DVP-ES3 Series Programming Manual 8. The instructions DHSCS, DHSCR, DHSCY and DHSZ cannot be used in the ST programming language, interrupt tasks or function block which is called only once. Example 1 When M0 is ON, the DHSCS instruction is executed. When the current value of HC200 changes from 99 to 100 or from 101 to 100, Y10 is ON, which outputs to the external output terminal Y10 in real time, and remains ON. Example 2 The Y output of DHSCS instruction is different from the general Y output. 1. When M0 is ON, the DHSCS instruction is executed.
When the current value of HC200 changes from 99 to 100 or _6 from 101 to 100, Y10 outputs its state to the external output terminal immediately, and is not affected by the program scan time. 2. When the current value of HC200 changes from 99 to100, the contact of HC200 is ON immediately. When SET Y0.11 is executed, Y11 is still affected by the scan time, and outputs its state only after END is passed. 6-284
