Condition Monitoring Unit CMU 1000 Page 79 7 CM Program Functions A CM program consists of many individual functions that are linked with one another and that are processed and evaluated in cyclical fashion. 7.1 General Information Concerning Functions A function has Inputs, Outputs and Parameters. This means, for example, the function "Median value" reads a numerical value at the input, forms a median value above it and then displays this at the output.
Condition Monitoring Unit CMU 1000 Page 80 7.1.2 Parameters Parameters are defined in the Editor and do not change during the running time. An exception to this are the input parameters, which can be modified in a menu on the CMU or with a connected PC during the running time. Parameters have one of the following types: 7.1.2.1 Numerical Parameters A numerical parameter is a decimal number in accordance with the inputs/outputs. 7.1.2.2 Whole Number A whole number is a natural number, i.e.
Condition Monitoring Unit CMU 1000 Page 81 7.2 Data Sources 7.2.1 Numerical Constant The Numerical Constant function supplies a numerical value which is defined in the Editor and which does not change during the running time. That means that the Value parameter entered in the Editor is output during the running time at the output. Inputs: Outputs: Parameters: y: p1: (Numerical) Value (Numerical) 7.2.2 Measured Value The Measured Value function provides the current measured value of a connected sensor.
Condition Monitoring Unit CMU 1000 Page 82 7.2.4 Numerical Entry The function Numerical input supplies a numerical value which can be adjusted in the Parameters menu of the CM device. As an alternative, it can also be set through a connected PC. The Inscription parameter is used as a menu option in the input menu for this purpose. The permissible input range runs from -2,000,000.000 to +2,000,000.000. Modifications made in the CM device during the running time also remain in effect after switch-off.
Condition Monitoring Unit CMU 1000 Page 83 7.2.6 Time Sensor The Time sensor is a function which generates an impuls at an adjustable interval (e.g. every minute, every 5 minutes), thus setting its Boolean output to "1" for a cycles and then back to "0". The following settings are possible fo the Interval parameter: • 1; 2; 5; 10; 15; 30 Seconds, • 1; 2; 5; 10; 15; 30 Minutes, • 1; 2; 6; 12; 24 Hours. The output impulse is thereby always accomplished in synchronized fashion with the time of day.
Condition Monitoring Unit CMU 1000 Page 84 7.2.8 Error Event An error handling can be implemented with the function Error event. The Boolean output is switched to "1" in the event that an error condition is present. The output is switched back to "0" if the error goes away. The type of error event can be set with the Event parameter.
Condition Monitoring Unit CMU 1000 Page 85 Additional points for sequency controls in the CMU The two interrelated function components Sequency and Transition can be used to implement the functionality of sequency controls or finite state machines. 7.2.11 Sequency The Sequency component has a numerical output. This represents the current state of the sequency. At the same time, a number is allocated to all states. The term 'sequency' has been taken from control engineering.
Condition Monitoring Unit CMU 1000 Page 86 7.3 Numerical Calculations 7.3.1 Addition The Addition function returns the sum of the two input values at the output: y = x1 + x2 Inputs Outputs: Parameters: x1: x2: y: - (Numerical) (Numerical) (Numerical) 7.3.2 Subtraction The Subtraction function returns the difference between the two input values at the output: y = x1 - x2 Inputs Outputs: Parameters: x1: x2: y: - (Numerical) (Numerical) (Numerical) 7.3.
Condition Monitoring Unit CMU 1000 Page 87 7.3.5 Division Remainder The Division remainder function returns the division remainder of the two input values at the output (the modulo). The division remainder is determined by performing a whole number division x1 / x2 and outputting the remainder of this division as output value. If the input x1 counts upward, e.g. sequentially by 1, and the input x2 amounts to 5, the the output will count around from 0 to 4.
Condition Monitoring Unit CMU 1000 Page 88 7.3.9 Raising to a Higher Power The Raising to a higher power function supplies the power of the input value at the output. The exponent is set with the Exponent parameter. Inputs: Outputs: Parameters: x: y: p1: (Numerical) (Numerical) Exponent (Numerical) 7.3.10 Square Root The Square root function supplies the square root of the input value at the output.
Condition Monitoring Unit CMU 1000 Page 89 7.3.13 Decade Logarithm The Decade logarithm function supplies the logarithm of the input value at base 10 at the output. If the input value is negative or 0, then the value 0 will be supplied at the output and an error flag will be set. One can react to this situation with the Error event function (see Chap. 7.2.8).
Condition Monitoring Unit CMU 1000 Page 90 7.3.15 Differential Quotient The Differential quotient function supplies the derivation of the input value over time at the output. The output is always calculated with the unit of seconds. This means that an increase of the input value from 5 to 6 in one second will yield an output value of 1. The differential quotient is formed and filtered numerically by the differential quotient.
Condition Monitoring Unit CMU 1000 Page 91 7.4 Numerical Operations 7.4.1 Minimum The Minimum function supplies the smaller of the two input values at the output. Inputs: Outputs: Parameters: x1: x2: y: - (Numerical) (Numerical) (Numerical) 7.4.2 Maximum The Maximum function supplies the larger of the two input values at the output.

Condition Monitoring Unit CMU 1000 Page 92 7.4.5 Median Value The Median value funtion supplies the arithmetical median value of the input values over an adjustable time range. The time range is set in seconds with the Time parameter. The formation of the median value is accomplished by means of the "Repeating Average" procedure. This means that, when the time setting is "2 seconds", for example, the input values are compiled for 2 seconds, then averaged and output at the output.
Condition Monitoring Unit CMU 1000 Page 93 7.4.8 Note Maximum The Note maximum function supplies as the output value the largest value that the input value has yet reached. If the input value is less than the output value, then the output value remains unchanged. If the input value is greater, then the output value will be reset. The maximum can be reset with the Boolean input x2. The input value will be applied directly at the output for as long as this input is "1".
Condition Monitoring Unit CMU 1000 Page 94 7.4.10 Tabular Index The Tabular index function is the counterpart to the Tabular value function. The input value is sorted into a parameterizable numerical table, which must be organized in order of increasing values, and the number of the tabular entry is output. If, for example, the first tabular entry is 4 and the second is 7.8, then a 0 will be output for all input values less than 0, the value 1 will be output for all values between 4 and 7.
Condition Monitoring Unit CMU 1000 Page 95 7.4.12 Slope The Slope function is used to prevent rapid value changes. Under stable conditions, the input value is shown at the output. Changes of the input value are however not passed along directly to the output, but rather only in small steps. Like a slope, so to speak. Different slopes can be defined thereby for positive and negative value modifications.
Condition Monitoring Unit CMU 1000 Page 96 7.5 Counting Functions 7.5.1 Count Pulses The Count pulses function has three Boolean inputs and one numerical output. If the Counting input has the value "1", then the change from "0" to "1" at the Pulses input will be counted and the count value will be set at the output. If the Reset input is at "1", then the count value, and thus the output as well, will be "0".
Condition Monitoring Unit CMU 1000 Page 97 7.6 Numerical Conditions 7.6.1 Equals The Equals function compares two numerical input values for equivalence and outputs a "1" at its Boolean output if the values are equivalent, otherwise a "0". With the Precision parameter, you can adjust how precise the comparison is. For this the following explanation: In view of the fact that numerical values are presented on computers as floating point numbers with finite precision, normal comparisons usually fail.
Condition Monitoring Unit CMU 1000 Page 98 7.6.3 Greater than The Greater than function compares two numerical input values for equivalence and outputs a "1" at its Boolean output if value x1 is greater than x2, otherwise a "0". In view of the fact that numerical values are presented on computers as floating point numbers with finite precision, it is difficult to make decisions in border ranges. (See the explanation in Chapter 7.6.1, Equals function).
Condition Monitoring Unit CMU 1000 Page 99 7.6.6 Less than or Equal to The Less than or equal to function compares two numerical input values for equivalence and outputs a "1" at its Boolean output if value x1 is less than or equal to x2, otherwise a "0". For more on the subject of precision, please note the explanations in the Greater than function (see Chapter 7.6.3). Inputs: Outputs: Parameters: x1: x2: y: - (Numerical) (Numerical) (Boolean) 7.6.
Condition Monitoring Unit CMU 1000 Page 100 7.7 Boolean Links 7.7.1 Not The Not function supplies the negated Boolean input value at its Boolean output. I x = "0", then a "1" is output, otherwise a "0". Inputs: Outputs: Parameters: x: y: - (Boolean) (Boolean) 7.7.2 And The And function links the two Boolean inputs with the "and" operation and supplies the result to its Boolean output. The output is then "1" only if both inputs are "1", otherwise it is "0".
Condition Monitoring Unit CMU 1000 Page 101 7.7.4 Or The Or function links the two Boolean inputs with the "or" operation and supplies the result to its Boolean output. The output is "1" if one of the two inputs is "1". If both are "0", then the output will also be "0". The following log table makes this function clear. x1 x2 y 0 0 0 0 1 1 1 0 1 1 1 1 Inputs: Outputs: Parameters: x1: x2: y: - (Boolean) (Boolean) (Boolean) 7.7.
Condition Monitoring Unit CMU 1000 Page 102 7.7.6 Exclusive Or The Exclusive Or function links the two Boolean inputs with the "xor" operation and supplies the result to its Boolean output. The output is "1" if precisely one of the two inputs is "1". If both of the inputs are "0" or if both of the inputs are "1", then the output will be "0". One can also say that the output is then precisely "1" if the two inputs are not equivalent. The following log table makes this function clear.
Condition Monitoring Unit CMU 1000 Page 103 7.8 Other Boolean Operations 7.8.1 Note Value The Note value function is used to hold on to a Boolean value (to freeze it). It has two Boolean inputs. If the input value x2 is "1", then the input value x1 is output at the output. If the input value x2 is "0", then the last output value remains in effect. If the value is only to be applied for one flank, then you can put the function Pulse generation upstream at x2 (see Chap. 7.8.6).
Condition Monitoring Unit CMU 1000 Page 104 7.8.3 T - Flipflop The T-FlipFlop function is the representation of a surge relay. The output switches over every time Boolean input value changes from "0" to "1". (Toggle function, which is the reason for the name TFlipflop). A side effect of the T-FlipFlop is that is reduces the frequency of a counting signal down to half its size. The output is set to 0 after initialization at the time of program start.
Condition Monitoring Unit CMU 1000 Page 105 7.8.5 RS - Flipflop The RS-FlipFlop function has a Boolean input Set for the purpose of setting the output to "1" and a Boolean input Reset for setting the output back to "0". The Priority parameter can be used to define how the output will react when a "1" is present at both inputs simultaneously.
Condition Monitoring Unit CMU 1000 Page 106 7.9 Result Values 7.9.1 Numerical Output Value The Numerical output value function makes a numerical input value available to the outside. It publicizes the value. Output values are displayed on the CMU as well as in the measured value display on a connected PC. Furthermore, the output values are also recorded in the log recording (see Chap. 7.10.3). A maximum of 32 values can be publicized.
