Hi every one ,
Good friday .
Our company ran a new production line last year .
and used VOITH paper machine ,
and they gave us a OPC solution software named "Data Bridge" .
Not a very good software ,
the software can be install in server and client ,in fact ,it can be set to server ,and can be set to client .
and in the client PC , PI interface server, data bridge(OPC client, named A) equal the OPC server to PI ICU.
but it recevie another data bridge (as OPC server,we call B) ,
when DCS guys update B data bridge, the A data bridge may be stop to giving data to PI ICU or PI ICU can not get any data from data bridge.
so we have to restart the data bridge A ,some time I have to inform DCS guys to restart B .
Once restart A , 80% tags back to normal .
but some tags need to be refresh in PI SMT .
Refresh means update PI tags's descriptor and a blank space ,and then wait some minute ,all the tags dont be "Time OUT "
