PURPOSE:To attain an automatic restart even when an arithmetic means is stopped by a transient noise by transmitting a rerise signal within a fixed time during which the stop time of an arithmetic processing action is allowed. CONSTITUTION:A collation means b collates the coincident state of the arithmetic results of arithmetic means a1 and a2 with each other and stops the arithmetic processing actions of both means a1 and a2 when no coincidence is obtained between both arithmetic results. A restart deciding means e calculates the stop time of the arithmetic processing action from the difference between the coincident time data stored in the memory means d and d' and the coincident preset times obtained from the timepiece means c and c'. Then the means e restarts the operations of both means a1 and a2 when the stop time is kept within a prescribed time. Thus the rerise is automatically secured for a controller when the discordance of collation is produced by a transient noise, etc., and the controller has a down. |
