可程式逻辑控制器;PROGRAMMABLE LOGIC CONTROLLER

摘要

本发明之可程式逻辑控制器，系具有：错误检测部(36)，用以检测错误；资料记忆体(304)，用以记忆依错误之种类显示错误检测部(36)是否已检测出错误的错误产生资讯；错误自动解除处理部(35)，就有关错误检测部(36)所检测出的各错误，判定错误要因是否已消除，当错误要因消除时，进行包括将错误产生资讯变更为错误未产生之处理的错误解除处理；及错误自动解除可否判定部(37)，参照错误自动解除可否设定(332)，在错误检测部(36)检测出错误时，根据错误解除可否设定(332)，判定是否为让错误自动解除处理部(35)解除的错误；其中，错误自动解除处理部(35)系就有关错误自动解除可否判定部(37)判定为是让错误自动解除处理部(35)解除的错误的错误，进行错误解除处理。; a data memory (304) for memorizing an error generation information indicating whether the error detector (36) has detected an error for each type of errors; an error automatic elimination device (35) for determining whether the cause of the error has been cleared with respect to various errors detected by the error detector (36), and performing an error-eliminating processing, which includes a processing of changing the error generation information into error ungeneration when the cause of error is cleared; and an error automatic elimination determining device (37) for determining, when the error detector (36) detects an error, whether the error is the error which can be eliminated by the error automatic elimination device (35) based on an error automatic elimination determining setting (332); wherein the error automatic elimination device (35) performs the error-elimination processing with respect to the error that is determined by the error automatic elimination determining device (37) as the error which can be eliminated by the error automatic elimination device (35).
