You may use "SFC1" (READ_CLK) can be used. Simply compare time & fulfill your logic requirement. OB10-17 can be triggered on particular time & it will be called only once. For more info attaching help file from "Step-7 offline help". I hope, it might needful to you. Attachments7.pdf (404 Downloads) |
