The new broadband input/exit modules announced by Rockwell Automation for its range of programmable automation controllers (PAC) ControlLogix improve response times for high-speed sequential control applications.
Used in conjunction with the PAC ControlLogix 5570 range of controllers, Allen-Bradley's E/S 24 Vcc ControlLogix modules can significantly improve overall system response time (SRT) through new hardware technology and peer-to-peer communication capabilities that significantly reduce the time it takes for modules to communicate with the controller. Knowing that the system response time corresponds to the input module response time, controller processing and output module response time, reducing the latency of the I/S allows the machines to operate at higher speeds and produce more parts.
To deliver even faster performance, the new I/S modules also work in peer-to-peer mode by creating connections inside the chassis that allow them to communicate directly with each other without going through the controller. The controller is then discharged from processing and controlling the I/S modules, which helps improve the reliability of program delivery and throughput. In peer-to-peer mode, the response time from entry to exit can be less than 100 microseconds (? S). Peer-to-peer mode is ideal for applications that have fast detection-activation sequences, such as high-speed parts rejection.
"Manufacturers need to build faster machines for manufacturers looking to increase productivity and throughput," says Vincent Laulanet, Head of Automation and Software at Rockwell AutomationFrance. "PAC controllers are faster, but a controller's processing capacity is not the only factor affecting throughput. Designed for end-users and machine manufacturers running high-speed sequential control applications, our new I/S module can increase machine operating speed. The result is higher production of parts per post for the customer. »
The E/S 24 Vcc ControlLogix modules are available now and can be used with the PAC ControlLogix 5570 controller or any other Rockwell Automation programmable controller.
