MessengerPro supports observation of the GSM modem if the SMS confirmation for that GSM modem is active. The observation is done before MessengerPro checks for incoming SMS confirmation request messages. The polling time can be configured inside i4SCADA (Service SMS, Register tab confirmation)

The observation result is written to some internal i4SCADA signals:

  • GSM_Modem_SignalStrength

    • 0..31: Current Signal Strength of mobile phone connection

    • -1: Unknown

  • GSM_Modem_Online

    • 0: Not Online

    • 1: Online

    • 2: Online with roaming

  • GSM_Modem_Error

    • 0: No Error

    • Other values are device specific errors

Note

To use GMS Observation a registry key “ObserverGsm” must be set to 1.

Create a new string type Registry under this path: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\WEBFACTORY\WFMessenger\2.00\Settings. In case the Keys/Folders registry does not exist it should be also manually added.
