IO-Link interface: Additional functions (continued)
In IO-Link mode, the absolute measured frequency is
output in the process data field CountValue. As soon as
the frequency monitor is activated, Pin 2 or Pin 4 can – in
SIO mode – be assigned the process value SCS: Count
limit / Speed ok (not during the startup delay, always
normally open, output type remains parameterizable).

7.1.4 Startup delay
If the counter function or frequency measurement is
enabled, a startup delay can also be configured using the
StartupDelay parameter in 0x00B6. The time delay can be
set between 0...255 seconds and begins when the supply
voltage is applied to the sensor. The count function or
frequency measurement begins after this time has elapsed.
During the startup delay, the counter output in SIO mode
is high impedance if the count function is active. If the
frequency monitor is enabled, the counter output in SIO
mode (Pin 4) is switched on. Pin 2 is unaffected by the
startup delay and has its configured function from the
beginning.
While the startup delay time is running, the process data
bits SCS: Count limit / Speed ok, Too Low and Too High in
IO-Link mode are inactive and the process data field
CountValue is 0.

Operating hours counter
There are three operating hours counters available
(Register 0x0057):
– Since lifetime
– Since last maintenance
– Since power-up
The default setting is 0. Only completed hours are
counted. Counter values are lost in applications where
sensors are turned on and off only as needed. Use the
system command Maintenance Reset (value 0xA5) to reset
the operating hours counter Operating Hours
Maintenance. Operating Hours Lifetime cannot be reset.
Operating hours counter, see Diagnostics
parameters on page 21.
Boot cycles counter
A boot cycles counter over the lifetime is available
(0x0058). If the sensor is turned on for at least 10 minutes,
a boot cycle is recorded. Counter values are lost in
applications where sensors are turned on and off only as
needed (< 10 min). The value in Boot Cycles (Lifetime)
cannot be reset.
Boot cycles, see Diagnostics parameters on
page 21.
Object in detection range
By using the out of range process data bit, you can record
whether the object to be detected is too close or too far
from the sensor. This can be used to prevent collisions
between the sensor and an object or to detect when the
object is too far from the sensor.
Additional IO-Link functions
The sensor also provides the following functions for
monitoring and diagnostics:
– Overvoltage/undervoltage detection
– Short-circuit detection
– Current sensor internal temperature
– Sensor internal temperature during lifelong operation
and current operation

commands and events on page 19.
