In April, the Fieldbus Foundation announced it had挂号的包含新的强制主机配置文件“61B”的前两个基础现场总线主机。现场总线主机由Emerson Process Management（Deltav Digital Automation System，带AMS套件：智能设备管理器）和GE Energy（GE Controlst）通过测试验证其对Namur NE107现场诊断的支持，现在是第二阶段的一部分所需的主机测试和注册。
In the基金会现场总线自动化基础设施, hosts can include configuration tools, recording devices, alarm display panels, human-machine interfaces (HMIs), or a combination of functionality. Host profiles are key to fieldbus system interoperability, as they define required features for different classes of tested and registered hosts. Host profiles include: Class 61 – integrated host, Class 62 – visitor host, Class 63 – bench host non-commissioned device, and Class 64 – bench host commissioned off-line device.
一个概要文件规范提高了组织,integration and presentation of device diagnostics within fieldbus systems. The Foundation fieldbus diagnostic profile includes a standard and open interface for reporting all device alarm conditions, and provides a means of categorizing alert conditions by severity.

以下基础现场总线主机功能从“可选”到“强制”，其中包含新的主机配置文件61B：
- 块实例化 - 允许充分利用支持可实例化功能块的现场总线设备。主要用于控制现场（CIF）。
- 多种能力水平 - 对于某些块/功能是可选的（许可），可以在系统配置期间在标签占位符中设置标准或更高的能力级别，以防止不受支持的块在控制策略中使用不受支持的块。这可以防止在调试期间出现惊喜。它还使设备更换更容易。
- Enhanced function blocks – Allows full utilization of enhanced blocks (standard blocks with additional parameters).
- Profiled custom function blocks– Allows full utilization of non-standard blocks.
- Configuration of scheduled control function locks – Allows developers to build CIF control strategies.
- DD V5.1 device-level access (enhanced electronic device description language [EDDL] with cross-block) – Makes fieldbus devices easier to use by enabling a dashboard with all diagnostics on the same page, and all setup on one page, regardless of which block it is in.
According to Stephen Mitschke, Fieldbus Foundation director of fieldbus products, “support for device-level menus, one of the additional features mandated by host profile 61b, will make it easier for users to configure and maintain fieldbus devices. In addition, registered hosts must now demonstrate the ability to configure field diagnostics in devices.”
Emerson’s chief technology officer, Peter Zornio, commented, “A best-in-class Foundation fieldbus solution is a key part of Emerson’s I/O on Demand offering to our customers, allowing them to choose the best I/O solution for each of their applications. In fact, five out of ten of our largest DeltaV systems on order right now are using Foundation fieldbus technology.”
