各位好
目前我使用kapware搭配labview的DSC module的Data Socket應用OPC技術來抓取我所需要的值,並寫入MS SQL之中
在I/O server之中建立的tag多達上萬點,在distributed system manager中常各tag常發生disconnect的情形
,觀看人機介面上的indicator也多數呈現無值的狀態
再參考以下文章之後
http://forums.ni.com/t5/LabVIEW/OPC-Client-with-Yokogawa-Centum-Server/td-p/2387278
文中說I/o server的tag只能建立500點,超過就會發生連結斷裂的情形
請問是否有方法可以達到萬點同時抓值並連線穩定?

從下面這篇看起來沒有500點的限制,只說IO點過多的時候會變慢。

另外,對於點數極多時,請參考以下教學做為設計準則。
