In-Rack PC with OPC Server for ControlLogix

PC56-OPC

Limited Availability: Product with low inventory remaining. More Info

The PC56 with OPC Server allows you to access data from a ControlLogix PLC directly across the backplane, and connect to an OPC Client.

The PC56-OPC is an industrial PC for the ControlLogix platform that provides high speed communication with both local and remote ControlLogix processors. The PC56-OPC allows users to communicate with ControlLogix processors in an efficient, distributed, and cost-effective fashion.

Features and Benefits

The PC56-OPC allows you to access tag data from the ControlLogix Controller to a DAS Engine located on the PC56-OPC.

  • Improved reliability and performance: No middleware between client software and ControlLogix hardware
  • Easy Hardware Redundancy: Using two PC56-OPC, and then simply specifying two IP addresses for a very fast switching mechanism to support Redundancy.
  • Communicates with the ControlLogix controller directly through the ControlBus backplane, which simplifies installation and improves performance.
  • No modifications to the ControlLogix controller program are necessary.
  • Supports multiple ControlLogix controllers.
  • Supports both local (same rack as PC56-OPC) and remote (via 1756-ENET or 1756-CNET modules) controllers.
  • Easy-to-use configuration tools. Tag scan rates can be individually configured for optimal performance.

Application

The PC56-OPC allows you to access data from the ControlLogix Controller to an OPC Server located on the PC56-OPC. Multiple ControlLogix controllers may be accessed, either in the local rack or in remote racks connected via Ethernet or ControlNet.

Specifications

  • Communicates directly with the ControlLogix processor across the backplane for the most reliable data access·
  • Plug and Play. Can be added to new or existing ControlLogix PLCs without changing the control application
