4.10. Dual Counter, Two Independent Counters for Encoders 1 and 2:
F07.062 = 10
Both encoder inputs operate fully independent one from the other, with individual scaling,
evaluation and display. Also each counter can be set or reset individually.
Both counters are treated equally, except with recording of minimum and maximum values.
With regard to this function one of the two counters has to be declared as the "main counter".
The unit will record the min/max values of the main counter only and no min/max values will be
available of the other counter.
Attribution of the main counter uses the Multi-Purpose Parameter 1 (F04.030)
F04.030 = 0 :
Encoder 1 represents the main counter (default)
F04.030 = 1 :
Encoder 2 represents the main counter
Presets K1 and K2 are always related to the main counter.
Presets K3 and K4 refer to the other of the two counters
With many applications it may be desirable to toggle the display only between encoder 1 and
encoder 2, without needing to pass over all the other values every time. Therefore the Multi-
Purpose Parameter 2 (F04.031) can be used to choose between one of the following two display
sequences:
F04.031 = 0 :
Standard display sequence with all display values* (default)
Display
L1 (red)
L2 (yellow)
1
Main counter (encoder 1 or encoder 2)
--
--
2
Minimum value of main counter (since last reset)
blinking fast
--
3
Maximum value of main counter (since last reset)
--
blinking fast
4
Counter of encoder 1
blinking slow
--
5
Counter of encoder 2
--
blinking slow
F04.031 = 1 :
Short display sequence to toggle between encoders 1 and 2 only
Display
L1 (red)
L2 (yellow)
1
Counter of encoder 1
blinking slow
--
2
Counter of encoder 2
--
blinking slow
*) Units with analogue output (ZA series) will always generate the analogue signal
from one of the lines 1 to 5, according to assignment by parameter F08.079.
This is also valid when the short display sequence is used.
