Abstract
PURPOSE:To facilitate the operation of making a new sequence (SQ) by representing each program (PG) for sequence control by logic symbols (LGS) and by displaying the program on a CRT by connecting respective LGSs. CONSTITUTION:Inputs X001-X006 to an SQ controller 3 are fetched in an input circuit 31 and processed by a control circuit 34 according to a sequence program in a main memory 33, and the results are stored in an accumulator 35 and outputted to an output relay Y001 via an output circuit 32. Through operation on the keyboard 27 of an SQ display device 2, the PG from the memory 33 is fetched in a buffer memory 24 and, under the control of a control circut 25, is converted into a PG consisting of LGSs by a conversion PG stored in an ROM27 to be stored in a refresh memory 22. According to the PG in the memory 22, a CRT control circuit 21 displays a signal from a symbol generator 23 on a CRT1 as one logical display unit. When an operator indicates that this display unit is used as one element of the SQ, LGSs of each displayed SQ are displayed simultaneously on the same screen by being connected together.
