3 Operation
This section provides information for using the temperature transmitter.
3.1 Setting Parameters
These options are available when setting parameter values using IO-Link.
• Reading current process values.
• Reading, changing and saving current parameter settings and transmitting them to
other units of the same type.
• Read saved diagnostic information (see Troubleshooting ).
Note
To configure the temperature transmitter, connect the temperature transmitter to a PC
using the IO-Link interface. For more information, go to

3.1.1 Adjustable parameters
This table describes parameters that can be modified.
Parameter Description
Uni Sets the standard unit of measurement: °F or °C .
OU2 Configuration of the analog signal: I = 4-20 mA or Ineg = 20-4 mA
ASP Analog start point for measured temperature value
AEP Analog end point for measured temperature value
drW Drift warning threshold. If the temperature measurement exceeds the
deviation value, the temperature transmitter sends a warning diagnostic
message when drEd is set to OFF.
• °F/°C: Maximum permitted temperature deviation of both sensor elements
from the average value.
• OFF: Drift warning deactivated.
drA Drift alarm threshold. If the temperature measurement exceeds the deviation
value, the temperature transmitter sends an alarm diagnostic message when
drEd is set to ONdr or OFF.
• °F/°C: Maximum permitted temperature deviation of both sensor elements
from the average value.
• OFF: Drift alarm deactivated.
