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 218) (actual value Ax – Ay)
● Analog threshold trigger (Page 213) (actual value Ax)
● Analog amplifier (Page 226) (actual value Ax)
● Analog multiplexer (Page 248) (actual value AQ)
● Mathematic instruction (Page 265) (actual value AQ)
● PI controller (Page 256) (actual value AQ)
● Up/down counter (Page 201) (actual value Cnt)
If your LOGO! is a LOGO! 0BA7, you can additionally use the actual values of the following
functions:
●
Analog filter (0BA7 only) (Page 271) (actual value AQ)
● Average value (0BA7 only) (Page 276) (actual value AQ)
● Max/Min (0BA7 only) (Page 273) (actual value AQ)
● On-delay (Page 160) (current time Ta)
● Off-delay (Page 164) (current time Ta)
● On-/Off-delay (Page 166) (current time Ta)
● Retentive on-delay (Page 168) (current time Ta)
● Wiping relay (pulse output) (Page 170) (current time Ta)
● Edge triggered wiping relay (Page 172) (current time Ta)
● Asynchronous pulse generator (Page 175) (current time Ta)
● Stairway lighting switch (Page 179) (current time Ta)
● Multiple function switch (Page 182) (current time Ta)
● Stopwatch (0BA7 only) (Page 198) (actual value AQ)
● Analog ramp (actual value AQ)
● Threshold trigger (Page 210) (actual value Fre)
