Claims

[Scope of utility model registration request]

a microcomputer, a display control unit that controls a display, a keyboard control unit that controls a keyboard that includes keys for inputting a ladder program;
Controls a character memory and a user program area for temporarily storing data input from the keyboard, the microcomputer, the display control section, and the keyboard control section, and processes according to the contents input from the keyboard. In a programming device for a programmable controller (hereinafter referred to as PC), which consists of different system programs, when creating a ladder program for the PC, there is a state in which only input of ladder symbols is accepted in order to connect only the connections in the ladder diagram, and a state in which only the input of ladder symbols is accepted in order to connect only the connections in the ladder diagram. A PC programming device characterized in that the software is provided with a ladder symbol and device data division input mode so as to divide the software into two states according to symbols, one in which only device data is accepted.
