Thank you for your response.
My responses to your comments are as follows:
Does the OPC sniffer work with classic OPC (Midcrosoft OLE) or UPC UA? Matrikon OPC sniffer is for classic OPC supporting OPC DA 2.0 and 1.0a specifications.
Let me rephrase my questions again to help you answer precisely: Do you mean to install 2 different Rapid SCADA on one machine? Is it possible to run the HelloWorld project and DemoPrject simultaneously in one machine?
Agent automatically decides whether to restart or not. It depends what settings was changed.
When uploading a project to the server, there are two options to restart the server and communicator. When uploading the OPC Project I intentionally unchecked these two options. The reading and writing operations to the OPC are not working properly at the workstation. However, they worked as intended when both options are checked during configuration upload.
