1.13 MATH Function (/M1 Option)
Overview of the MATH Function
You can enter expressions using constants, operators, and functions described below.
The computed results can be displayed and recorded (saved). MATH allows you to
determine the average/maximum/minimum of a specified channel on a specified date/
time, or output events (start/stop record, reset time, etc.) under specified conditions.
Number of MATH Channels
Computation can be performed on sixty channels, and 240 channels can be used for
communication input. The maximum number of characters that can be used in an
expression is 120 for MATH channels and 8 for communication input channels. Four
arithmetic operations and calculation constants can be written to communication input
channels in addition to the communication input channel number.
MATH Types
The following types of computations can be performed.
• Basic math
• Logical operations
• Relational operations
• Arithmetic functions
• TLOG functions
• CLOG functions
• Conditional expressions
Basic Math
Type Operator Example Explanation
Addition + 001+002 Finds the sum of measured values on channels 001
and 002
Subtraction - 002-001 Finds the difference in the measured values of
channels 001 and 002.
Multiplication * 003*K01 Multiplies the measured data on channel 003 by
constant K01
Division / 004/K02 Divides the measured data on channel 004 by constant
K02
Exponentiation ** 005**006 Raises the measured data of channel 005 to the
power of the measured data of channel 006.
Logical Operations
Type Operator Example Explanation
Logical product AND 001AND002 When channel 001 = 0 and channel 002 = 0, 0
When channel 001 ≠ 0 and channel 002 = 0, 0
When channel 001 = 0 and channel 002 ≠ 0, 0
When channels 001 and 002 ≠ 0, 1
Logical sum OR 001OR002 When channel 001 = 0 and channel 002 = 0, 0
When channel 001 ≠ 0 and channel 002 = 0, 1
When channel 001 = 0 and channel 002 ≠ 0, 1
When channels 001 and 002 ≠ 0, 1
Exclusive OR XOR 001XOR002 When channel 001 = 0 and channel 002 = 0, 0
When channel 001 ≠ 0 and channel 002 = 0, 1
When channel 001 = 0 and channel 002 ≠ 0, 1
When channels 001 and 002 ≠ 0, 0
Logical negation NOT NOT001 When channel 001 = 0, 1
When channel 001 ≠ 0, 0
