cost stand alone machines for small control systems. MicroLogix controllers use RSLogix 500 software. The second group is CompactLogix and SLC 500 controllers they are still considered small controllers used for medium sized applications and processes but they have more advanced capabilities to be used in manufacturing. CompactLogix controllers use RSLogix 5,000 software and SLC controllers use RSLogix 500 software. The third group is ControlLogix controllers. They are used for large control systems. In general they provide faster system performance for large processes compared to the other two controller groups. ControlLogix controllers use RSLogix 5,000 software.
Qualitrol International repairs all models of the popular Rockwell Allen-Bradley PanelView and PanelView Plus family of Human Machine Interfaces (HMI). Today, virtually every Allen-Bradley PLC system has one of the many models of the PanelView Operator Interface.
Lots of industries and standard bodies are now getting on this bandwagon. One of the first ones is the Oil and Gas association that is concerned with the devices and data descriptions for oil platforms. It will be interesting to see how all these efforts progress in the future and what things will look like for Industrial Automation when true data models start to get used on the factory floor.
The following information applies for Allen-Bradley PLCs for the purpose of setting up Implicit I/O Messaging via EtherNet/IP. The models included for this setup are (this setup applies only to these): 2ff7e9595c
