Using the High_Speed_Counter technology object
3.5 Configuring the High_Speed_Counter
Note
You can select the "Between comparison value 0 and 1" and "Not between comparison
value 0 and 1" functions only for digital output DQ1 and only if you have selected the "Use by
user program" function for digital output DQ0.
Comparison value 0(TM Count und TM PosInput)
Operating mode "Use count value as reference"
With the parameter assignment of the comparison value (Page 44), you specify the counter
value at which the digital output DQ0 switches as a result of the selected comparison event.
You must enter an integer (DINT) that is greater than or equal to the low counting limit and
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 0(Compact CPU)
Operating mode "Use count value as reference"
With the parameter assignment of the comparison value (Page 44), you specify the counter
value at which the STS_DQ0 bit is set in the feedback interface. The digital output DQ0 is
not available as a physical output in a Compact CPU.
You must enter an integer (DINT) that is greater than or equal to the low counting limit and
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.
