Abstract: The present invention is concerned with a stability supervision or monitoring of a communication system of an industrial Process Control (PC) system, by measuring the communication load and comparing the latter to a previously established base load. The measured communication load is represented by a plurality of updated, or present, echo delay measurements for communication paths between a supervising Intelligent Electronic Device IED and end-IEDs of the communication system. The echo delays are established by sending, by the supervising IED, echo poll messages to the end-IEDs, and by receiving an echo from the end-IEDs. If a difference between measured and baseline echo delays exceeds a predetermined threshold, an overload status is signalled to an operator. Hence, a refined dynamic communication network status, beyond a mere binary good/bad indication, is obtained without additional hardware and excessive dedicated communication load.

Abstract translation: 本发明涉及对工业过程控制（PC）系统的通信系统的稳定性监视或监视，通过测量通信负载并将其与先前建立的基本负载进行比较。 所测量的通信负载由对监控智能电子设备IED和通信系统的终端IED之间的通信路径的多个更新或存在的回波延迟测量值表示。 回波延迟通过发送IED监听回波轮询消息到终端IED，并通过接收来自终端IED的回声来建立。 如果测量和基线回波延迟之间的差异超过预定阈值，则向操作员发信号通知过载状态。 因此，在没有额外的硬件和过多的专用通信负载的情况下，获得超出仅二进制好/坏指示的精细动态通信网络状态。
