Recently, Rockwell Automation introduced a new small programmable logic controller that can be used by machine designers to optimize the control architecture of large, stand-alone machines or systems. The new Allen-Bradley Micro870 PLC supports up to 304 I/Os. Points, small smart applications with 280KB of memory and 20,000 program instructions.
'In the design of automation projects, designers often use multiple types of PLCs,' said Yeow Keng Teh, Rockwell Automation's product manager for small controllers. 'This requires inventory management of multiple PLC types. , And maintenance of multiple sets of programs. Now, designers can use Micro870 PLC, according to their own application needs flexible scaling controller. This helps to achieve the simplification of inventory management, especially for designers who want to design a variety of machines . '
With its flexible design concept, the Micro870 PLC supports up to three functional plug-ins and eight expansion I/O modules. With this, the designer can easily customize or expand the controller for the unique requirements of various types of machines.
The controller's memory capacity is 280KB, supports modular programming, and supports the use of user-defined function blocks, which helps to reduce design time. In addition, with the memory capacity advantage, the machine manufacturer can also use the machine models for all Micro870 PLCs. Unified maintenance of a program.
The controller communicates via EtherNet/IP and includes a variety of embedded communication options, such as USB programming ports, non-isolated serial ports, and Ethernet ports, and can support up to two axes of motion.
The new 11th Edition Connected Components Workbench software can be used to complete the programming of the Micro870 PLC in a one-stop shop. The software can also be used for Allen-Bradley PanelView 800 graphics terminals, PowerFlex AC drives, Kinetix component-level servo drives, electronic Overload relays, light curtains, and configurable safety relays are configured. This feature helps engineers save time and costs compared to traditional methods of using different programming tools for each device in the system.
The 11th edition adds a new conversion tool that allows MicroLogix customers to easily upgrade to the Micro800 controller family. In addition, the 11th edition also provides graphical configuration files, allowing Encompass members of the Partner Alliance program to easily complement the Three-party products are configured. These configuration files support both the Micro800 functional plug-in and the extended I/O, which helps to complete the configuration work more quickly and accurately.
