5.5.7 Analog comparators
The F650 provides 20 different analog comparators in an analog comparator module located in the control elements part
of the device. Each analog comparator gives indication when the analog variable selected is inside or outside some
minimum and maximum threshold values.
The analog comparator settings includes two global settings such as
Analog Function:
This setting allows enabling or disabling the analog comparators module. Each analog
comparator can not be enabled/disabled individually.
Analog Snapshot Events:
The snapshot event setting enables or disables the snapshot event generation for this element.
Besides the main settings there are some settings for each analog comparator (up to 20) as
follows:
Analog Input:
Analog value selected by the user from the available analog variables in the device. This is
used to make the comparison inside a set band for that magnitude.
Analog Maximum:
Maximum threshold value for the comparison band.
Analog Minimum:
Minimum threshold value for the comparison band.
Analog Delay:
Time value for the analog signal to be active inside the comparison band before setting the
Analog Level signal to 1.
Analog Hysteresis:
It establishes the deadband at each extreme when going out of operation band.
Direction IN: min value = min - hysteresis (in %)
max value = max + hysteresis (in %)
Direction OUT: min value = min + hysteresis (in %)
max value = max - hysteresis (in %)
Analog Direction:
Analog direction for the activation signal to be set Inside or Outside the Deadband.
OUT:
The "Analog Level X" gives an activation signal when the analog value is located outside the
comparison band.
IN:
The "Analog Level X" gives an activation signal when the analog value is located inside the
comparison band.
The F650 provides 20 different analog comparators. Their status values can be viewed at
