Abstract

PURPOSE:To prevent the life of a backup memory device from being shortened, by inhibiting the reload of a program for a prescribed time after start of the program, eve when the program is not being exected normally. CONSTITUTION:When a program stored in a random access memory 8 is partially broken down due to short break, etc. of a commerical electric power supply, execution of a program for replacement by a CPU5 is stopped substantially. In this state, a clear signal N having a constant period does not come into a counting circuit 11 from an input/output port 16, and a signal J outputted from the counting circuit 11 is varied to an H level. At this time, a signal K from an AND circuit 13 becomes an H level, and a signal B2 is generated from a pulse generating circuit 3. This signal B2 is supplied to a reset terminal R of a central control device 5, and reload of a program is executed. In this case, if an element itself in the memory 8 has been broken down, operation of a program is stopped before a prescribed time elapses, and a latching circuit 12 is not set.
