MessengerPro Service for write access of Signals


Enable the write access of i4scada Signals for MessengePro, using the Module Signals in the Studio Settings section.

MessengerPro supports the following services:

  • Email

  • Fax

  • SMS

  • Voice

  • OPC Items (i4scada Signals)

A Subscriber can have one or more of those services to get in contact with him. An OPC item could be a lamb or a horn that informs the subscriber about the alarming. For that, the signal must be permitted for MessengerPro inside the “Module Signals” configuration in the i4scada Studio.


Enable MessengerPro for Module Signals

Since MessengerPro service does not have direct contact with PLC, the i4scada server must run to use this feature. But the write request from MessengerPro to i4scada Server is buffered, if the Server is currently not available (for example a restart after a maintenance job).
