Seamless Connectivity

Enhancing plant efficiency with digital field connectivity. Digital communication technologies such as Industrial Ethernet with EtherNet/IP, PROFINET, and Modbus TCP protocols enable state-of-the-art Process Automation.

To enhance plant efficiency, the automation industry embraces specific trends, including Industry 4.0, implementing connected systems, adopting predictive maintenance practices, and integrating the Industrial Internet of Things (IIoT).

To effectively support these trends, process plants require seamless access to device data in the field, along with state-of-the-art network technology. Industrial Ethernet enables state-of-the-art technology for wired digital communication, which has been extensively utilized in various industries for many years. Different Industrial Ethernet protocols are available, depending on the capabilities of the PLCs and the specific use cases.

Schematics of an Ethernet network topology


Ethernet technology is already the standard technology that connects the PLC with the upper-layer systems. Now, Industrial Ethernet enables the same technology at the field level as it fulfills the high requirements of industrial applications. These demanding environments are fundamentally different than at home or in the office. While special connectors and cables protect the physical properties of the connection, Industrial Ethernet protocols such as PROFINET, EtherNet/IP, or Modbus TCP enable failsafe deterministic operation.

GF Piping Systems Ethernet-enabled devices provide two Ethernet ports and an integrated switch that enables both line/daisy chain and star topologies. Our Electric Actuators are available with either cable glands and internal connection of Ethernet cables to the RJ45 plugs or with M12 connectors, which make it easy to connect the device without opening the housing.

Real-time communication with digital communication protocols



Modbus TCP

GF Piping Systems provides various digital connectivity technologies, extending beyond Industrial Ethernet. One such offering is Modbus RTU, a widely recognized protocol utilizing RS-485 physics. This protocol facilitates data transmission to Programmable Logic Controllers (PLCs). By adopting Modbus RTU, users gain access to additional device data, allowing for a reduction in the number of I/O cards in the cabinet. Compatible devices include the 9950 Six-Channel Transmitter, ultrasonic flow meters, and the electric actuator range.

In addition to Modbus RTU, GF Piping Systems supports other digital connectivity technologies, such as HART and AS-I, for select devices.

Remote access via embedded web server

Our updated range of state-of-the-art Electric Actuators can easily be equipped with optional Industrial Ethernet accessory cards, enabling all the benefits of a control valve, including a web server to monitor and control the assembly.

The web server includes valuable data and documentation like:

  • All live values
  • Status + Diagnostics
  • Event logbook
  • Monitoring features (current + cycle time)
  • Firmware updates
  • Download Electric Actuator manual
  • Creation of documentation
  • Adjusting end positions
  • Manual control
