Abstract

An appendable system includes a plurality of appendable devices that are adapted to interoperate with each other and/or a workstation via a communication network to monitor and/or control a process. Each of the appendable devices can communicate with one or more sensors and/or control outputs and includes a housing that facilitates mounting of the appendable device to a surface.

Claims

1. An appendable device, comprising:

a housing having a fastener configured to enable the appendable device to be mounted to a surface of an entity in a process control system;

a memory disposed within the housing;

an input/output interface disposed within the housing, wherein the input/output interface is adapted to communicate with at least one of a sensor or a control output operatively coupled to the appendable device; and

a processor disposed within the housing and communicatively coupled to the memory, wherein the processor is programmed to communicate with the input/output interface and to communicate information related to the at least one of the sensor or the control output, as the information becomes available, to another device via a communication network.

2. The appendable device of claim 1, wherein the processor is further programmed to enable the appendable device to perform at least a part of a closed-loop process control algorithm.

3. The appendable device of claim 1, wherein the processor is further programmed to diagnose a condition associated with at least one of the appendable device or a process associated with the appendable device.

4. The appendable device of claim 1, wherein the processor is further programmed to detect an alarm condition and to send alarm information to the other device via the communication network in response to detecting the alarm condition.

5. The appendable device of claim 1, wherein the other device is a wireless handheld device.

6. The appendable device of claim 1, wherein the processor is further programmed to enable the appendable device to function as a part of a communication path for another appendable device.

7. The appendable device of claim 1, wherein the at least one of the sensor or the control output operatively coupled to the appendable device is disposed within the housing.

8. The appendable device of claim 1, wherein the communication network uses at least one of a wireless or a hardwired communication technique.

9. The appendable device of claim 8, wherein the at least one of the wireless or the hardwired communication technique includes the use of an internet.

10. The appendable device of claim 1, further including a power source disposed within the housing and adapted to generate power in response to vibration of the surface.

11. The appendable device of claim 1, further including a power source disposed within the housing, wherein the power source uses at least one of a capacitor, a battery, a light or a magnetic field to provide power to the appendable device.

12. The appendable device of claim 1, wherein the fastener includes at least one of an adhesive, a screw, a clamp, a tie-wrap or a magnet.

13. The appendable device of claim 1, wherein the housing is adapted to be mounted within at least one of a rugged environment or a hazardous environment.

14. An appendable device, comprising:

a housing having a fastener configured to facilitate surface mounting of the appendable device to an entity in a process control system;

a power source disposed within the housing;

a transceiver disposed within the housing;

an antenna coupled to the transceiver and adjacent to the housing;

a memory disposed within the housing;

an input/output interface disposed within the housing;

a sensor coupled to the input/output interface; and

a processor communicatively coupled to the memory, the transceiver and the input/output interface, wherein the processor is adapted to execute software stored in the memory to sense a parameter using the sensor and to use the transceiver and the antenna to transmit information associated with the sensed parameter to another device via a wireless communication network as the information becomes available.

15. The appendable device of claim 14, wherein the fastener includes at least one of an adhesive, a screw, a clamp, a magnet or a tie-wrap.

16. The appendable device of claim 14, wherein the power source is adapted to generate power in response to vibration of the surface.
