To stop the plc while staying logged in, I need to use the <onlineapp>.stop(). The problem is that I'm not able to keep the declaration of the <onlineapp> to a next run of the script.

How could I program for this question knowing that there is nothing as <active_online_application> in the scriptEngine help?</active_online_application></onlineapp></onlineapp></p>

<p>ScriptEngine has no need to remember which online application exists because it is not necessary. Just create a new online application and check if it is logged in. If not, login and stop the running app.</p>

<p>I could manage to write a script that creates an online application, log-in, and start the PLC as shown in the below function code. <br/>
def plc_start(): <br/>
onlineapp = online.create_online_application(None)<br/>
onlineapp.login(0,True)<br/>
plc_login()<br/>
onlineapp.start()<br/>
print("started")</p>
