CHAPTER 4
Using the Gateway
Definition of RTUs
All RTU groups, RTUs, routes and sensors for which a user has no
configuration read access rights granted are hidden for this user by
the GUI.
Note: For example, they may not be shown in the RTU network
tree or in any table view.
A Remote Telemetry Unit (RTU) includes one or more sensors to
measure specific conditions of the environment in which it is
placed (e.g. temperature, humidity or the current level of a river)
and a unit to transmit the measured data. A network of RTUs can
be placed within large areas to observe the conditions from differ-
ent points. The receiving person bases specific reactions on the
measured data, e.g. a farmer starts to water his fields if the mea-
sured rain fall was too less, or he begins to carry out precautions if
the measured level of a river reaches a critical height.
The management of the RTUs within such a network is a task to be
performed by a Telemetry Gateway like the A850.
In order to define a RTU, to connect a sensor, to make a change or
to pass an order, a click with the right button of the mouse is to be
made while the pointer marks a RTU or RTU group, respectively,
whereupon the following context menu will appear:
RTU Context Menu
The RTU Context Menu allows to select and to execute all actions
related to RTUs, according to the respective descriptions referred
to in the following overview.
