<\/p>\nThe Logic components evaluate an input against some simple logic.<\/p>\n
The Digital State component supplies the logic for detecting a simple digital state.<\/p>\n
It allows you to evaluate a text data point against specified values, and evaluate the result as either true or false.<\/p>\n
<\/p>\n
Properties<\/p>\n
Case sensitive comparison?<\/p>\n
This check box, if selected, allows strings to be compared on the basis of upper and lower-case letters. For example, String <\/strong>will be considered as being different to string<\/strong>.<\/p>\n Inputs<\/p>\n Flow The component that causes the digital state logic to execute should be connected to the flow pin for this component.<\/p>\n Text This input is mandatory and is the input data point.This input is required. Not connecting this pin will produce an error.<\/p>\n T\u00a0 The state text that is matched to produce a value of true. This input is required. Not connecting this pin will produce an error.<\/p>\n F\u00a0 The state text that is matched to produce a value of false. This input is required. Not connecting this pin will produce an error.<\/p>\n Outputs<\/p>\n Boolean Following evaluation, the true or false value is output from this pin. Not connecting this pin will produce a warning.<\/p>\n err\u00a0 If in <\/strong>does not match either state T<\/strong> or F<\/strong>, the process follows this path.<\/p>\n Example<\/p>\n In the following example, two events may be raised.<\/p>\n If the input is a string, the Digital State component is run. The string is then evaluated to see if it is equal to One or Zero.<\/p>\n The state of the entity changes to Online when the input is evaluated as true (input is \"One\").<\/p>\n The state of the entity changes to Offline when the input is evaluated as false (input is \"Zero\").<\/p>\n The Drift Detector component supplies the logic for detecting the deviation between process data inputs and reference inputs. The reference inputs can be a fixed value, or it can be a dynamic value from another data stream.<\/p>\n Properties<\/p>\n Limit Offset Mode<\/p>\n Absolute or Percentage. Indicate whether to specify actual values for the upper and lower limits, or whether to specify the upper and lower limits as a percentage offset from the target value.<\/p>\n Inputs<\/p>\n The input pins are mandatory. If they are not connected, the component will not be able to run.<\/p>\n Flow\u00a0 The component that causes the drift detection logic to execute should be connected to the flow pin for this component.<\/p>\n in This input is mandatory and is the input data stream. This input is required. Not connecting this pin will produce an error.<\/p>\n target\u00a0 The target value. This input is required. Not connecting this pin will produce an error.<\/p>\n upper\u00a0 The upper limit value or percentage offset from the target value.<\/p>\n lower\u00a0 The lower limit value or percentage offset from the target value.<\/p>\n Outputs<\/p>\n The output pins are optional. Not connecting an output pin will produce a warning.<\/p>\n above\u00a0 If the input value is above the upper limit, the process follows this path.<\/p>\n normal\u00a0 If the input value is between the upper limit and lower limit, the process follows this path.<\/p>\n below\u00a0 If the input value is below the lower limit, the process follows this path.<\/p>\n Example<\/p>\n In the following example, three events may be raised.<\/p>\n Data is fetched from four sources. The value is then evaluated against the target, upper limit, and lower limit.<\/p>\n The state of the entity changes to Above when the input is evaluated as being above the upper limit.<\/p>\n The state of the entity changes to Below when the input is evaluated as being below the lower limit.<\/p>\n The state of the entity changes to Within when the input is evaluated as being between the upper limit and lower limit.<\/p>\n The Range Checker component supplies the logic for detecting the deviation between process data inputs and reference inputs. The reference inputs can be a fixed value, or it can be a dynamic value from another data stream.<\/p>\n Properties<\/p>\n This component has no additional properties.<\/p>\n Inputs<\/p>\n The input pins are mandatory. If they are not connected, the component will not be able to run.<\/p>\n Flow\u00a0 The component that causes the range checker logic to execute should be connected to the flow pin for this component.<\/p>\n in\u00a0 This input is mandatory and is the input data stream. Not supplying this input pin will produce an error and the process will not run.<\/p>\n max\u00a0 The maximum value the input should have.<\/p>\n min\u00a0 The minimum value the input should have.<\/p>\n Outputs<\/p>\n The output pins are optional. Not connecting an output pin will produce a warning.<\/p>\n above\u00a0 If the input value is greater than the maximum value, the process follows this path.<\/p>\n normal\u00a0 If the input value is between the maximum and minimum values, the process follows this path.<\/p>\n![\"\"](\"https:\/\/oihelp.corporate.ifs.com\/help\/wp-content\/uploads\/2018\/12\/word-image-18.png\")
