ABSTRACT:
A method for operating automation control equipment applications ensures uninterrupted execution of a control application, at least during specific time periods, but such that the control application does not have the access privileges of a device driver. The operating system is configured for preventing calling of the processor commands from the control application, the processor communicating with the controlled automation equipment via a programmable bus interface. An embodiment of the method comprises the steps of performing read and write access of the control application to the bus interface directly and without routines of the operating system or device driver, and suspending processing of hardware interrupt calls of the processor during a preselected time period. Read and write access of the control application to the bus interface is thus carried out directly, rather than via routines of the operating system, and hardware interrupt calls of the processor are not processed during specific time periods.
