We are able to offer very competitive prices for Allen Bradley full range of products, including PLC, PAC, Motion Controllers and etc. Programmable Controllers Solutions that Set the Industry Standard Allen-Bradley control solutions set the standard---from the Programmable Logic Controller (PLC) invented nearly 30 years ago to the more recent technology embodied in the rugged, scalable, highly-functional Programmable Automation Controller (PAC) . The reason? You move forward with our control solutions while protecting the control investment you made in the past. We offer multiple types of controllers to fit your specific needs: Programmable Automation Controllers Merge PC-based and PLC architecture Provide multidiscipline automation (i. E. , process, discrete, motion, drive and batch) within a single hardware and software platform Provide scalability and application portability within an open, modular architecture Programmable Logic Controllers Implement specific functions such as: I / O control Logic Timing Communication Report generation Data file manipulation Arithmetic Counting 1756 ControlLogix Controllers The ControlLogix controller provides a scalable controller solution that is capable of addressing a large amount of I/ O points. The ControlLogix controller can be placed into any slot of a ControlLogix I/ O chassis and multiple controllers can be installed in the same chassis. Multiple controllers in the same chassis communicate with each other over the backplane (just as controllers can communicate over networks) but operate independently. ControlLogix controllers can monitor and control I/ O across the ControlLogix backplane, as well as over I/ O links. Controllogix controllers can communicate with computers or other processors across RS-232-C (DF1 / DH-485 protocol) , DeviceNet, DH + , ControlNet, and EtherNet / IP networks. To provide communication for a ControlLogix controller, install the appropriate communication interface module into the chassis. The multitasking operating system supports 32 configurable tasks that can be prioritized. One task can be continuous. The others must be periodic or event tasks. Each task can have as many as 100 programs, each with its own local data and logic, all
