Function Libraries Thread and PLC_PRG ∗ : The way the thread is processed compared with the freewheeling control cycle not only depends on the thread's parameters but also on the execution time of both the thread and PLC_PRG. TSLICE< thread execution time start PLC_PRG time slice PLC_PRG TSLICE TSLICE ... thread ... PLC_PRG time slice PLC_PRG ... thread End of PLC_PRG process image communication time slice PLC_PRG In this case, PLC_PRG runs through a time slice of a size of 800µs, i.e. at the end of this time processing it is interrupted. This is when the thread starts running for a time 'TSLICE'. Task management then returns control to PLC_PRG etc., etc. Once the last PLC_PRG command has been executed the actions linked to PLC_PRG, i.e. refreshing the process chart and communication, will be taken only to resume the cycle with the first command again. In our example, the threaded program is not completed within a single TSLICE. If the program is shorter or TSLICE is longer, the thread could also run more than once within one TSLICE. In any case, thread processing is stopped when it has run the specified number of times. ∗ We are cutting out the influences that other processes may have. TSLICE 74 E 700 GB thread time
4.4.2 Installing / Uninstalling a Timer Task Function Libraries A timer task is an executable unit within a program run with several other processes being allowed to run at the same time but without a time slice being allocated to the timer task. In other words, this kind of timer task is run exactly when it is requested to by a timer interrupt. Timer task properties: The program identified by its index is marked as a separate process by the operating system and runs at defined intervals, interrupting the process that is currently running. The timer task is run once, then terminated and the interrupted process is resumed. Parameter Type Value Explanation NPOU_IDparam WORD module index TTIME WORD Timer task usage: 1.. 65535 time interval, in 1ms (1ms..65,535s) 0 not allowed! A timer task is beneficial wherever everything depends on a high accuracy of repetition in time. Timer tasks work just like timer modules in KUBES controllers. The watchdog can be enabled. The programmer must make sure that the timer task's runtime never exceeds the time set as "TTIME". 75
