Comparison value 0
Operating mode "Use position value (SSI absolute value) as reference"
With the parameter assignment of the comparison value (Page 48), you specify the position
value at which the digital output DQ0 switches as a result of the selected comparison event.
You must enter a positive integer (DINT) that is less than comparison value 1. The default
setting is "0".
Operating mode "Use measured value as reference"
With the parameter assignment of the comparison value (Page 52), you specify the
measured value at which the digital output DQ0 switches as a result of the selected
comparison event.
You must enter a floating point number (REAL) that is less than comparison value 1. The
minimum value is -7.922816 x 10
value depends on the measured variable.
Comparison value 1
Operating mode "Use position value (SSI absolute value) as reference"
With the parameter assignment of the comparison value (Page 48), you specify the position
value at which the digital output DQ1 switches as a result of the selected comparison event.
You must enter an integer (DINT) that is greater than comparison value 0 and less than or
equal to the high counting limit (maximum position value) The default setting is "10".
Operating mode "Use measured value as reference"
With the parameter assignment of the comparison value (Page 52), you specify the
measured value at which the digital output DQ1 switches as a result of the selected
comparison event.
You must enter a floating point number (REAL) that is greater than comparison value 0. The
maximum value is 7.922816 x 10
value depends on the measured variable.
