DVP-ES3 Series Programming Manual points on the module to be refreshed. Otherwise, the instruction cannot read the correct states of the inputs. See Additional remarks, below. 7. In general, the conditional contact used in the instruction is SM400: the flag is always ON when CPU runs. 8. The value in n must be between 2–8. Example 1 1. When M0 is ON, the MTR instruction is executed. The instruction reads the states of the two rows of switches in order, and stores them in the internal relays M10–M17 and M20–M27 respectively. 2. The diagram below is the external wiring diagram of the 2-by-8 matrix input circuit for X0–X7 and Y0–Y7.
The corresponding internal relays of the 16 switches are M10–M17 and M20–M27. _6 M20 M21 M22 M23 M24 M25 M26 M27 Y1 Y0 X1 X2 X3 X4 X5 X6 X7 3. The instruction connects eight input devices starting from M0 to the two output devices starting from M1 to form the two rows of switches. The matrix scan reads the states of the two rows of switches, and stores the states in the devices starting from M10 (specified by D 2 ). That is, it stores the states of the first row of switches in M10–M17, and stores the states of the second row of switches in M20–M27. 6-190 M10 M11 M12 M13 M14 M15 M16 X0 X1 X2 X3 X4 X5 X6 X7
