OPC

[Indesh]

I have created an OPC..my variable are product,from/to and dwg no.(to)....

i have created 2 pids and this works fine i do get all my data automatically,

note that my frm/to are linked to the equipment tag...which works fine.

my issue is that if i have a line in pid 1 passing in pid 2 where a tie in is done and finally gos to pid 3 where it is connected to a vessel..

the results are as follows

pid 1 : it gives me the dwg number ,the product but not the from /to.

pid 2: it gives me all datas.

pid 3: it gives me the dwg number ,the product but not the from /to.

what i understand from the results is as if your common line jumps 1 pid it can't read...it reads only i pid after!!!!!

can anyone help please...

What happens if you disconnect the tie in on PID #2?
