PURPOSE:To read and record automatically information at the time of occurrence of an error which is stored when an error is detected, by storing detailed information at the error occurrence time each time the error occurs in the operation controller side. CONSTITUTION:If an error occurs in a stored program-system operation controller (PC) 2, a CPU 2a discriminates a factor of error occurrence and sets a flag (EF) 2d corresponding to the factor and records detailed information at this time of occurrence of an error in an error information recording part (EIR) 2e. Meanwhile, an error detection processing part (EK) 1e on the side of a programming device (PP) 1 reads out periodically contents of the EF 2d; and if the flag EF 2d is set, the EK 1e discriminates the occurrence of an error in the PC2 and starts an error information reading part (ER) 1f to read contents recorded in the EIR 2e. After reading, contents are edited and are printed by a printer 3. |
