Interface converters, device servers, and gateways – From RS-232 to Ethernet

Interface converters, device servers, and gateways – From RS-232 to Ethernet

Interface converters and device servers enable the protocol-transparent conversion of serial interfaces, such as RS-232, RS-422, and RS-485, to other standards, e.g., Ethernet (RJ45). Gateways and protocol converters convert various fieldbus and Ethernet protocols (e.g., PROFIBUS to PROFINET), thus enabling the easy integration of legacy serial devices and fieldbuses into modern Ethernet networks.

Serial device servers: Overview of versions

Serial device servers

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 bar code scanners and printers. All the devices have to be connected to Ethernet. In this case, using a multi-port converter saves not only valuable space in the control cabinet, but also 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 with the wide operating temperature range (-40°C ... +70°C) and approval for hazardous areas
  • Minimal space required in the control cabinet with compact form factors
  • Unauthorized access to the devices is prevented with 256-bit AES encryption and authentication mechanisms
  • Troubleshooting can be performed quickly and easily by the user with the extended diagnostic functions of the serial ports
  • The seamless integration of virtual COM ports by native Windows drivers ensures consistently high performance, especially for multi-port applications
Protocol-transparent serial device servers

Virtual COM port application with PC and serial devices

Protocol-transparent serial device servers

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.

Protocol converters and gateways: Modbus/RTU, RAW, and ASCII to Modbus/TCP and EtherNet/IP™

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

Protocol converters and gateways Modbus/RTU, RAW, and ASCII to Modbus/TCP and EtherNet/IP™

Modules from the GW MODBUS TCP/RTU... series are used to convert Modbus/RTU (or ASCII, serial) to Modbus/TCP. You can configure these high-performance modules 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 bar code 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.

Protocol converters and gateways: Modbus to EtherNet/IP™

Integrate any Modbus devices into the EtherNet/IP™ protocol

Protocol converters and gateways: Modbus to EtherNet/IP™

You can integrate Modbus slaves into the EtherNet/IP™ protocol using modules from the GW EIP/MODBUS… series. This enables you to integrate existing Modbus devices into the widely used Ethernet-based EtherNet/IP™ protocol.

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

High-performance access to HART signals via Ethernet

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

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. With the modular HART Ethernet gateway, you can connect up to 40 devices.

Gateways and proxies: From INTERBUS to PROFINET

Gateways and proxies: From INTERBUS to PROFINET

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 the control system or in the field for series connection.

Gateways and proxies: PROFIsafe communication across network boundaries

Gateways and proxies: PROFIsafe communication across network boundaries

Consistent PROFIsafe communication across network boundaries is a unique feature.

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.

PROFIBUS PA gateway

PROFIBUS PA gateway

PROFIBUS PA gateway

There are five head stations to choose from for various applications. The devices are provided with a PROFIBUS PA address by simply using a DIP switch – no programming is necessary.

Analog and digital I/Os and a digital NAMUR input module are available as extensions. Thumb wheels are then used to easily assign the inputs and outputs of the extension modules.

Serial HART gateway

Serial HART gateway

Serial HART gateway

Depending on the application, serial RS-485- or Ethernet-based access to all the digital data from HART devices is possible.

Conventional serial RS-485 gateways can be used for applications that are not time-critical. Each gateway enables the connection of up to 32 devices. Data exchange is on a serial basis, as communication takes place via just one HART master.

Ethernet HART gateway

Ethernet HART gateway

Ethernet HART gateway

Depending on the application, serial RS-485- or Ethernet-based access to all the digital data from HART devices is possible.

The Ethernet HART gateway provides PROFINET, Modbus TCP/IP, and HART-IP access to 40 devices. Each device connection has its own HART master that enables it to forward HART data as fast as possible via Ethernet.

When using a Modbus TCP/IP network, it is also possible to provide four digital inputs and four digital outputs.
