Associated with: SCADAPack 50 Outstations.
This status attribute shows the date and time by which a confirmation response, sent by the device, needs to be received by ClearSCADA to be valid. After this time, ClearSCADA will flag the confirmation response as unexpected, although it will process the confirmation. There can be significant delays in sending and receiving SMS messages, even when ClearSCADA and the device are operating normally. This is because the GSM network may be busy or the device may be in Sleep mode.
