Use a Calibrating Resistor
1.
Use a calibrating terminal with an integrated calibrating resistor in the
sensor supply line.
2.
In the configuration software, set the measuring input of the I/O
module to 2-wire measurement with Pt100 sensor.
For more information, refer to the software manual for the adapter used.
3.
In the configuration software, set the line resistance to 20 Ω.
4.
Replace the Pt100 sensor at the measuring point with a 100-Ω
measurement resistor.
5.
To measure the resistance, call up the measured value display for the
corresponding measuring point.
6.
Set the displayed value to 0 °C using the calibration potentiometer.
7.
Then reconnect the Pt100 sensor.
EtherNet/IP Connection
The adapter is connected to the Ethernet network using the two Ethernet
interfaces on the front. Mechanically, this occurs through an M12 plug
connection according to IEC 61076-2-101:2012.
Three basic connection scenarios are shown below:
