Input (X1, X2)
Select input signals used for the operating function. For Square root, Power, Analog accumulation, Peak hold, NOT,
First order lag, only X1 is selectable.
To use last sampled or computed data in an equation, choose tags with asterisk (*).
Caution !
The tag name list shows only those ‘enabled’ in the common setting.
Caution !
Be careful to choose a pen of Not Itself. For example, you cannot choose Function Pen 1 or the last data of Func-
tion Pen 1 to be used as X1 or X2 in an equation for Function Pen 1. When assigning ‘last’ data sample to X1 or X2,
specify also the initial value. Otherwise no data is recorded for the first operating cycle.
Coefficient (K), Constant (A)
For AND, OR, NOT, XOR functions, no coefficient or constant is selectable.
Coefficients, Constants
Max. 6 digits including a decimal point and minus sign
Initial value
Initial value is used in the function operation cycle as default data sample when ‘last’ data is specified in an equation.
If you do not need, leave the field blank.
For Peak hold, First order lag, Moving average and F value calculation, the initial value is not available.
Initial value (analog)
Max. 6 digits including a decimal point and minus sign
Initial value (discrete)
1 for ON, 0 for OFF
Caution !
For an analog signal, ‘e‘ can be used to input an exponential value such as ‘1e9.’ Entering ‘e’ in any other way (e.g.
‘1ee’) will not be recognized as a numeral.
For Logic functions, any setting other than 0 and 1 will be handled as 0 as initial value. For the XOR function, setting
other than 0 and 1 to X1 or X2 will result in ‘0.’
