• When you check the status of the instances (sapcontrol -nr <instance number> -function GetSystemInstanceList), you get the following result:
  
    GetSystemInstanceList
    OK
    hostname, instanceNr, httpPort, httpsPort, startPriority, features, dispstatus
    <hostname>, <instance number>, ..., ... , ..., ABAP|GATEWAY|ICMAN|IGS, GREEN

                <hostname>, <instance number>, ..., ... , ..., ABAP|GATEWAY|ICMAN|IGS, GREEN

                 It does not list ASCS instance in the output.
