Rockwell Automation introduced its Allen-Bradley Micro870 PLC, a new flagship of the Micro800 family, designed to be used in place of multiple micro PLCs. Machine designers can use this new micro PLC to help optimize the control architecture in large standalone machines or systems. The new Allen-Bradley Micro870 PLC can support smart micro applications that require up to 304 I/O points, 280 KB of memory and 20,000 program instructions.
The Micro870 PLC uses a more flexible design concept that provides users up to three plug-ins and eight expansion I/O modules. This capability allows users to help to customize or expand the controller to meet the unique requirements of additional machine types.
The controller’s 280 KB memory capacity supports modular programming and the use of user-defined function blocks to help reduce design time. Additionally, machine builders can use this memory capacity to help maintain a single program for all machine models that use the Micro870 PLC.
The controller communicates via EtherNet/IP and includes multiple embedded communications options including a USB programming port, a non-isolated serial port, and an Ethernet port. It can also support up to two axes of motion.
The new Connected Components Workbench software version 11 provides a single design environment for programming the Micro870 PLC. The software can also be used to configure Allen-Bradley PanelView 800 graphic terminals, PowerFlex AC drives, Kinetix component servo drives, electronic overload relays, light curtains and configurable safety relays. This feature can help to save time and costs compared with using separate programming tools for each device in a system.
A new conversion tool in version 11 helps to make it easier for MicroLogix customers to upgrade to the Micro800 controller family. In addition, version 11 allows Encompass members of the PartnerNetwork program to help ease configuration of complementary third-party products via graphical configuration profiles. These profiles support the Micro800 plug-ins as well as expansion I/O to help make the configuration process faster and more accurate.
