The output is set and reset depending on the difference Ax - Ay and on two configurable
thresholds.
Parameter Parameter Parameter Parameter p p p p (number (number (number (number of of of of decimals) decimals) decimals) decimals)
The on threshold On and the off threshold Off can be provided by the actual value of another
already-programmed function:
Analog comparator: Ax – Ay
Analog trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Analog math: AQ
PI controller:AQ
Data latching relay: AQ
Up/Down counter: Cnt
Applies only to Ax, Ay, Delta, On and Off values displayed in a message text.
Does not apply to the comparison of on and off values! (The compare function ignores the
decimal point.)
The value of
＂

can be set/modified in parameter mode. For
information about how to set/modify, refer to chapter 5.2.2 please.(Dec means decimal point.)

Inputs Ax, Ax, Ax, Ax, Ay Ay Ay Ay Input the analog signals of which you want to
determine the delta at the inputs Ax and Ay.
Use the analog inputs AI1...AI8, the analog outputs
AQ1 and AQ2.
AI1..AI8: 0 - 10 V corresponds with 0 - 1000 (internal
value).
