Runtime Control
The Service must be in Runtime mode in order to process values for trending, alarming, data logging, recipe execution, report generation, data transfer, and communications. You can Start and Stop Runtime from any of the Service configuration windows.
To Start Runtime select the Start Runtime Button in any Service modification window of the OAS Configuration application or from the OAS Service Control application.
To Stop Runtime select the Stop Runtime Button in any Service modification window of the OAS Configuration application or from the OAS Service Control application.
You can make add, delete or make modifications to all configurations while the Service is in Runtime mode. Tag configurations files can only be loaded when not in Runtime, but Tag configuration files can be saved during Runtime. All other modifications can be done while in Runtime if desired.
Make certain to save the modifications if you desire the changes to be retentive for the next time the Service is started.
Selecting Live Data Cloud Service
If one or more Live Data Cloud services are subscribed to the service you are connecting to the Live Data Cloud list will populate with all of the remote Live Data Cloud services that are available to connect to. Use the Select button to the right of the Live Data Cloud list to connect to the Live Data Cloud service for remote configuration.
See Live Data Cloud for more information on how to setup Remote SCADA Hosting to host a remote data source through a standard Internet connection.
Selecting Service
When accessing any of the configurations you will select the desired network node to modify. Enter the IP Address, Network Node Name, or Registered Domain Name in the Network Node field and click the Select. This allows you to modify configurations on remote systems.
Use the pull down to select previously selected services. Use the EDIT button to add additional network nodes to the pull-down list.
If other Live Data Cloud nodes are hosted through selected network node the Live Data Cloud list will populate in the Live Data Cloud pull-down.

If successfully connected to the OAS Engine the status of the service will appear at the top along with configuration buttons to load, save, and modify a configuration.
FAQs – Windows Services
Remoting Security
The OAS Service communicates with other OAS Services and local and remote .NET applications, Excel Workbooks, and OPCSystems.NET OPC Servers over TCP port. The default TCP port number that Open Automation Software uses is 58727. If you have a firewall simply add this port number in the exceptions list. The TCP port is adjustable using the Configure OAS application under Configure-Options as the TCP Port Number. You can also set the TCPPortNumber property in all .NET controls, Excel Workbooks, and OPCSystems.NET OPC Server.
To add a port to the exceptions list select Control Panel-Windows Firewall, then the Exceptions Tab. Use the Add Port button to add the TCP Port 58727 for both inbound and outbound traffic.
For remote connections you can either use a Network Node name, IP Address, or registered Internet domain name of the remote nodes.
Communications to the Open UIEngine, web applications using Web HMI, Web Trend, Web Alarm, and the OAS REST API are performed by default through TCP Port 58725. This can be changed under Configure-Options-Networking.
