DEWE-ORION-0824-20x
3.2.2.3 Count Direction
As default setting the count direction is in up-counting mode. Every rising edge at the input will increase the
counter value. The DEWE-ORION-0824-20x supports also down counting without the need of an additional
input like in the up/down counting mode.
3.2.2.4 No new value available
Especially in every kind of input period time measurement mode (also pulse width or two pulse edge separa-
tion measurement) there may be new information between two samples. Also measuring the line frequency
of about 50 Hz with a sample rate of 10 kSamples/sec means, that only after every 200th measurement new
input frequency information is available. Another example is the measurement on rotating machines if the
sensor output frequency is lower than the sample rate. Depending on the application the DEWE-ORION-
0824-20x can choose between two different output data settings:
• Repeat last value: last measured cycle time is taken until a new measured cycle time is available.
• Make zero value: as soon as no input information is available the output is set to Zero.
