Overview 3 Overview 3.1 Functionality The KUNBUS Gateway is a protocol converter. It allows communication between networks with different protocols. Illustration 1: Functionality A Gateway consists of 2 gateway components that master one specific protocol each. You can combine these gateway components as you wish. This design offers you a high degree of flexibility, since you can exchange the individual gateway components at any time.
Overview Features This gateway component enables communication with Ethernet/IP and Modbus TCP. It supports the following functions: – RPI Minimal Requested Packet Interval: 1 ms – ACD (Address Conflict Detection) – DLR You can use the gateway component in a Device Level Ring.

Installation 4 Installation 4.1 Preparations for Trouble-free Operation In the following section we have compiled some general information for you that is important for trouble-free operation. If you are already acquainted with this topic, you can skip to the next section. There, you will learn about which conditions are necessary for installing the gateway. Cable routing Route your cables separately in cable groups. This will protect your gateway from any unintended electromagnetic interferences.
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: – Select an equipotential equalization conductor with low impedance.
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). ◦ Install the DIN rail horizontally in the control cabinet according to the manufacturers' specifications. When doing so, make sure that the Gateway is at a sufficient distance from other devices. NOTICE Your gateway could be damaged if temperatures are too high.
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 provided. Illustration 6: Connecting gateway components ð You can now install the gateway in the control cabinet. NOTICE Only ever interconnect 2 gateway components. If you connect additional components, severe defects could result on all devices. Gateway component for EtherNet_IP 15 / 25 Installation 4.
◦ 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. Gateway component for EtherNet_IP 16 / 25 Installation 4.
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. Instead, connect the functional earth with low impedance to the potential equalization.
To connect the gateway component to EtherNet/IP, you need Two RJ45 connectors. The pin assignment complies with the Ethernet standard. Gateway component for EtherNet_IP 18 / 25 Installation 4.
5.1 Supported Size of the Process Data The gateway component for EtherNet/IP supports process data of a length up to 480 bytes.
Configuration 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 manually: ◦ Set any address between 1-254 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 ◦ Open the website http://192.168.1.
Standard Objects The following objects are available to you for addressing the process data: – Identity Object, Class Code: 01 Hex – Message Router, Class Code: 02 Hex – Assembly Object, Class Code: 04 Hex – Connection Manager Object, Class Code: 06 Hex – TCP/IP Interface Object, Class Code: F5 Hex – Ethernet Link Object, Class Code: F6 hex – Device Level Ring, Class Code: 47 Hex – Quality of Service, Class Code: 48 Hex These objects comply with the ODVA standard.
You can also use these gateway components as a protocol converter for Modbus TCP.
Input Register 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. Register area for bit by bit access (coils) You can also access the input and output data area bit by bit via coils.
