Abstract
PURPOSE:To perform write, check, etc., of a program efficiently by generating alarm in case of an erroneous key operation in a stepping sequence controller where the program is inputted by key operations. CONSTITUTION:In write of a program for external load control, a CPU reads a program for write of internal control from a ROM and scans switching states of external input terminals IN1-INn, console switch CS, switch S2, etc., and key group 1 and discriminates program write or execution on a basis of the state of an internal input circuit. When the input state becomes program write, instructions set by key group 1 are written into memory M successively. The CPU displays contents of program steps on display parts 2, 3, 51-54. In case of an erroneous operation, memory M and display parts are not changed from states before the erroneous operation through a driving signal is outputted from the CPU to buzzer BZ. Consequently, the erroneous operation can be found to perform a correct operation, and write, etc., of the program efficiently.
