“Tasks” section
This section allows to display in a graph the PLC tasks execution sequence even included optional user events, inserted by the GFB_SYS(615).The system can collect up to 100000 events, inside a circular buffer. With buffer full older events will be discarded.Total samples time depends on PLC execution time. For example, with FAST = 5 msec, NORMAL = 40 msec, SLOW = 80 msec, the buffer can hold nearly 70 seconds.Decreasing the PLC time (higher execution frequency) the total sample time decreases. Also adding custom events the total time will decrease but also can increase if the PLC doesn’t use NORMAL or SLOW tasks.This is an output example from the tool:
For easily reading, traces “READIO” (inputs reading) and “WRITEIO” (outputs writing) are drawn one over the each other.
