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.
