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.
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 supply lines above 400V
Installation
– 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.
DO0262R00-MGW-UM-DMX-EN
12 / 25
Page 13
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 mm2 for potential equalization cables of up to 200 m in length
– 25 mm2 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.

4.2 Requirements

The Gateway was designed for use in a control cabinet.
NOTICE
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.
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.
Installation
DO0262R00-MGW-UM-DMX-EN
Illustration5: 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.

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).
◦
Installation
Illustration6: Connecting gateway components
ð You can now install the gateway in the control cabinet.
Only ever interconnect 2 gateway components.
NOTICE
If you connect additional components, severe defects could result on all devices.

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. 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.
Installation
NOTICE
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 2 GND 3 Do not connect! 4 Functional earth
Do not connect GND to PE
This connection could cause unintended malfunctions.

5 Configuration

You can operate the gateway component as a master or a slave.
In "Sender" function mode, the gateway component sends data to slaves and performs the function of a bus master (as for a DMX lighting control desk, for example).
In "Receiver" function mode, the gateway component receives data from a bus master and performs the function of an actuator (as for a lighting control, for example).
You have 2 options for configuration of the gateway components:
– Make the setting via the rotary switches
– Making the settings via the partner gateway component

5.1 Supported Size of the Process Data

The gateway component for DMX supports process data up to a length of 512 bytes per direction.
Configuration
NOTICE
Bear in mind that the maximum length of the process data is always determined by the fieldbus with the shorter data length.
Example:
CANopen supports 512 bytes
PROFIBUS supports 244 bytes per direction
In conjunction with PROFIBUS/ CANopen, this means that 488 bytes are transmitted and updated cyclically.
DO0262R00-MGW-UM-DMX-EN 19 / 25

You can set the function mode and the addressing at the rotary switches.
Configuration
DO0262R00-MGW-UM-DMX-EN
Illustration7: Rotary switch
With each rotary switch, you can set a decimal from 0-9. These 3 values together allow you to set a value range of 0-999.
– Switch 0x100 (1) determines the hundreds digit
– Switch 0x10 (2) determines the tens digit
– Switch 0x1 (3) determines the ones digit
Example: You want to set the value 234.
Switch setting:
– Switch 1: 2
– Switch 2: 3
– Switch 3: 4
The values are interpreted accordingly in the following table:

Sender mode
Partner gateway mode
To set a DMX receiver with inactive bus termination at start address 73, you must set the switch as follows:
SW_1 = 0
SW_2 = 7
SW_3 = 3
To set a DMX sender with activated bus termination, which transmits 512 channels, you must set the switch as follows:
SW_1 = 5
SW_2 = 1
SW_3 = 3
To configure via a partner gateway, you must set the switch as follows:
SW_1 = 0
SW_2 = 0
SW_3 = 0
DO0262R00-MGW-UM-DMX-EN 21 / 25
Page 22

5.3 Making the settings via the partner gateway component

You can also make the settings for the DMX gateway component also via a partner gateway component.
In this configuration mode, you as a "sender" can send a maximum 510 bytes, since 2 bytes are required for the configuration.
To make the settings:
◦ Set the rotary switch of the DMX gateway component to "0, 0, 0"
◦ Use the master software to configure the individual bits of the first 2
bytes of the DMX data.
They are assigned as follows:
ByteBit Function Setting options
Configuration
0 0
(LSB) 1 2 3 4 5 6 7
1 0
1 (MSB)

determine the behavior with a communication interruption.
"Sender" function mode
Number of channels to be sent : 1-510 Default value: 510
! Since the first two bytes are occupied by the configura­tion data, a maximum 510 bytes of DMX data can be transmitted in sender mode.
"Receiver" function mode
Receiver address: 1-512 default value: 1
0= inactive Last received data are re­tained
1= active After 1s communication in­terruption, all data bytes are set to 0
1= Receiver
1= Termination inactive
DO0262R00-MGW-UM-DMX-EN

Page 23
Termination
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.
Example:
– Mode
– Sender, Byte 2, do not set Bit 6
– Send data (number)
– Send 73 channels, channels 7310 := 49
– Termination
– Inactive: Byte 2, set Bit 7
– Zero data
– Inactive: Byte 2, do not set Bit 5
