Dear all,
I have two plcs connected via ethernet to wincc flexible 2008 sp2.
First PLC is s7-300, and it is connected directly (connection 1)
Second PLC is Unitronics, ant it is connected via UniOPC server. (sonnection 2)
In WinCC flexi i have created tags...
First tag is integer from s7-300 (tag 1)
Second tag is integer from Unitronics (integer from uniOPC) (tag 2)
Now I nead to copy or transfer value of second tag form unitronics to first tag form s7-300.
Simplified, i nead that value form Unitronics PLC (tag 2) goes to s7-300 PLC (tag 1). And that is going cyclicly.
I can not connect two plcs directly....
Please send me some helpfull information.
