which port should be opened between PI OPC DA interface and PI Data Archive except 5450? thanks in advance for your answer and help.
Hi gao shuai,
All communication with the PI Data Archive is over port 5450. When PI Interface for OPC DA connects to the PI Data Archive it initiates a series of connections from an arbitrarily selected "ephemeral" port (chosen by the operating system) on the client computer to port 5450 on the PI Data Archive. No other special port is needed.
