ALPHABETIC REFERENCE EXCEL CARE CONTROL ICONS74-5577–33 (US) 142EN2B-0184 GE51 R0518 (Europe)Minimum / MINFunction Returns the lowest value of all inputs.For example, in control technology, continuous positioning signals are oftencalculated using mathematical functions. These functions are defined for the entireset of real numbers, while positioning signals are typically valid only for a subset ofnumbers, for example, 0 to 100 percent.You can use the MIN icon to define the maximum output value to a signal. If, forexample, a function outputs a value above 100, you can use MIN to select either thefunction output or 100, whichever is lower.I/O Dialog BoxExcel Web / Excel Web IIInputs Two through six analog inputs (X1 through X6, Excel Web / Excel Web II: 32 inputs,1 to 32). Minimum two inputs.You can enter the first input as a parameter (engineering unit index number andvalue).Output One analog output (Y).Internal Parameters None.Parameter NumberDescriptions None.Example See Positioning Signal Limitation in the Examples chapter for an application thatuses the MIN and MAX icons to limit an output signal.Also see the Duty Cycle (DUC) section. You can use MIN to calculate an input valuefor lowest zone temperature.
