From OpenSCADAWiki
From this tab you can set:
- The state of the controller object, as follows: Status, "Enabled", "Running" and the name of the storage containing the configuration.
Manual restart of the enabled controller object causes the force reformation of the monitored items list.
- Identifier, name and description of the controller.
- The state "Enabled" and "Running", in which the controller object must be translated at boot.
- Scheduling policy and priority of the task of the data acquisition.
- Period of synchronization of the configuration of attributes of the parameters with the remote station, and try time for the connection restore.
- URL of the endpoint node of the remote station — OPC-UA server. In begin, the address you can point as "opc.tcp://{IP|name}:{port}", after that, at the controller's object enable and allowing the pointed OPC-UA node, there will be emerged to select the refined address.
- Often there meets a situation when the refined address is symbolic which does not resolve into the network by the server incorrect configuration. In this cases you need to keep the original IP-address or the name which resolved to the correct IP.
- Security policy and mode of the messaging security.
- Client certificate and private key in the PEM format.
- Hidden in the running state.
- User and password to authenticate on the server, empty value here enable the anonymous access.
- Asynchronous write. Enables asynchronously writing of the changes to the controller, in the general acquisition cycle and after the data acquisition itself, blocking of reading the written values on one cycle (before the writing buffer clearing).
- This mode also prevents for loss the writing data at the connection loss and the wrote data will be transmitted just the connection will be restored.
- Use the "Read" function, otherwise there is activated and used the Publish (asynchronous) data acquisition service of the OPC-UA protocol.
