Can I use an Opc item into a program in Freelance 2016?
Hello I am trying to send some varibles configured in Freelances to another OPC Server. Actually I can to use the opc items in graphics and also in push buttons to send command in OPC Items.
But my customers requires that some variables of Freelance be send to another OPC, for example : if Freelance has a Pressure Transmitter, the other OPC (third) needs to read that measure from Freelance
Thanks a lot

You need to configure an OPC Server in Freelance 2016 and then you may define variables of your system be available to other 3rd Party OPC.

Usually, an OPC client can connect to multiple OPC servers. From that viewpoint, there is no need to send data from one OPC server to another.
In case you need all data in one OPC server you can use OPC server in a hierarchical topology, where the one OPC server needs to have an OPC client on the south side so it can sit on top of several other OPC servers. There is 3rd party software available that does that. I remember something like KepServerEX. Google it.
A third method is to send the measurement data from Freelance to the system with the one OPC server via Modbus-TCP. That requires the third party OPC server to be part of a system which has a PLC or controller that speaks Modbus-TCP.
