EXCEL CARE CONTROL ICONS ALPHABETIC REFERENCE71 74-5577–33 (US)EN2B-0184 GE51 R0518 (Europe)Factorial (Excel Web / Excel Web II)Function Calculates the factorial of the input (e.g. 5!=1*2*3*4*5).I/O Dialog BoxInput One analog input (X).Output One analog output (X!).Internal Parameters None.Fixed Applications (XFM)Function Extended Function Modules (XFMs) are applications (or subprograms) that cancombine with other control icons, subprograms, or points to provide additionalcontrol strategy functionality.When you select and place the XFM icon from the Control Strategy tool bar, theLoad submodules dialog box displays with a list of subprograms from the XFMlibrary.Dialog BoxSubprogram Listenth.csd ENTHALPY H,X control in English units (temperatures in Fahrenheit).epid.csd ENHANCED PID PID with additional features such as built-in start-up ramp,direct-reverse action selection, integral recalculation toprevent windup below minimum/above maximum, and anauxiliary input for limit applications and integral reset.flow.csd FLOW Output is a calculated flow rate. Input is from a flow sensor(air, gas, water, etc.).lead-lag.csd LEAD-LAG This XFM controls two devices with lead-lag logic.
