1. Basic Program Design Examples Program Description: z When X0 goes from OFF to ON, the auto control process will be executed once, whereas when X1 goes from OFF to ON, the manual control process will be executed. In the manual control, the clipping and releasing actions require pressing the corresponding button for one time. However, the button Transfer should be pressed for 2 sec during the moving process till the product is moved to Conveyor B. z X0 and X1 are interlocked. When the auto control process is executed, the robotic arm will perform the following actions:
first “clipping”, then “transferring” (for 2 sec.), and “releasing.” When the manual control process is executed, the controlling actions will be performed by 3 corresponding buttons: clipping product by turning on Y0, transferring product by pressing Y1 and releasing product by turning off Y0.
