Shielding Shield your cables. This will reduce any unintended electromagnetic interferences. Potential equalization Potential differences occur when devices are connected to different earths. These potential differences cause malfunctions. To prevent malfunctions, you have to route an equipotential equalization conductor. When doing so, bear in mind the following points: –...
4.2 Requirements The Gateway was designed for use in a control cabinet. ü The protection class of the control cabinet must be equivalent to at least IP54. ü For installation in the control cabinet you need a DIN rail 35 x 7.5 mm (EN50022).
4.3 Connecting Gateway Components In order to attain a fully functional gateway, you have to interconnect both gateway components. ◦ Connect an interconnect port to each gateway component using the plug-in jumper (product number PR100204). ◦ Illustration 6: Connecting gateway components ð...
4.4 Installing a Gateway in the Control Cabinet ◦ Hold the raster element of the gateway on the DIN rail. ◦ Press down the locking elements towards the gateway. ◦ Make sure that the gateway is firmly attached to the DIN rail. 16 / 25 Gateway component for EtherNet_IP...
4.5 Connecting a Power Supply To connect the gateway component to the power supply, you need a spring-loaded terminal (e.g. Metz-Connect SP995xxVBNC). You have to connect each gateway component separately to a power supply. Never interconnect functional earth and GND, otherwise the galvanic isolation between gateway GND and fieldbus ground will be removed.
4.6 Connecting a Gateway to the Fieldbus To connect the gateway component to EtherNet/IP, you need Two RJ45 connectors. The pin assignment complies with the Ethernet standard. 18 / 25 Gateway component for EtherNet_IP...

Type Direction Assembly Size Instance Exclusive Owner Output (master -> slave) up to 480 bytes Input (slave -> master) up to 480 bytes Input Only Output (master ->...
5.2 Address Assignment Setting IP Address With the 8-pin address switch you can set the IP address of the Gateways. You can set values in binary format between 0-255. Assigning IP Address ◦ Set any address between 1-254 manually: ð The gateway component uses the address 192.168.1.X with the net mask 255.255.255.0 and gateway 192.168.1.1 ◦...

Siemens controllers use 2 predefined address areas. Therefore, the input and output registers can each be accessed via 2 addresses, one KUNBUS address and one Siemens address. Both addresses address the same memory cell, however. No separate address areas is defined for the input register. Read the holding register with function code 0x04.
