OPC-Server V2.2 Introduction Often wish a customer.2009-06-05 (Build:5731. Implementation and Application".3. 5. therefore the OPC-Server V2. The idea of this application based on the example in the OPC Book. witch is included in most of the MS Office programs.3.3. AC500 PM564(FW) : V1. OPC Book. Used documents: 1. a simple tool which makes him possible to set values in the PLC. In this book described Frank Iwanitz and Jürgen Lange how it is possible to communicate with VBA (MS Visual Basic for Application).3. observe these values and work on and on with these values in a calculation tool like Microsoft (MS) Excel.
