We have integrated Areva relays with our Data Concentrator on IEC 103 protocol. we are taking Areva relays protection signals on DCS via Data concentrator on IEC 104 protocol. I'm facing one problem is that whenever that protection gets operated then that signal updates in DCS as well as in Data Concentrator but when we Reset it in to relay or normlise the relay then its not updating in DCS as well as in Data Concentrator. The signal continuously remains high on DCS & shows that there is fault on relay even if I resetted in relay. Please suggest me that there is any solution for this in IEC 103 protocol???????

How to overcome from this problem ????
