PC-based control for
oil and gas production

Intelligent networking improves plant availability in the oil and gas industry

Oil and gas production (upstream) is characterized by distributed production sites, which are typically located either in remote regions with inadequate infrastructure facilities or are installed offshore, which makes them much more difficult to access. Because the production sites operate individual pumping stations that are sometimes several kilometers apart, seamlessly connected controls are essential for efficient system operation. Adding to this problem are pipelines and storage facilities (midstream) that also have to be monitored and maintained.

In terms of the control system, this poses special challenges for the robustness and reliability of the components used. They have to withstand harsh environmental conditions, including extreme temperatures, and must be certified for use in environments with explosion hazards. It is also important for the control system to support modern remote access to monitor process parameters and control the overall plant, which is critical for the profitable operation of offshore plants.

Because of this, the system openness of PC-based control technology comes into play. Owing to the large number of available interfaces in hardware and software, PC-based control enables optimum horizontal and vertical communication among different systems and devices, while permitting easy integration of process control technologies with the cloud. By integrating automation and process technology on one platform using universal software, signals from both hazardous and non-hazardous zones can be processed together. For new plants, explosion protection functions can be directly integrated into the overall control system architecture; for existing plants, the Beckhoff PC-based control platform can simply be expanded to include explosion protection. Beckhoff also supports all common standards in the process industry by embedding interfaces such as NAMUR, HART and FDT/DTM. Measurement modules integrated into the control platform offer a reliable and cost-effective solution for continuous plant monitoring in terms of flow rate, temperature and pressure. The readings collected by the sensors are available in the control system and can be saved in the cloud or on a local server and evaluated for diagnostic purposes. With TwinCAT IoT and TwinCAT Analytics, Beckhoff provides leading-edge software tools for cloud connectivity and data analysis. The widely accepted OPC UA protocol is available on all Beckhoff PC-based controllers, ensuring secure data communication. Therefore, plants can be maintained proactively and on-demand, and downtime can be avoided. This reduces the need for costly on-site support on the part of service engineers and increases the efficiency and availability of production facilities.

EtherCAT Terminals integrate all control functions

Beckhoff uses the principle of PC-based control technology to combine a wide range of I/O components in a single system. For example, EtherCAT Terminals used for integrating functional safety can be freely combined with EtherCAT measurement terminals for precision and high-speed measuring, as well as with I/O modules featuring an integrated safety barrier for connecting intrinsically safe field devices from the hazardous area. These elements can then be integrated into a comprehensive control system, offering plant operators an efficient complete solution for all application-related requirements.

Flexible plant design with PC-based control:

  • integration of all I/O components into a single system
  • combination of safety, measurement technology, and explosion protection
  • openness towards third-party systems
  • high interoperability to simplify retrofits
  • system openness for investment protection

Simplifies the commissioning of field devices: TwinCAT

The full integration of the HART functionality into both the I/O system and the TwinCAT engineering environment ensures simple project planning and commissioning. The HART integration allows users to integrate HART field devices directly into the controller. In addition, TwinCAT reduces engineering effort: The TwinCAT FDT container enables the integration of field device DTMs directly into TwinCAT Engineering and thus offers programming and field device configuration in one environment.

Beckhoff ComDTM enables seamless integration of TwinCAT controllers into existing process control systems. DTMs from the field devices connected to the HART-capable EtherCAT Terminals can be integrated in any desired FDT containers with the help of the ComDTM. This allows field devices to be configured and parameterized remotely in the containers without the need for access to the PLC. Thanks to the comprehensive integration of the HART protocol in TwinCAT, the functions from the Engineering interface can be used.

Integrated controller redundancy increases plant availability

With plant availability playing such a crucial role in the process industry, measures to increase this include using redundant architectures to safeguard against failures of individual control components. For redundant controller operation, TwinCAT Controller Redundancy is available.

The system-integrated software solution allows two standard industrial PCs to be operated as redundant controllers that both run the same PLC program in just a few steps. An additional, high-performance network connection between the two controllers provides the necessary data synchronization, and the fact that standard Ethernet is used means no dedicated hardware components are required. With virtually no effort at all, this ensures that only one of the two industrial PCs addresses the fieldbus components at any given time and that the control programs are executed on both computers with the same database. If one controller fails, the second controller seamlessly takes over, preventing plant downtime and data loss.

Flexible automation components for NOA concepts

NAMUR Open Architecture (NOA) is designed to make data easily and securely available for plant and equipment monitoring and possible optimization without affecting existing automation systems. This is where our modular range of automation components allows us to offer a whole host of flexible solutions.

Many plants feature intelligent field devices that provide further data in addition to the measured value; however, this is often not taken into account, as is the case with HART field devices operated as 4…20 mA sensors, for example. In this case, the device data can be acquired by retrofitting a controller with HART-compatible I/O modules and made available via OPC UA. Depending on the application, the installation of additional sensors for condition monitoring is also useful. Here, the EtherCAT Box modules with an IP67 protection rating can be used. They can be installed directly in the field and thus require no space in the control cabinet.

Ideal for the process industry: The open EtherCAT fieldbus

As a universal and open high-speed fieldbus, EtherCAT is suitable for all areas of application, from PLC and drive technology to sensors, measurement and safety technology, and explosion protection. This means users only need a single communication technology for their entire plant. They can also rely on our in-depth expertise and benefit from the safety and optimal performance of the comprehensive EtherCAT architecture. Besides, the EtherCAT-based control is open with regard to integrating third-party EtherCAT devices and other fieldbus systems.

With its extended distance technology, EtherCAT also simplifies data acquisition across expansive areas by allowing communication over distances of up to 300 m. This can be realized via two EK1101-0010 Couplers which accept standard EtherCAT Terminal blocks. For greater distances, fiber optic solutions with a transmission length of up to 100 km are available. EtherCAT cable redundancy is used to set up a fault-tolerant ring topology to ensure that the network or network segments of a plant are always accessible. Moreover, the EtherCAT diagnostic concept enables comprehensive, complete, and fast error identification. This minimizes downtime, reduces maintenance requirements, and increases the availability of the plant.

Controllers and remote I/Os allow flexible topologies

Powerful Industrial PCs form the basis for a central control station for the management and monitoring of the processes of the entire plant. Sensors and actuators are connected via remote I/Os, which transmit the data from the field to the control station via a fieldbus coupler.

Conversely, with the CX series of embedded PCs, which are certified according to ATEX, IECEx and NEC/CEC for use in zone 2/22, the control of a plant part can run locally in the control cabinet, which opens up potential for more efficient process automation, especially with regard to modularization. In addition, the various functions of TwinCAT automation software are usable directly in the field.

In both cases, the appropriate selection of the controller or coupler can ensure communication to the higher-level system via the required protocol.

Module automation with TwinCAT MTP

The modularity of process systems is standardized by the Module Type Package concept (MTP). MTP describes individual modules based on various aspects, including their interfaces and the executable services. The information about the module is stored in an MTP file, which is then imported into a higher-level control, which enables efficient commissioning and linking of modules from different manufacturers. The integration of the MTP concept into TwinCAT simplifies the guideline-compliant automation of a plant module through automatically generated source code and libraries for PLC programming. As a result, a prefabricated project structure is provided in which the user merely programs the process-specific functions of the service states. Subsequently, an MTP containing the module description can be exported directly from the TwinCAT project.

Benefits of TwinCAT MTP:

  • generates and exports MTP automatically
  • highly customizable for easy adaptation to existing processes
  • standard-compliant IEC 61131 function block library
  • simple MTP/P&ID import
  • seamless integration with TwinCAT Engineering
  • can be combined with TwinCAT XCAD Interface
