<P>PROBLEM TO BE SOLVED: To provide a program renewing method for an elevator capable of shortening program rewriting time and managing program versions all together. <P>SOLUTION: An elevator control panel 1 has a rewrite center 5 for transmitting a new program, a remote-monitor device 4, a RAM 41 for receiving the new program through the remote-monitor device 4, a control panel computing section 14 and an EEP-ROM 13. The control panel, in the case wherein the received new program is normal, forwards the new program from the RAM 11 to a new program region inside the EEP-ROM 13, and in the case wherein the new program received in an EEP-ROM new program region 132 is normal and a rewrite mode transfer condition is satisfied, forwards an EEP-ROM execution region 131 to an EEP-ROM back-up region, and in the case wherein the back-up is normal, copies the EEP-ROM new program region 132 in the EEP-ROM execution region 131, and in the case wherein the copy is normal, replies the remote-monitor device 4 that rewrite is succeeded, and the remote-monitor device 4 informs the rewrite center 5 that rewrite is succeeded. <P>COPYRIGHT: (C)2009,JPO&INPIT |
