## 3 Overview 

## 3.1 Functionality 

The KUNBUS Gateway is a protocol converter. It allows communication between networks with different protocols. 

_Illustration 1:_ Functionality as a slave 

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. The following gateway components are currently available as slaves: 

- CANopen 

- DeviceNet 

- EtherCAT 

- EtherNet/IP 

- Modbus RTU 

- Modbus TCP 

- POWERLINK 

- PROFIBUS 

- PROFINET 

- Sercos III 

The gateway component for DMX can be operated as a master or slave. 

In addition, you can combine the gateway components with the RevPi Core. 

Gateway Component Serial 

7 / 31 

## 3.2 Scripter 

Product variant "Serial" includes a software component that allows you to set up customer-specific data exchange protocols. If, for example, the gateway component is to communicate in an application with a serial-controlled servomotor, this servomotor expects a preset protocol to be processed in order to receive the actuator values or to return sensor values. With the aid of the Scripter you can load small executable program sequences into the gateway component that are then executed there cyclically. With the appropriate data exchange protocol the gateway component can receive such actuator values and transmit these to the servomotor via the fieldbus. The program sequences required are loaded once into the gateway component in the form of a script and then always executed there cyclically. 

To use the Scripter, you need a jumper with USB interface 

(PR1000101), which is not included in the scope of deliver. 

LG _Illustration 2:_ USB jumper aa ◦Attach the USB adapter to the interconnect port of the gateway components as shown in the figure. Make sure that the mini USB port is facing towards the front of the gateway. 

◦Connect the adapter to a USB port of your PC. The appropriate driver will install itself automatically the first time. 

ð In the device manager you now see a new entry "USB Serial Port" in the connections section (COM & LPT) with the corresponding interface name COMxx. 

If the driver does not install automatically, you can download this at the 

following Internet webpage:

## 4 Installation 

## 4.1 Preparations for Inteference-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. 

The following groups should be routed separately from each other: 

|**Group**|**Line**|
|---|---|
|A|Data and power supply lines for:|
||DC voltage below 60 V|
||AC voltage below 25 V|
|B|Data and power supply lines for:|
||DC voltage between 60 V and 400 V|
||AC voltage between 25 and 400 V|
|C|Power supplylines above 400 V|



- You can route cables of the same group together in cable ducts or bundles. 

- Cables of group A and B: 

   - Route the groups in separate bundles or 

   - in cable ducts at a minimum distance of 10 cm from each other. 

- Cables of group C 

   - Route the groups in separate bundles or 

   - in cable ducts at a minimum distance of 50 cm from the other groups. 

## Shielding 

Shield your cables. This will reduce any unintended electromagnetic interferences. 

Gateway Component Serial 

13 / 31 

## 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. 

- Select the following as a reference value for the cross-section of the potential equalization cable: 

   - 16 mm[2] for potential equalization cables of up to 200 m in length 

   - 25 mm[2] for potential equalization cables of more than 200 m in length 

- Use potential equalization cables made of copper or galvanized steel. 

- Connect potential equalization cables extensively with the earth rail. 

- The smallest surfaces possible should be sandwiched between potential equalization cables and signal cables. 

If the devices of the control system are connected by shielded signal cables that are earthed on both sides, the impedance must be 10% of the shielding impedance.

Gateway Component Serial 

## 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). 

- ◦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.** 

- èMake sure that the ambient temperature in the control cabinet is less than 60 °C. 

- èKeep the ventilation slots unobstructed. These must not be covered by cables etc. 

- èMaintain sufficient distance from other devices. 

_Illustration 6:_ Distances for installation 

- ◦Connect each gateway component individually to functional earth. When doing so, make sure that the power supplies of both gateway components have the same ground. 

- ð Your control cabinet now meets all requirements for installing the gateway. 

Gateway Component Serial 

15 / 31 

## 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 PR100101). 

◦ 

## _Illustration 7:_ 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. 

16 / 31 

Gateway Component Serial 

## 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. 

Gateway Component Serial 

17 / 31 

## 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. Instead, connect the functional earth with low impedance to the potential equalization. You can then dispense with this connection if the shield of the fieldbus cable is connected to the potential equalization with lower impedance when entering the control cabinet. 

## **NOTICE** 

## **Connect each of the two gateway components to the power supply** 

èEnsure in particular that no potential differences occur between the GND pins (2). 

Pin assignment: 

|**Pin**|**Assignment**||||||||
|---|---|---|---|---|---|---|---|---|
|1|24 V for module supply|1|2||3||4||
|2|GND||||||||
|3|Do not connect!||||||||
|4|Functional earth||||||||



## **NOTICE** 

## **Do not connect GND to PE** 

This connection could cause unintended malfunctions. 

18 / 31 

Gateway Component Serial 

## 4.6 Connecting a Gateway to the Fieldbus 

To connect the gateway component to the fieldbus, you need a Phoenix connector. 

The gateway component supports three different interfaces: 

– RS-232 

– RS-422 

– RS-485 

The pin assignment varies depending on the interface used: 

|**Modus**|**Pin 1**|**Pin 2**|**Pin 3**|**Pin 4**|**Pin 5**|**Pin 6**|**Pin 7**|**Pin 8**|

## Setting the type of interface 

Use switch MD (3) to define the type of interface. 

Here, you can select the appropriate interface mode. In addition, you can activate or deactivate a termination resistor and failsafe. 

## Termination resistor 

The termination resistor prevents reflexions from occurring at the end of the connection that could cause errors in the data communication. 

The integrated termination resistor is 120 Ω. 

## **NOTICE** 

**Activate the termination resistor only if the module is the first or last subscriber of the connection.** 

Errors in the data communication may occur if the termination resistor is activated while the module is connected at a central position in the network. 

## Failsafe 

A failsafe stabilizes the data transmission. 

**Tip!:** Activate this function for longer, failure prone connections.

# 5.3 Settings in the memory registers To configure the gateway component, you have to access the register of the memory unit using the configuration software of your fieldbus master. 

# The storage unit is the central component for all functions of the gateway component. It is subdivided into individual Memory Register with a width of 16 bits each. The functionality of the addressing was incorporated from Modbus. The register assignment depends on the application and is not specified by the Modbus specification. A Memory Register according to this specification has a register number between 1 (0x0001) and a maximum of 65536 (0x10000), of which the gateway component only uses a small part, however. The 16-bit values are stored internally in the memory in Little Endian order. This must be taken into account when you access data via the fieldbus interface. You have various access rights to the memory register: – Read/Write: In these memory registers you can perform settings actively. We recommend that you perform the correct settings in all memory registers with this access type. Bear in mind that your settings will first be used by the gateway component after a restart. – Read Only: These memory registers are informative. They display the parameters currently used by the gateway component. Gateway Component Serial 23 / 31

## 5.4 Input and Output Data 

So that both modular gateway components can exchange data with each other, both components have a separate input and output area. 

The input area contains the data received by the second gateway component. 

The output area contains the data that is sent to the second gateway component. 

|**Register**|**Use**|**Access**|**Access**|**Values**|**Perma-**|
|---|---|---|---|---|---|
||||**type**||**nently**|
||||||**stored**|
|1-256|Input data|Read Only|Holding/In-|Values provided by the other|No|
||||put*|gatewaycomponent.||
|1025-1280|Output data|Read/Write|Holding|Values that are delivered to|No|

||||puts|gatewaycomponent.||
|10001-138|Output bits|Read/Write|Coils|-|No|
