PURPOSE:To enable check the abnormity or failure in a device without stopping the device and to improve the reliability of the device and processing efficiency, by providing a plurality of systems consisting of EPROM socket and personal module. CONSTITUTION:Data of an RAM8 are written in EPROMs inserted to EPROM sockets 6, 6a via personal modules 5, 5a through the control of a CPU3 and a control section 11 according to a program of an ROM7 through the set of a display operation panel 2. When the setting of a transfer mode is made on the panel 2, the data from each EPROM is fed to a designated address region of the RAM8 under the control of the CPU3 and the control section 11. Failure and abnormity of each module system is easily detected, by confirming the coincidence of data in each address region of the RAM8. |
