Abstract

Methods and Systems are described for control at/of a network node. The network node can include a control module and first and second modules coupled to the control module. The first module can be configured to select first input/output (I/O) types of a field device coupled at an I/O interface of the network node. The second module can be configured to select a second I/O types of the field device. The first and second modules can be coupled to the I/O interface through a field device coupler.

First claim

What is claimed is:

1. A control system, the control system comprising:
a control node; and
a Single Signal Input/Output (SSIO) module coupled to a field device and the control node, the SSIO module configured to:
collect a first set of inputs from the coupled field device for a first duration;
monitor data included in the collected first set of inputs to detect a fault condition;
responsive to detection of the fault condition, instruct the coupled field device to capture and/or output a second set of inputs from the coupled field device;
collect the second set of inputs from the coupled field device for a second duration; and
identify an abnormal condition using data included in the collected first set of inputs and data included in the collected second set of inputs.

2. The system of claim 1 , wherein the SSIO module is further installed on a modular, mounting structure at a backbone and a field device coupler.

3. The system of claim 2 , wherein the mounting structure is a DIN rail mounted baseplate or a DIN rail.

4. The system of claim 1 , wherein the SSIO module is configured to access network data stored at a centralized datastore hosted at the control node.

5. The system of claim 1 , wherein the SSIO module is configured to access network data stored at the control node and/or at other network nodes.

6. The system of claim 1 , wherein the SSIO module is further configured to:
generate, on detection of the fault condition, SoE and/or TDR/TDA reports using the first and second sets of inputs;
identify the abnormal condition using the generated SoE and/or TDR/TDA reports; and
implement a counter measure based on the identified abnormal condition.

7. The system of claim 1 , further comprising a second SSIO module coupled to a second field device and the control node, wherein the SSIO module is further configured to:
scale the first and/or second set of inputs from the coupled field device;
generate control output variables using the scaled first and/or second set of inputs;
store the control output variables at a central datastore, and

wherein the second SSIO module is configured to:
retrieve the control output from the central datastore;
convert the control output variables into an output signal based on a first input type of the field device for receiving data by the field device and a second input type of the second field device for receiving data by the second field device; and
output the output signal to the second field device for controlling the second field device.

8. A method performed by a Single Signal Input/Output (SSIO) module coupled to a field device and a control node, the method comprising:
collecting a first set of inputs from a coupled field device for a first duration;
monitoring data included in the collected first set of inputs to detect a fault condition;
responsive to detection of the fault condition, instructing the coupled field device to capture and/or output a second set of inputs from the coupled field device;
collecting the second set of inputs from the coupled field device for a second duration; and
identifying an abnormal condition using data included in the collected first set of inputs and data included in the collected second set of inputs.

9. The method according to claim 8 , further comprising:
accessing network data stored at the control module node and/or at other network nodes.

10. The method according to claim 8 , further comprising:
accessing network data stored at a centralized datastore hosted at the control node.

11. The method according to claim 8 , further comprising:
generating, on detection of the fault condition, SoE and/or TDR/TDA reports using the first and second sets of inputs;
identifying the abnormal condition using the generated SoE and/or TDR/TDA reports; and
implementing a counter measure based on the identified abnormal condition.

12. A non-transitory computer-readable medium having stored thereon processor executable instructions, which when executed by a processor cause a Single Signal Input/Output (SSIO) module coupled to a field device and a control node to perform a method comprising:
collecting a first set of inputs from a coupled field device for a first duration;
monitoring data included in the collected first set of inputs to detect a fault condition;
responsive to detection of the fault condition, instructing the coupled field device to capture and/or output a second set of inputs from the coupled field device;
collecting the second set of inputs from the coupled field device for a second duration; and
identifying an abnormal condition using data included in the collected first set of inputs and data included in the collected second set of inputs.

13. The non-transitory computer-readable medium according to claim 12 , having stored thereon processor executable instructions, which when executed by the processor cause the SSIO module to perform:
accessing network data stored at the control module node and/or at other network nodes.

14. The non-transitory computer-readable medium according to claim 12 , having stored thereon processor executable instructions, which when executed by the processor cause the SSIO module to perform:
accessing network data stored at a centralized datastore hosted at the control node.

15. The non-transitory computer-readable medium according to claim 12 , having stored thereon processor executable instructions, which when executed by the processor cause the SSIO module to perform:
generating, on detection of the fault condition, SoE and/or TDR/TDA reports using the first and second sets of inputs;
identifying the abnormal condition using the generated SoE and/or TDR/TDA reports; and
implementing a counter measure based on the identified abnormal condition.
