Abstract: A method for operating cycle-oriented control software for controlling processes, wherein the software executes within a runtime environment on a computer system and uses two independent time bases: a first time base derived from a hardware timer, and a second time base provided by a another timer is transmitted via a network communication, and the second time base is provided via telegrams with time stamps, where a receive routine assigns time stamps to a receipt time and stores them in a buffer, an evaluation routine recognizes and compensates interrupts that disrupt the safe time base, the past values of the first time base are stored in a cyclical buffer that an interrupt handler periodically updates, the evaluation routine checks the time differences between the telegrams and corrects the second time base if required, such that reliable and safe time measurement are ensured, even in the event of system management interrupts.

Abstract: Method for operating a segment of cycle-oriented control software, wherein to test, in a virtual control system, execution of a cold start mechanism, on a start-up of a runtime environment, a random number is generated, stored in a storage region and added to the storage region upon every further request for a safety time, where at the start of a new cycle, the deviation of the time differences is calculated and, in each cycle, the storage region is accessed and before calculation of the time differences, the random number is re-subtracted from the safety time, when a new start-up of the runtime environment has occurred, this is diagnosable via the tolerance being exceeded, because the second time difference now has an offset that results from the safety time with a new random number of the current cycle and the safety time with the old random number of the previous cycle.

Abstract: A method for monitoring a communication connection between first and second subscribers, wherein a first processing program with a first cycle time is executed cyclically in the first subscriber, where in order to monitor the communication connection a first diagnostic unit with a first time counter is operated in the first subscriber, such that an arrival of a first telegram from the second subscriber starts the first time counter, an arrival of a second telegram from the second subscriber is monitored within a predefinable first monitoring time with the help of the first time counter, wherein a residual period is formed in the first diagnostic unit from the difference between the first monitoring time and the first time counter, and where a check is made to see whether the residual period is less than or equal to the first cycle time, and if so a monitoring signal is generated.
