PURPOSE:To attain direct programming from a time chart, by using a CRT, preparing two display screens, inputting information in the procedure writing the time chart and completing the program of a sequence circuit. CONSTITUTION:The two kinds of display screens are prepared for the CRT. The 1st display screen is divided into three areas (a)-(c). An output address to be controlled is described on the (a). An ON-OFF control pattern corresponding to the output is written in the (b). A circuit number to input the interlock condition is inputted to the (c). The interlock circuit corresponding to the interlock circuit number is programmed on the 2nd screen. Then, the data inputted to the (a)-(c) are stored in an output table 1, an output pattern 2, and a step transfer table 3 respectively. The interlock circuit data is stored in an interlock condition table 4. The sequence control is performed based on the stored information. |
