The Sixnet series RAM industrial cellular RTUs now feature a Web-based, user-configurable event engine that can trigger I/O and relays or send SMS text messages based on real-time operational data. With connectivity options such as I/O, serial, Ethernet and optional Wi-Fi, RAM RTUs can integrate with existing equipment to provide a remote-monitoring M2M technology that performs local control and alerts personnel of critical events. For example, the event engine can be configured to trigger actions when predefined alarm values, such as an excessively high tank level or an out-of-range pressure level, are met.
