Hi,

we have an http based daemon service running. When the program is running, we want to inform the daemon service over http protocol whenever a cycle is completed or duration of idle time. Basically, I am storing the cycle counter or idle time duration in URScript variables.

```
public void generateScript(ScriptWriter writer) {
	writer.writeChildren();
	Variable variable = getSelectedVariable();
	if (variable != null) {
		String resolvedVariableName = writer.getResolvedVariableName(variable);
		writer.appendLine(resolvedVariableName + "=" + resolvedVariableName + "+1");
    }}

```

Can I access the URScript variables using Realtime client or RTDE interfaces from daemon service?

What is the best way to do?

Thanks,
