ABSTRACT:
In an elevator control apparatus, a control apparatus main body includes a program storage portion for storing a program concerning operational control of an elevator and a processing portion for performing a plurality of calculation processings based on the program. Further, the control apparatus main body writes pieces of processed information corresponding to the calculation processings, respectively, into the RAM when the calculation processings are performed, and monitors whether or not a sequence of performance of the calculation processings is normal by reference to a pattern of the pieces of the processed information written into the RAM.
