ISPSoft User Manual The programs in the POUs are as follows. Suppose the four POUs of the program type are assigned to cyclic task (0). The arrangement of the POUs is shown below. The order in which these POUs are executed is Prog0 Prog1 Prog2 OUTPUT. The value in D0 in OUTPUT depends on the program in Prog2. When M0 is ON, the value in D0 in OUTPUT is 2. After the value in D0 is transferred to Y0, the value in Y0 will be 2. In other words, Y0.1 will be ON after a scan cycle is complete. The equivalent program is shown below. 5-14
