Is there a limit to the number of OPC clients that can connect to one OPC Server?
The OPC specifications do not provide any limitations on the number of OPC clients that can connect to a single OPC server. These limits should be dictated by hardware or network factors. It is possible that the OPC vendor has imposed limitations due to licensing, architecture, security or performance reasons. You should always check with the vendor for any limits before planning any OPC architecture.
