This new approach allows extremely time-critical subprocesses to be managed using standard hardware - all within the requirements of IEC 61131 - while reducing the load on the controller and optimizing performance to match demands. The result is an increase in performance without added costs. The fastest response times achieved in the field, from receiving the input signal to sending the output signal, have seldom been under 100 µs - until now. Programs created in the function block editor are executed directly on I/O modules, eliminating internal data transmission and allowing response times to be reduced to as little as 1 µs. The technology takes advantage of the company's Automation Studio 4 development environment's ability to allocate software modules to distributed hardware and utilize the surplus capacity of logic components in the modules. This allows function block libraries to be stored there through the use of dynamic updates. These libraries can then be executed locally on the I/O module like the command set for a microcontroller, allowing time-critical subprocesses to be implemented using standard hardware and eliminating the need for specialized modules - all while reducing the load on both the network and controller.
