DEWE-ORION-1616-10x
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-1616-10x 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
separation 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 mea-
surement 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-1616-10x 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.
