CODESYS HMIs

Select Maple HMIs have a sleek hardware platform that runs both an HMI application created with EasyBuilder Pro and PLC logic programmed with CODESYS; each on its own dedicated processor. Unlike the typical multicore set up, where the operating system scheduler is responsible for allocating tasks to each processor, these HMIs have a hard separation between cores. One core is dedicated to the HMI application, the other to executing PLC logic of the CODESYS project. This ensures taxing graphics processing operations will not interfere with deterministic real time control tasks executing on the other processor. Even in the unlikely event that the HMI applications crashes completely, the PLC Logic will continue to execute.
