PURPOSE:To change quickly the input/output data, by setting and storing an optional forcible operation pattern using three values, i.e., forcible ON, forcible OFF and non-forcible mode in terms of the input/output data. CONSTITUTION:For a programmable controller shown in the diagram, the user programs are successively read out of a memory 5 to undergo an arithmetic process with the input/output data within an input/output memory 7 or with the input data set at an input/output device 6. This data is delivered to the device 6 via the memory 7 to give a sequence control to external devices. A forcible operation switch is provided to a keyboard 8A of a program console 8 and changes the data of the memory 7 in accordance with a forcible operation pattern of the input/output data which is previously set and registered. The memory 5 stores plural forcible operation patterns in three values, i.e., forcible ON, forcible OFF and non-forcible mode respectively in terms of all input/output data. |
