Using the AC500 within Freelance 2016
Hello, I am a student researching the possibilities of the AC500. I have been able to use the AC500 within Freelance 2016 by using the CoDeSys OPC server.
My question is: does Freelance 2016 have any special AC500 functions? And is it possible to directly connect the AC500 to Freelance without using OPC? (for example using Modbus/TCP)

You may use OPC, as well as any fieldbus that is available for both Freelance and AC500 (for example Modbus RTU and TCP).
The additional value of using the OPC connections are OPC_Tag_types_for_AC500 available in Freelance. These are ready Faceplates for AC 500 that use OPC variables and can be initialized half-automatic (You must import them and initialize - then You get ready Faceplates for Function Blocks in Your AC 500, which are visible as normal faceplate in Freelance Operations/DigiVis).
Hope this helps,
