Ethernet connection socket RJ45
Configuration switch
You can set the TCP/IP settings using the software as follows:
IP address under "P-INTERFACES/P-fieldbus/P-PB/PN/Modbus/P-Modbus TCP/IP"
sub net under "P-INTERFACES/P-fieldbus/P-PB/PN/Modbus/P-Modbus TCP/SN"
gateway under "P-INTERFACES/P-fieldbus/P-PB/PN/Modbus/P-Modbus TCP/GW"
If you enter a value of 0-0-0-0 for the IP address, then the following standard values are used, the
IP address is then completed by the hardware:
IP address: 192.168.0.x (x = value at the configuration switch)
Gateway: 0.0.0.0
Subnet: 255.255.255.0
At the configuration switch, the last byte (binary) of the IP address is set. The set IP address in
the example of the diagram on the left is: 192.168.0.42
