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.
