Signal and a Numeric Value Selected
In this example, one signal (V1) and a numeric value (53.50) are selected for the Custom1
alarm to be triggered when [V1] > 53.50. The first operand chosen (top pull-down menu) is
Analog Inputs. The next pull-down menu shows that the Supervisor must select from a list of
inputs of that type. An operator is selected from the virtual keypad. The keypad is then changed
to numeric in order to enter a numeric value to complete the equation.
