The new high-speed I/O modules announced by Rockwell Automation for its ControlLogix range of Programmable Automation Controllers (PACs) improve response times for high-speed sequential control applications.
Used in conjunction with the ControlLogix 5570 range of PAC controllers, Allen-Bradley's ControlLogix 24 Vdc I/O modules can dramatically improve overall system response time (SRT), thanks to new hardware technology and peer-to-peer communication capabilities that significantly reduce the time required for modules to communicate with the controller. Given that system response time corresponds to the time taken for the input module to respond, for the controller to process and for the output module to respond, reducing I/O latency enables machines to operate at higher speeds and produce more parts.
For even faster performance, the new I/O modules also operate in peer-to-peer mode, creating connections inside the chassis that enable them to communicate directly with each other without passing through the controller. This relieves the controller of the task of processing and controlling the I/O modules, helping to improve program execution reliability and throughput. In peer-to-peer mode, the response time from input to output can be less than 100 microseconds (?S). Peer-to-peer mode is ideal for applications involving fast detection-activation sequences, such as high-speed part rejection.
" Designers need to build faster machines for manufacturers looking to increase productivity and throughput "explains Vincent Laulanet, Automation and Software Manager at Rockwell AutomationFrance. " PAC controllers may be faster, but a controller's processing capacity isn't the only factor affecting throughput. Designed for end-users and machine builders running high-speed sequential control applications, our new I/O module can increase machine operating speed. The result for the customer is higher production of parts per shift. "
ControlLogix 24 Vdc I/O modules are available now for use with the ControlLogix 5570 PAC controller or any other Rockwell Automation programmable controller.
