Timer display (ru.43 / ru.44)

ru.43 / ru.44 displays the actual counter reading dependent on the adjusted clock source (LE.21 / 26). By writ-

ing on ru.43 / 44 the counter can be set to a value. If the clock source is changed during the running time the

counter content is maintained but is interpreted according to the new clock source.

Timer reset input selection (LE.19 / LE.24)

Theinputswhichresetthetimercanbedenedwiththefollowingtable. The individual inputs are OR-operated,

i.e.ifoneofthespeciedinputsistriggered,thetimerjumpsbacktozero.Ifastartingandresetconditionare

active simultaneously, reset has priority.
