Overview

Starting point
The battery-powered SIMATIC RTU30X1C is used to monitor and control remote
stations that are geographically distributed and not connected to a power supply
network. The RTU30X1C can store process data and transmit it to a central station
via mobile wireless or via the LAN interface and an external router.
Furthermore, the RTU30X1C has 4 additional digital outputs and supports position
determination and time synchronization via GPS.
Requirements
An RTU30X1C monitors the fill level of a rain overflow basin.
To conserve power, the RTU30X1C is in sleep mode much of the time, switching to
an update or communication mode in predetermined cycles.
If the level exceeds a critical value, the RTU30X1C informs the operator by email
and SMS, even outside scheduled communication cycles.
In addition, the RTU30X1C informs the operator via SMS when its predefined
target position is reached. The actual position should be within a parameterized
radius.
