Chapter 4 IO-Link Parameters
Alarm Configuration
.Class-A Over Voltage
The alarm configuration parameters allow you to select which alarms are required to be enabled and
monitored in the Observation tab while masking the alarms that are not of interest for this application.
The alarm configuration mirrors the Alarm status word and is readable and writable via the IO-Link
protocol.
ON= Alarm Enabled
OFF= Alarm Disabled

Configuration
.X-axis Warning Limit Allows you to enter a desired vibration threshold manually on each one of the X, Y, or Z axis (if these
values are known).
If thresholds are not known, IO-Link module calculates them by sampling vibration during the
calibration time you entered.
The default and maximum allowable value is 160.0 m/s2
m/s2
.Y-axis Warning Limit
.Z-axis Warning Limit
Calibration Period
Allows you to enter the time in which the IO-Link module gathers vibration samples to compute and
obtain the vibration thresholds per axis. During this time, a value of Calibration in progress is displayed
in the calibration status in the Observation tab. After the elapsed time, the calibration status will
change to Calibration complete. This parameter is read/write.
This parameter can be set in tenths of an hour and the minimum value is 0 and maximum is 48 hours.
The actual calibration time has an accuracy of ±1.5% of its programmed value.
hours
Standard Commands
Start Calibration
The IO-Link module begins the vibration calibration when a start calibration system command (0xA7) is
received via the IO-Link protocol or by clicking Start Calibration on this AOP tab.
Cancel Calibration
The IO-Link module stops the vibration calibration process when it receives the Cancel calibration
system command (0xA8) via the IO-Link protocol or by clicking Cancel Calibration in this AOP tab. If the
IO-Link module was previously calibrated, after cancellation, the status goes to calibration complete
and uses the previous threshold values. It helps protect against unwanted or accidental Start
Calibration commands.
