Symphony Plus as IEC104 master DP command(46) not available when running for sometime
The customer report that when running for sometime the faceplate shows * *64 and command cannot be sent out. However, the status of digital and analog is all right. When * *64 is showed, the tag quality is OL. And I checked the popup of DP commnad, the * *64 is using value of DB_INFO_ALMST and I cannot find this item in Database view, the similar one is DB_ALARM_CODE and the value is 24. Can someone explain what has happened?
