System of lines over which data are transferred electronically in parallel or serially.
Intrinsic coherence of data in respect of timing and logical aspects.
Correspondence of data with the reality that they describe.
Output for checking the validity of data.
Direct current (not alternating)
DC [=] (Counter)
DC [=] Direct current
Can be programmed in electronic counters
Device that filters the original information out of an altered signal again.
DeviceNet - conformity and interoperability
Confirmation of agreement of a bus node with the DeviceNet specifications and correct interoperability with other DeviceNet nodes.
See count input
Differential line driver
Output circuit in which the difference between the two signals A and A is evaluated, thus providing high signal transmission reliability.
Deutsche Industrie Norm (German Industrial Standard)
Direction; see counter advance sense
Control input for determining the data sequence (whether ascending for clockwise or counterclockwise rotation).
Blocking of function (see also inhibit)
A display value is "frozen" during counting (for easier reading during fast counts)
Natural binary code
Duty cycle [ED]
Ratio of pulse length to non-pulse period; at 40 % duty cycle, pulse length is 4/10 and non-pulse period 6/10 of total time (see specifications in technical data).
A function is triggered by a pulse (the pulse edge only is evaluated) at the corresponding dynamic input; the counter continues operation regardless of pulse width.
