OPC variable Freelance 2013
I have a qvestion. I have Freelance 2013 witch is OPC client. I can read the variable from OPC server to digivis visualisation and trends. How can I use this variable in my PLC program, becouse when i use F2 key for reading variable to my program, i cant see variables from OPC.
It is posible use this variable in PLC program.
This was stated multiple times - controllers can't read OPC items, because it has no OPC client functionality. Both DigiVis and CBF have it, so You can design and operate graphics with OPC values.
The only way to change a OPC value "from" Controller is to have some OPC server to OPC server connection software, as Freelance OPC server has write to/read from controller functions. This way Your controller communicates with Freelance OPC server, which then connects with another server and synchronizes the data.
Hope it helps,
