Network connections
There are 2 Industrial Ethernet interfaces on the gateway for connection to an
MQTT broker and for the Industrial Ethernet network with connection to field
devices. The ‘Cloud’ and ‘Device’ network connections. Both connections have
auto-negotiation and crossover detection.
The following table shows the pin allocation with deactivated Crossover detection:

Tab. 7: Network connections
4.2.4.1 MQTT broker
The connection to an MQTT broker is established via the ‘Cloud’ network connec-
tion.
4.2.4.2 Fieldbus protocol and field devices
The ‘Device’ network connection can be used to connect field devices with an
Industrial Ethernet connection directly to the Gateway, e.g. bus nodes or control-
lers (controller, PLC) with protocols such as PROFINET, EtherNet/IP or OPC UA.

Assembly
WARNING
Risk of injury due to electric shock.
• For the electric power supply, use PELV circuits that guarantee a reliable electric
disconnection from the mains network.
• Observe IEC 60204-1/EN 60204-1.
• Connect all circuits for the operating and load voltage supply.
NOTICE
Material damage due to incorrect mounting.
Select screws that are suitable for the material of the interlinking block:
• Polymer: thread-grooving screws
• Metal: screws with metric thread
When ordering a single gateway, all the required screws are included.
The gateway is mounted in an interlinking block of the CPX terminal.
–
Version 1:
Gateway in an interlinking block with system supply, e.g. CPX-GE-EV-S-...
–
Version 2:
Gateway in an interlinking block without system supply between two end
plates with system supply, e.g. CPX-EPL-EV-S-...

1. Check the seal and the seal surfaces.
2. Replace damaged seal.
3. Push the gateway carefully and without tilting into the interlinking block up to
the stop.
4. Screw the screws into the existing thread.
Tighten the screws in crosswise.

General information about installation
WARNING
Risk of injury due to electric shock.
• For the electric power supply, use PELV circuits that guarantee a reliable electric
disconnection from the mains network.
• Observe IEC 60204-1/EN 60204-1.
• Connect all circuits for the operating and load voltage supply.
NOTICE
Short circuit as a result of ingress of liquids or foreign matter.
Damage to the electronics or malfunction.
• Use connection hardware with the required degree of protection.
• Use cover caps to seal unused connections.
• Only operate the product with cover for DIL and rotary switches mounted.
The operating and load voltage supply is via an interlinking block with system
supply or via an end plate with system supply.
Information on power supply:
è
System description of the CPX terminal (CPX-SYS)
è
Pin allocation power supply connection (CPX-PIN-BEL)
Comply with the handling specifications for electro-statically sensitive devices.
NOTICE
Unauthorised Access to the Device Can Cause Damage or Malfunction.
• When connecting the device to a network, protect the network from unauthor-
ised access.
Standards for security in information technology can be used for network
protection measures, e.g. IEC 62443, ISO/IEC 27001.

7.1
Selecting operating mode of the gateway
A gateway operating mode must be selected to establish a connection to an MQTT
broker
Rotary switch for the operating mode.
The rotary switch must be set to [Read only] or [Read/Write] to establish a connec-
tion to the MQTT broker and to the field devices.
7.2
Parameterisation
The gateway is parameterised via the integrated web server of the gateway.
