Expresson Example
• Addition 001+002
(Determines the sum of the measured values of channel 1 and channel 2)
• Subtraction 001–002
(Determines the difference between the measured values of channel 1
and channel 2)
• Multiplication 001*K03
(Multiplies the measured value of channel 1 by constant K03)
• Division 001/K02
(Divides the measured value of channel 1 by constant K02)
Power and Other Operatons
Expresson Example
• Power 001**002
(Determines the measured value of channel 1 to the power of the
measured value of channel 2)
• Square root SQR(002)
(Determines the square root of the measured value of channel 2)
• Absolute value ABS(002)
(Determines the absolute value of the measured value of channel 2)
• Common logarithm LOG(001)
(Determines the common logarithm (log
10
) of the measured value
of channel 1)
• Natural logarithm LN(001)
(Determines the natural logarithm of the measured value of
channel 1)
• Exponent EXP(001)
(Determines e to the power of the measured value of channel 1)
Relatonal Computaton
Expresson Example
002.LT.003
If the measured value of channel 2 is less than the measured value of channel 3, the
computed result is 1. Otherwise, the result is zero.
002.GT.003
If the measured value of channel 2 is greater than the measured value of channel 3, the
computed result is 1. Otherwise, the result is zero.
002.EQ.003
If the measured value of channel 2 is equal to the measured value of channel 3, the
computed result is 1. Otherwise, the result is zero.
002.NE.003
If the measured value of channel 2 is not equal to the measured value of channel 3, the
computed result is 1. Otherwise, the result is zero.
002.GE.003
If the measured value of channel 2 is greater than or equal to the measured value of
channel 3, the computed result is 1. Otherwise, the result is zero.
002.LE.003
If the measured value of channel 2 is less than or equal to the measured value of channel 3,
the computed result is 1. Otherwise, the result is zero.
