We know that there is no such thing as a 'standard' application. That's why a Sentinel RTU may be supplied and configured in an enormous variety of ways.

Here are some of the configuration options.

GSM/GPRS communications :

• GSM is the communication standard for all Sentinels
• SMS and GPRS are proven methods of message and data transfer
• GPRS is the most cost-effective method of data transfer for applications where data-logging is required
• SMS is simple and reliable for transmission of alarm messages

Modbus :

• Why Modbus?
• Modbus is used in multiple master-slave applications to monitor and program devices; to communicate between intelligent devices and sensors and instruments; to monitor field devices using PCs and HMIs. Modbus is also an ideal protocol for RTU applications where wireless communication is required. For this reason, it is used in innumerable gas and oil and substation applications. But Modbus is not only an industrial protocol. Building, infrastructure, transportation and energy applications also make use of its benefits.

ZigBee :

• Standard Modbus interfaces into ZigBee network
• Quick and low-cost installation
• Complete family of sensors and actuators
• Third part Modbus devices can be connected
