Abstract
The present invention provides methods, systems and computer program products for detecting a configuration error or operating error corresponding to an input/output (I/O) device. The I/O device comprises a plurality of I/O points configured to establish a combined I/O channel between said I/O device and a field device, said combined I/O channel comprising a primary I/O channel and at least one secondary I/O channel.
Claims19
A method of detecting a configuration error or operating error corresponding to an input/output (I/O) device comprising a plurality of I/O points configured to establish a combined I/O channel between said I/O device and a field device, said combined I/O channel comprising a primary I/O channel and at least one secondary I/O channel, the method comprising:
- receiving an instruction for transmission of a specified signal pattern over the combined I/O channel;
- responsive to the specified signal pattern:
- initiating at an I/O point associated with the primary I/O channel within the combined I/O channel, transmission of a primary channel signal over the primary I/O channel;
- for each secondary I/O channel within the combined I/O channel, initiating at an I/O point associated with said secondary channel, transmission of a secondary channel signal over said secondary I/O channel;
- receiving a record of signal transmissions initiated or received over the combined I/O channel in response to the specified signal pattern;
- comparing signal values within the received record of signal transmissions against a predefined set of signal values associated with the specified signal pattern;
- detecting a configuration error or operating error based on results of the comparison of signal values.
A system for detecting a configuration error or operating error corresponding to an input/output (I/O) device, comprising:
- an I/O device comprising a plurality of I/O points configured to establish a combined I/O channel between said I/O device and a field device, said combined I/O channel comprising a primary I/O channel and at least one secondary I/O channel;
- and
- a validation engine configured to:
- receive an instruction for transmission of a specified signal pattern over the combined I/O channel;
- responsive to the specified signal pattern:
- initiate at an I/O point associated with the primary I/O channel within the combined I/O channel, transmission of a primary channel signal over the primary I/O channel;
- for each secondary I/O channel within the combined I/O channel, initiate at an I/O point associated with said secondary channel, transmission of a secondary channel signal over said secondary I/O channel;
- receive a record of signal transmissions initiated or received over the combined I/O channel in response to the specified signal pattern;
- compare signal values within the received record of signal transmissions against a predefined set of signal values associated with the specified signal pattern;
- detect a configuration error or operating error based on results of the comparison of signal values.
A computer program product comprising a non-transitory computer readable medium having computer readable instruction embodied therein for detecting a configuration error or operating error corresponding to an input/output (I/O) device comprising a plurality of I/O points configured to establish a combined I/O channel between said I/O device and a field device, said combined I/O channel comprising a primary I/O channel and at least one secondary I/O channel, the computer readable instructions comprising instructions for:
- receiving an instruction for transmission of a specified signal pattern over the combined I/O channel;
- responsive to the specified signal pattern:
- initiating at an I/O point associated with the primary I/O channel within the combined I/O channel, transmission of a primary channel signal over the primary I/O channel;
- for each secondary I/O channel within the combined I/O channel, initiating at an I/O point associated with said secondary channel, transmission of a secondary channel signal over said secondary I/O channel;
- receiving a record of signal transmissions initiated or received over the combined I/O channel in response to the specified signal pattern;
- comparing signal values within the received record of signal transmissions against a predefined set of signal values associated with the specified signal pattern;
- detecting a configuration error or operating error based on results of the comparison of signal values.
