4 Function
Depending on the setting of the IO-Link parameter [CMPT], the unit displays the current frequency in
Hz or the rotational speed in RPM. It generates output signals according to the operating mode and
the parameter setting. In addition, it makes the process data available via IO-Link (in Hz or RPM,
depending on the operating mode).
The unit is designed for half-duplex communication. So the following options are possible:
•
Remote display: reading and displaying the current frequency/speed
•
Remote parameter setting: reading and changing the current parameter setting
•
IO-Link parameter setting: IO Device Description (IODD) (
4.1 Operating modes
The following operating modes are available:
Operating mode 1: HZ_M (default)
Description
Displays the frequency in Hz
Application
Standard applications with frequency measurement in Hz

In operating mode 2, the display of the unit always shows kRPM.
Manual selection of the operating mode:
CMPT ─ indication of the operating mode (
25) and ModE ─ switch point mode (
for OUT2
Selection of the operating mode via IO-Link interface:

Link interface" at
4.2 Application as an IO-Link device
4.2.1 General information
The unit has an IO-Link communication interface which requires an IO-Link capable module (IO-Link
master).
The IO-Link interface allows direct access to the process and diagnostic data and enables setting of
the parameters of the unit during operation.
