Hi tyalc,

You need to use OPC tagtypes. Firstly You need to initialize an OPC variable in CBF (see System > OPC item list). This allows You to see and use OPC variables in system. Then You need to prepare a OPC Tagtype (it's something like OPC faceplates). You may use some standard tagtypes for Freelance or AC 500 available under Freelance Export folder or create Your own Tagtype.

You may find more info on how to use OPC_FB-CLASS (name of Tagtype object in CBF) in Engineering manual - IEC 61131-3 Programing.

Hope this helps,

Mike
