ABSTRACT:
A programming device for preparing a sequence control program to be executed by a programmable sequence controller comprises designation means for designating input and output (I/O) elements specified in the sequence control program which are to be fixed to ON or OFF states regardless of the actual ON or OFF states of the designated I/O elements, fixed I/O element converting means for converting the address of each of the I/O elements designated to be fixed by the designation means into either a memory storing address ON-state or another memory address storing OFF-state so as thereby to prepare a modified sequence control program, and loading means for loading the modified sequence control program to the programmable sequence controller being connected to the programming device.
