6.9.4 Timer and
Counter
Two timers are incorporated in the COMBIVERT. As long as one of the adjustable
starting conditions (LE.18/23) or a programmable input (LE.17/22) is set, the timer
counts until reaching the final range value. If one of the reset conditions (LE.20/25) is
fulfilled or one programmable input (LE19/24) is set, the timer jumps back to zero. The
resolution, whether the timer works in seconds or hours, is adjusted with LE.21/26.
The current timer content is displayed in ru.43/44. On reaching an adjustable comparison
level (LE.0...7), the switching condition 37/38 is set. It can be used to set an output.

Timer / Mode (LE.21/26)
LE.21 and LE.26 determine the clock source and the counting direction of timer 1 and
timer 2. Clock source can be the time counter in 0.01 s or h-raster or impulses from an
input. The timer runs generally as long as a starting condition is active. After a reset
the timer starts again at zero. The timer stops at the maximal value of 655.35. Following
clock sources can be selected:
Bit Value Function
0...2 Clock source
0 Time counter 0,01 s (default)
1 Time counter 0,01 hour
2 Edge counter, each edge increases/decreases the counter by 0.01
3 Edge counter, only positive edges increase/decrease the counter by 0.01
4...7 reserviert
3...5 Counting direction
0 Upward
8 The counting direction is dependent on direction of rotation (FOR=upward;
REV=downward)
16 The counting direction is dependent on direction of rotation (REV=upward;
FOR=downward)
The values from Bit 0...2 and 3...5 are to be added up.
