Device servers, gateways, and proxies enable the easy integration of legacy serial devices and fieldbuses into modern Ethernet networks. You can also configure and parameterize multiple networks and subsegments consistently. The most common industrial data transmission protocols are supported with various combinations.

Your advantages

  • 1:1 integration of networks or subsegments, thanks to proxy technology
  • Easy system modernization with transparent communication via multiple bus systems
  • Versatile diagnostics: thanks to topology detection and non-proprietary diagnostics concepts
  • Easy scalability, thanks to multiport and modular versions

Connecting bus systems to Ethernet networks

Ethernet-based systems have one major advantage: subsystems can be consistently integrated into the communication and diagnostics concept using interface converters, gateways, and proxies. For example, you can also access field devices via the PROFINET controller. This means that there is no duplicate configuration or addressing. You can therefore also integrate subsegments or older systems without Ethernet into your network. For example, in automotive production a robot cell uses INTERBUS. However, the various control cabinets are networked via PROFINET.

Serial device servers

Various versions of serial device servers as multiport devices  

Serial device server version overview

Serial device servers enable the easy integration of legacy serial devices and buses into modern Ethernet networks.

Many applications involve multiple serial devices in close proximity, such as barcode scanners and printers, that need to be connected to Ethernet. In this case, using a multiport converter saves valuable space in the control cabinet and money.

Furthermore, the application can be customized to allow different users to access different serial interfaces via a single converter.

Your advantages:

  • Embedded web server enables easy startup and configuration
  • Can be used in any industry, thanks to the wide operating temperature range (-40°C ... +70°C) and approval for hazardous areas
  • Minimal space required in the control cabinet, thanks to compact form factors
  • Unauthorized access to the devices is prevented, thanks to 256-bit AES encryption and authentication mechanisms
  • Troubleshooting can be performed quickly and easily by the user, thanks to the extended diagnostic functions of the serial port
  • The seamless integration of virtual COM ports by native Windows drivers guarantees consistently high performance, especially for multiport applications.

Protocol-transparent serial device servers

Free virtual COM port software supplied as standard  

Virtual COM port application with PC and serial devices

The serial device servers from the GW DEVICE SERVER... series are used to connect standard serial devices (usually with RAW or ASCII file formats) to Ethernet networks. The devices can be used as a “virtual COM port” as well as a native TCP or UDP Ethernet device.

Serial device servers with gateway:
Modbus/RTU, RAW, and ASCII to Modbus/TCP and EtherNet/IP™

Easy conversion to industrial protocols  

Integration of any ASCII protocols in Modbus or EtherNet/IP™

Modules from the GW MODBUS TCP/RTU... series are used to convert Modbus/RTU (or ASCII, serial) to Modbus/TCP. These modules are extremely powerful and can be configured for any combination of Modbus client and server.

Modules from the GW MODBUS TCP/ASCII... series can be used to make serial RAW or ASCII strings from devices such as barcode scanners, scales or RFID tags available via the Modbus protocol. You can convert these strings to EtherNet/IP™ using modules from the GW MODBUS EIP/ASCII... series.

Gateway: from HART to HART-IP, Modbus/TCP, and PROFINET

Easy retrofitting for access to HART signals  

High-performance access to HART signals via Ethernet

The modules from the GW PL… series consist of a front module and up to five extension modules. These modules enable the easy parameterization and monitoring of HART field devices via Ethernet networks.

Ethernet is connected via HART-IP, Modbus/TCP or PROFINET. Thanks to the modular HART Ethernet gateway, you can connect up to 40 devices.

Gateways and proxies: from INTERBUS to PROFINET

Proxy for INTERBUS  

Proxy for INTERBUS

Do you want to integrate an INTERBUS application into a PROFINET network? Then the FL NP PND-4TX IB is the ideal solution. Simply parameterize the device using your respective programming tool. Use the integrated switch in the control cabinet as an uplink to control system or in the field for series connection.

Gateways and proxies: PROFIsafe communication across network boundaries

Proxy for PROFIsafe

Unique: consistent PROFIsafe communication across network boundaries.

The PROFIsafe gateway from Phoenix Contact enables secure communication between two PROFINET networks. This means that you can implement non-proprietary functional safety, such as emergency switch-off concepts, across systems.
