Ctek’s SMS Gateway application provides an out-of-band (SMS) communications path for intelligent end-point controllers such as PLCs and custom industrial control solutions. The SMS Gateway application works in tandem with the standard communications capabilities of the SkyRouter during normal operation to determine the health of the bearer channel (network IP connection) and reacts to bearer channel failures by routing controller messages over the SMS network to a far end server. As an added benefit the SMS Gateway application makes controller information available to a conventional wireless handset upon request. Figure 1 depicts the basic architecture of the application.
