Connection Functions

Connection functions allow you to manage connections on the inSCADA platform with script/expression. With these functions you can run, stop and check the status of connections.

Get Connection Status

String ins.getConnectionStatus(String connectionName)

Provides information about the status of a connection.
connectionName: The connection name.
Return Value: Returns a string containing information about the connection status. ("Connected","Disconnected")

Syntax

var status=ins.getConnectionStatus("Connection_01");
if (status==="Disconnected") {
ins.notify("error","Connection 01","Connection 01 is fail");
}

String ins.getConnectionStatus(Integer connectionId)

Returns information about a connection status.
connectionId: The ID of the connection.
Return Value: Returns a string containing information about the connection status. ("Connected","Disconnected")

Syntax

var connectionId=1;
var status=ins.getConnectionStatus("Connection_01");
if (status==="Disconnected") {
ins.notify("error","Connection 01","Connection 01 is fail");
}
ConnectionId is a unique registration number in the database on connections in the inSCADA Platform. It is not displayed on the platform. However, this information can be taken from value expression using the self expression (self.connectionId). This allows you to write expressions that can check the overall connection status.

Start Connection

startConnection(String connectionName)

Starts a connection.
connectionName: The connection name.
Return Value: Does not return any value.
if (ins.getConnectionStatus("Connection_01")==="Disconnected") {
ins.startConnection("Connection_01");
}

Stop Connection

stopConnection(String connectionName)

Stops a connection.
connectionName: The connection name.
Return Value: Does not return any value.

Syntax

if (ins.getConnectionStatus("Connection_01")==="Connected") {
ins.stopConnection("Connection_01");
}
