Behavior of the Output in Measurement Modes

Introduction
The various ways of setting the behavior of the output are described in this section.
Behavior of the Output in Measuring Modes
You can assign parameters for the digital output of the 1Count24V.
You can store a high and a low limit for frequency measurement, rotational speed
measurement or period measurement. If the limits are violated, digital output DO1 is
activated. These limit values can be assigned and changed with the load function.
You can change the function and the behavior of the digital output during operation. The new
function takes effect immediately. In isochronous mode it always takes effect at time T
You can choose from the following functions:
● Output
● Measured value outside the limits (limit-value monitoring)
● Measured value under the low limit (limit-value monitoring)
● Measured value over the high limit (limit-value monitoring)
Output
If you want to switch the output on or off, you must enable it with the CTRL_DO1 control bit.
You can switch the output on and off with the SET_DO1 control bit.
You can query the status of the output with the STS_DO1 status bit in the feedback
interface.
In isochronous mode, the output is switched at time T
