March 29, 2018 — Rockwell Automation’s latest micro programmable logic controller (PLC) is designed to help optimize the control architecture in large standalone machines or systems. The 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 design concept that provides designers up to three plug-ins and eight expansion I/O modules. This capability allows them to customize or expand the controller to meet each machine type’s unique requirements.
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 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 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.
