For diagnostics and debugging expressions Monokot Server Administrator provides the Go Online mode. In the Go Online mode, the following additional expression information is available:
- Actual: contains the value of the expression
- Status: contains the current tag status, e.g. Good, BadLicenseExpired
- Update Time: contains the time (UTC) of the last expression update
To read expression values, the following requirements must be met:
- The user (specified in the credentials for connection) must have the read access rights
The Go Online mode does not use the OPC UA technology. Instead, it uses the server's built-in mechanism of data access via HTTPS (Web API). You can read more about this here.
