The OPC Foundation (OPCF) and the FieldComm Group (FCG) are pleased to announce a collaboration to drive multi-vendor interoperability of instrumentation devices based on OPC UA and the extensions for the field level, named OPC UA FX (Field eXchange). This development will incorporate preliminary work by both organizations. This will ensure that the market will have only one single standard. The aim is to provide an interoperable interface between PLC / DCS and instrumentation devices, such as transmitters, instruments, and actuators. The solution shall support different industries such as oil & gas, pharmaceuticals, chemicals, energy, water & wastewater, and pulp & paper.
To begin this work, a new OPC UA Instrumentation Working Group is being hosted by the OPC Foundation, under the leadership of the Field Level Communications (FLC) Initiative. Participation in the working group is open to members of the OPC Foundation, as well as corporate entity members of the FieldComm Group. Many well-known manufacturers in the process and factory automation industries are represented within this working group to ensure a uniform, worldwide, and coordinated standard for OPC UA-based instrumentation devices.
为了实现仪器设备的供应商间互操作性，工作组将添加到UAFX基础规范中的界面和行为的定义，这是仪器设备的典型特征，包括：
• commonly used interfaces and data types for the industries mentioned above including functional safety,
•特定于仪器设备的诊断信息，
•仪器设备的操作模式，
•在适当的情况下，用于仪器特定功能的状态机和定时模型。
新的仪器设备配置文件规范将使用PubSub，并且可以与不同的基础通信协议（例如UDP/IP）和物理层（例如以太网-APL）结合使用，以支持离散和过程制造中的所有相关用例，包括基于安全仪器，基于安全仪器在适当的情况下，基于以太网时间敏感网络（TSN）的OPC UA安全性和确定性数据交换。
仪器方面应与共同拥有的OPC 30081 / FCG TS10098互补，“工艺自动化设备（PA-DIM）的OPC UA”和其他配套规格。工作组还将努力管理与已经发布或正在开发的其他信息模型重叠。示例包括“校准”模型（协调子组）和“实验室和分析设备”（LADS工作组）。
FCG主席Thoralf Schulz（ABB）说：“ OPC基金会和FieldComm Group在仪器工作组中联合起来是一个重要的里程碑。该协作统一了以前在每个组织中正在进行的单独志愿者计划，并为广泛接受的单一标准创造了基础。它将在支持现有设备技术及其安装到未来的过渡时协调设备集成。结合基于外国直接投资的设备管理和高级物理层（APL），用于低层连接，这是朝着统一的数据交换基础架构的主要里程碑，这将使流程自动化的用户以及过程自动化产品的供应商都受益和解决方案。”
Thomas Hahn (Siemens), Vice President OPCF says: “Digitization needs interoperability. Interoperability needs standards. Extending the OPC UA framework to include an information model for instrumentation devices is important to ensure cross-vendor interoperability and common semantics. No single organization can achieve this alone! Therefore, cross-organizational collaboration is essential – from process automation to discrete manufacturing, from customer to provider, from machine tool builder to solution partners, and so on. Through this collaboration, an important step towards meeting the needs of our customers and the industry is achieved.”
“Extending the OPC UA Framework with an information model for instrumentation devices is important to ensure – in combination with OPC UA Safety, Deterministic Communication, Motion and Ethernet-APL/SPE – cross-vendor interoperability and common semantics, not only for the Controller-to-Controller and Controller-to-Device use cases in Factory and Process Automation, but also supporting OPC UA as a fully scalable technology from the sensor across all levels to MES / ERP and also to the cloud,” stated Peter Lutz, Director FLC Initiative at OPC Foundation.
