Rockwell Automation’s AB Micro850 and Micro870 PLC Systems Provide Connectivity, Design Efficiency

July 14, 2023
The Allen-Bradley Micro850 and Micro870 programmable logic controller (PLC) systems use Class 1 implicit messaging capability for connectivity and design efficiency.

Rockwell Automation expanded the capabilities of its Micro850 and Micro870 PLC systems to offer more connectivity, simple integration to PowerFlex 520 series and Kinetix 5100 drives via predefined tags, and easy programming to drives with the use of Connected Components Workbench software version 21 or later.

Key features of the Micro850 and Micro870 PLC systems include:

  • improved performance with increased I/O response and code execution time
  • increased protocol connectivity with additional DNP3 (Micro 870 only) and expanded DF1 communications support
  • easy recognition of new controller options with catalog numbers containing E, for Ethernet connectivity, after the controller series (e.g., 2080-L50E)
  • operates in -20…+65 °C (-4…+149 °F) temperatures
  • supports microSD card for program transfer, datalog and recipe management through plug-in module.

Minimize Programming and Troubleshooting Time

Allen-Bradley Micro850 and Micro870 controllers offer greater connectivity and design efficiency through the Class 1 implicit messaging capability with up to eight EtherNet/IP devices supported, according to the company. Other benefits include easy programming and simpler workflow through a familiar and intuitive design environment.

Connected Components Workbench software version 21 is the required minimum to support the Class 1 implicit messaging capability in the PLCs. Controller and software enhancements can help drive industrial operations productivity while lowering costs, according to Rockwell Automation.

Additionally, users can minimize programmatic efforts and troubleshooting time, which simplifies the development of standalone machines. Expanded smart capabilities allow automation projects to be developed and deployed faster, which can accelerate time to market and drive business growth.
