Function Description ExamplesMEDIAN(range)SUMSQ(range)PROD(range)MAX(range)MIN(range)AVG(range)SUM(range)RAND(low,high)Returns the median of all values in parenthesis. Rangecan be a set of constants or input variable separated bycommas, or a range of inputs designated by a colonbetween the two ends of the range (e.g. AI1:AI7).Returns the sum-square of all values in parenthesis.Each input or constant is squared, and then addedtogether. Range can be a set of constants or input variableseparated by commas, or a range of inputs designatedby a colon between the two ends of the range(e.g. AI1:AI7).Returns the product of all values in the range multipliedtogether. Range can be a set of constants or inputvariable separated by commas, or a range of inputsdesignated by a colon between the two ends of therange (e.g. AI1:AI7).Returns the maximum value of all values in the range.Range can be a set of constants or input variable separatedby commas, or a range of inputs designated by acolon between the two ends of the range (e.g.AI1:AI7).Returns the minimum value of all values in the range.Range can be a set of constants or input variable separatedby commas, or a range of inputs designated by acolon between the two ends of the range (e.g.AI1:AI7).Returns the average value of all values in the range.Range can be a set of constants or input variable separatedby commas, or a range of inputs designated by acolon between the two ends of the range (e.g.AI1:AI7).Returns the sum of all values in the range. Range canbe a set of constants or input variable separated bycommas, or a range of inputs designated by a colonbetween the two ends of the range (e.g. AI1:AI7).Returns a random number between low and high everytime the algorithm is updated (every few seconds).MEDIAN(3,7,8,14) result: 7.5MEDIAN(AI1,AI4)MEDIAN(AI1:AI7)SUMSQ(5,4,3) result: 50SUMSQ(AI1:AI7) result: sum-square ofall seven inputsPROD(2,3,4) result: 24PROD(AI1,AI4)PROD(AI1:AI7)MAX(2,5,7,14) result: 14MAX(AI1,AI4)MAX(AI1:AI7)MIN(2,5,7,14) result: 2MIN(AI1,AI4)MIN(AI1:AI7)AVG(2,5,7,14) result: 7AVG(AI1,AI4)AVG(AI1:AI7)SUM(2,5,7,14) result: 28SUM(AI1,AI4)SUM(AI1:AI7)RAND(1,10) result: random numberfrom 1 to 10Table 2-9 - Extended Math Functions2-8 • E2 User’s Manual Supplement: Flexible Combiner 026-1620 Rev 0 09-15-05
2.4.2 Extended Logical FunctionsFunction Description ExamplesCUTINOUT(test, low, high,between)COUNT(range)VOTE(range)AND(range)OR(range)XOR(range)Returns a 1.0 or a 0.0 based on the following:If test is below low, the result is 0.0If test is above high, the result is 1.0If test is between the value of low and high, the resultwill be equal to between. This should be filled by thename of the same output you are building the equationfor so that when test is between, the output remains inwhatever state it’s in, thus creating a hysteresisbetween the cut-in and cut-out setpoints.Returns the number of values in the specified rangethat are non-zero. Typically used with digital inputs tocount the number of ON inputs. Range can be a set ofconstants or input variable separated by commas, or arange of inputs designated by a colon between the twoends of the range (e.g. DI1:DI7).Returns a 1.0 if more that 50% of the values in therange are non-zero, otherwise returns 0.0. This meansif the range contains an even number of values, thenumber of non-zero inputs must be more than half toyield a result of 1.0. Range can be a set of constants orinput variable separated by commas, or a range ofinputs designated by a colon between the two ends ofthe range (e.g. DI1:DI7).Returns a 1.0 only when all values in the range arenon-zero, and 0.0 if one or all values are zero. Rangecan be a set of constants or input variable separated bycommas, or a range of inputs designated by a colonbetween the two ends of the range (e.g. DI1:DI7).Returns a 1.0 when one or all values in the range arenon-zero, and 0.0 if all values are zero. Range can be aset of constants or input variable separated by commas,or a range of inputs designated by a colonbetween the two ends of the range (e.g. DI1:DI7).Same as OR, except returns 0.0 when all values arenon-zero.CUTINOUT(-4,5,12,DO1) result: 0.0(low)CUTINOUT(14,5,12,DO1) result: 1.0(high)CUTINOUT(7,5,12,DO1) result: DO1(between)COUNT(0,0,1,0,1) result: 2COUNT(0,0,0,0) result: 0COUNT(DI1,DI4)COUNT(DI1:DI7)VOTE(0,0,1,0) result: 0.0VOTE(0,0,1,1) result: 0.0 (not morethan half non-zero in range)VOTE(1,1,1,0) result: 1.0VOTE(DI1,DI4)VOTE(DI1:DI7)AND(1,1) result: 1.0AND(0,1) result: 0.0AND(1,1,1,1,0) result: 0.0AND(DI1,DI4)AND(DI1:DI7)OR(1,1) result: 1.0OR(0,1) result: 1.0OR(0,0,0,0,0) result: 0.0OR(DI1,DI4)OR(DI1:DI7)XOR(1,1) result: 0.0XOR(0,1) result: 1.0XOR(0,0,0,0,0) result: 0.0XOR(DI1,DI4)XOR(DI1:DI7)Table 2-10 - Extended Math FunctionsFunctions Functions • 2-9
