Security configuration for PI Interface for OPC DA

Most OPC servers do not support OPC security. Verify that your OPC server supports security before enabling this option. If your OPC server requires clients to use OPC security, enable OPC security and select NT security or Private OPC security, then enter the user ID and password.

Note: OSIsoft recommends using NT security to encrypt user ID and password information. Private OPC security stores and transmits this information in clear text. See the Security best practices for PI interface for OPC DA.
