8. Rotation and Shift Design Examples same time, CMP instructions will be executed to confirm product A at position 2 (D101), product B at position 4 (D103) and product C at position 6 (D105). After each CMP instruction, RST instruction will be executed to clear D0. z If product A , B or C is confirmed at position 2, 4 or 6, the corresponding M11, M21 or M31 will be ON to enable electromagnetic valve A, B or C to push the products in the containers. z When the falling of each product is detected by sensors, X3, X4 or X5 will be ON to reset electromagnetic valve A, B or C. z When RESET is pressed, X7 = ON to execute ZRST instruction.
The value in D100~D105 will be 0, which means all data memory will be cleared. DVP-PLC Application Examples 8-7
