9. Data Processing Design Examples Control Program: M10 M11 M11 Program Description: z When M10 = ON, ENCO instruction will be executed. Any product entering main production line will be encoded with its sub-production line number, and the result will be saved in D0. By monitoring the value in D0, the operator can identify the type of the entering product. z When M11 = ON, DECO instruction will be executed to decode the specified value in D10 into Y0~Y7 so as to disable the corresponding sub-production line. For example, when D10 = K5, the decoding result will be Y5 = ON. In this case, No. 5 sub-production line will be disabled.
When M11 = OFF, ZRST instruction will be executed and Y0~Y7 will be OFF. All sub-production lines will operate normally. z If the set value in D10 is out of the range between K0~K7, HFFFF will be written in D10, so as to prevent the production line interruption due to other written value in D10.
