Hello Chris, unfortunately the OPCDemo OPC-Server only serves a fixed set of different values/functions. But the user has the possibility to modify e.g. the Sine function which is delievered:
An original SINE item is: SINE:0.0..8.0:2.0 if you modify the name of the OPC-URL to SINE:-1.0..1.0:1.0 you can create a new item which delievers a sine from -1 to 1 with a periodicity of 2*1=3D 2 seconds. The OPCDemo OPC-Server now lists this new item in the group Created Items. Regards, Andreas W=FCrl NI Germany
