SVM-X77 AT commando special
A special version of the SVM modem was developed for the 24/7 monitoring of a PLC or SCADA system: the SVM-X77. Via a Watchdog, the SVM-X77 determines whether the PLC or the SCADA system is still functioning properly. The alarm device will issue an alert when the connection to the PLC or the SCADA system is lost.
