Description
Parameter Level 1 and Level 2:
levels to be reached
Range of values for each level:
-10000 to 20000
MaxL:
maximum value that must not be exceeded under any
circumstances.
Range of values: -10000 to 20000
StSp:
Start/Stop offset: value that is added to Offset "B" to
create the start/stop level. If the Start/Stop offset is 0,
then the start/stop level is Offset "B".
Range of values:
0 to 20000
Rate:
acceleration with which level 1, level 2 or Offset is
reached. Steps/seconds are issued.
Range of values:
1 to 10000
A: gain
Range of values:
0 to 10.00
B: offset
Range of values:
-10000 to 10000
p: number of decimals
Range of values:
0, 1, 2, 3
Output AQ Range of values for AQ:
0 to 32767
(Current Level - Offset "B") / Gain "A"
Range of values:
0 to 32767
Note
:
When AQ is displayed in parameter mode or
message mode, it is displayed as a scaled value,
both on the LOGO! Base Module and LOGO!Soft
Comfort (engineering units: current level).
Parameters L1, L2
The analog values for the parameters L1 and L2 can be derived from another already-
programmed function. You can use the actual values of the following functions:
● Analog comparator (Page 188) (actual value Ax – Ay)
● Analog threshold trigger (Page 183) (actual value Ax)
● Analog amplifier (Page 195) (actual value Ax)
● Analog multiplexer (Page 213) (actual value AQ)
● Mathematic instruction (Page 227) (actual value AQ)
