RTU ADDON

1 . A RTU (Remote Terminal Unit) add on device that can be connected into a networked sensor platform to enable its integration with industrial controllers and industrial control systems (ICS) without the need of a network, the device comprising:

one RTU add on device connected with a sensor platform's base unit;

the base unit is the logical module to which sensors are connected;

the base unit makes the values of digital or analog sensors available over an IP communication network to other applications, modules, or users;

the RTU add on device connects, like a sensor, to the base unit;

creation of a bridge between IP based sensor platforms and legacy ICS;

communication between the sensor and the base unit can be digital or analog using a wired or wireless connection, or any combination thereof; and

the add on device making the data from the sensor platform available to an ICS and other systems using industrial wired protocols.

2 . The RTU add on device of claim 1 , wherein the RTU add on device shows just one such RTU add on device, multiple could be used in a same configuration.

3 . The RTU add on device of claim 1 , wherein the RTU add on device has a wired or wireless connection to the base unit.

4 . The RTU add on device of claim 1 , wherein the RTU add on device connected direct or indirectly to the base unit.

5 . The RTU add on device of claim 3 , wherein connecting to an existing wired or wireless sensor port makes the RTU add on device backwards compatible to existing sensor deployments.

6 . The RTU add on device of claim 1 , enabling

connecting a sensor solution directly to an ICS without requiring a network; and

ensuring that sensor data is available to the ICS regardless of the state of the network.

7 . The RTU add on device of claim 1 ,

connected to an available sensor port on the base unit, an expansion hub of the base unit, or a physical connector.

8 . The RTU add on device of claim 3 , wherein

the wireless connection of the RTU add on device and the base unit or any other component is part of the sensor solution and before the networked IP connection.

9 . The RTU add on device of claim 1 , wherein

the RTU add on device connects to a sensor platform's base unit using the same connectivity offered to sensors or expansion units; being it based on a wired or wireless connectivity.

10 . The RTU add on device of claim 1 , wherein

the RTU add on device connects to a non-sensor port of the platform's base unit or expansion unit.

11 . The RTU add on device of claim 1 , wherein

the RTU add on device connects using any type of wireless communication to the base unit or another device inside the sensor platform and before the networked IP connection.

12 . The RTU add on device of claim 1 , wherein

the connection sends data in a bi-directional way between sensor and base unit; and

if it is a wired connection, then the base unit also provides power to the RTU add on device.

13 . The RTU add on device of claim 1 , wherein

sensors can be any type of analog or digital sensors or any combination thereof;

sensors can be connected in a wired or wireless way with the base unit; and

sensors can serve a single purpose or feature multiple different measurements in one same or multiple enclosure.

14 . The RTU add on device of claim 1 , wherein

the IP connectivity of the base unit is either wireless or wired; direct or indirect; or any combination thereof.

15 . The RTU add on device of claim 1 , wherein

the RTU add on device plugs into an available sensor port of the base unit or expansion unit using a cable which provides power and data transfer between the invention and the base or expansion unit; and

the base unit connects to an IP network and makes the data available over one or more network protocols to applications & systems.

15 . The RTU add on device of claim 1 , wherein

the RTU addon device connects to a port reserved for addons in general or ICS communication in particular.
