Associated with: SCADAPack 50 Outstations.
When you send a configuration change to a SCADAPack 50 device, or initiate an action, ClearSCADA sends these in one or more SMS message requests. When the device receives the message or messages, it sends a confirmation SMS message back to ClearSCADA. This process does not necessarily take place immediately. This may be because the GSM network is busy or the device may be in Sleep mode. Therefore, there can be significant delays in sending and receiving messages even when ClearSCADA and the device are operating normally.
