Bug #1784

SHL15 dac处理服务器analog实时库接收电力AI溢出坏值-4194304后,当ehrawdc采集到好值更新上来后,analog的对应值僵死-1.#IO不能更新好值(ehdc显示-1.#IND00,ananlog显示-1.#IO)

20211015上电科反应过SHL15正线 3个车站发现此种情况
20211108晚施工点调度再次上报此故障。
ai点号978开始一段数据analog显示-1.#IO,对应ehdc-ehrawdc显示数值正确
另,edhdc的AI 1003点显示-1.#IND00

问题复现了,pscadaAI设备给-4194304(0x00 00 c0 ff)坏值后,ehdc显示-1.#IND0、analog实时数据界面刷新显示-1.#IO,analog实时操作SQL查询结果显示-1.#J
pscadaAI设备给好值后,ehdc立马恢复刷新,但analog就僵在-1.#IO那里不再刷新了(我们dac服务器处理问题,需消缺)******

pscadaAI设备给(0x00 00 80 ff)坏值后,ehdc显示-1.#INF0、analog实时数据界面刷新显示-1.#IO,analog实时操作SQL查询结果显示-1.#J
pscadaAI设备给好值后,ehdc立马恢复刷新,但analog也能正常刷新,没问题

关于,400V分段功率因数 1003、1248点,pscada车站向现场信号屏也显示-NaN,我们ehdc显示-1.#IND0,抓包wireshark也显示-1.#IND0,没有问题,属于pscada设备厂家PLC数据传送问题。

修改104协议,对于溢出值采用剔除,作为坏值,不执行putayc()来处理
