Fieldbus

What Fieldbus does

Fieldbus Inc. is a privately held Texas corporation founded in 1993 and headquartered in Austin, Texas, specializing in fieldbus technology solutions for industrial process automation. The firm is one of only three Development Services Providers (DSPs) globally authorized by the FieldComm Group to support FOUNDATION Fieldbus, HART, and WirelessHART communication technologies, and contributes to FieldComm technical teams including the Function Block, ITK, and Application Profile working groups and serves as editor of the Transducer Block Specification.

The company's product portfolio centers on three layers: (1) fully conformance-tested FF-H1 and HART 7.x communication stacks licensed as one-time buyouts in executable, object, or source code form across ARM Cortex-M3/M4, Motorola 68331, and Renesas m16c processors; (2) a family of T-series protocol converter gateways and OEM build-in modules that bridge Modbus, HART, WirelessHART, FOUNDATION Fieldbus, and PROFIBUS networks; and (3) Device Description (DD) design, function block development, starter kits, training/demo devices, and professional services including consulting, compliance testing, and verification. A 2020 product launch extended stack support to ARM Cortex-M3/M4 (STM32) processors.

Fieldbus Inc. generates revenue through four streams: one-time communication stack licensing, hardware sales of gateway and OEM modules, professional services for fieldbus implementation and compliance testing, and starter kit/development tool sales. The firm operates as a sales-led B2B technology provider targeting instrumentation and control suppliers, field device manufacturers, and end-user plants/operations in the process automation industry, with distribution via direct sales, website inquiry, and alliance channels through National Instruments and Fieldbus International (Fint).

Expansion highlights4 records

Direct peers

• Acromag: Acromag designs and manufactures process instrumentation and embedded I/O modules for FOUNDATION Fieldbus, PROFIBUS, and HART networks, including protocol gateways. Comparable as a smaller specialized peer in the fieldbus hardware and embedded module market with similar customer base in process automation.
• HMS Networks: HMS Networks (Anybus, Ixxat, Ewon) sells industrial communication solutions including protocol gateways, embedded communication modules, and protocol stacks for the same multi-protocol environments (PROFIBUS, PROFINET, EtherNet/IP, FOUNDATION Fieldbus, Modbus). Comparable in protocol-conversion gateway business and embedded OEM module offerings to instrumentation vendors.
• Softing Industrial Automation: Softing is a direct peer providing fieldbus and industrial Ethernet communication technology, including protocol stacks, gateways, and diagnostic tools for FOUNDATION Fieldbus, HART, PROFIBUS, and PROFINET. Highly comparable in product category, customer base (device manufacturers and system integrators), and licensing-plus-hardware business model.

Broad incumbents

• Yokogawa Electric: Yokogawa is a major process automation incumbent and FOUNDATION Fieldbus device manufacturer, contributing heavily to the FieldComm Group ecosystem. Comparable as a customer/competitor for fieldbus development services in the process industries where Fieldbus Inc. sells protocol stacks and consulting.
• Siemens Industrial Communication: Siemens offers its own FOUNDATION Fieldbus and PROFIBUS protocol stacks, function blocks, and development tools (often via the SPC42 controller family that Fieldbus Inc.'s ARM stack explicitly supports). Broad incumbent competitor for device manufacturers seeking compliant fieldbus implementations and integration support.
• Phoenix Contact: Phoenix Contact provides industrial communication gateways, protocol converters, and I/O solutions for PROFIBUS, PROFINET, FOUNDATION Fieldbus, and HART environments. Overlaps with Fieldbus Inc. in protocol converter hardware and serves overlapping instrumentation and process automation customers.
• Emerson Automation Solutions: Emerson (formerly Emerson Process Management) is headquartered near Fieldbus Inc. in Austin and is both a major FOUNDATION Fieldbus/HART device manufacturer and a competing provider of device development services, configurators (AMS Device Manager), and valve diagnostics. Broad incumbent in the same ecosystem, with Fieldbus Inc. as a smaller specialized supplier.
• Pepperl+Fuchs: Pepperl+Fuchs is a large incumbent in process automation with a strong FieldConnex portfolio of FOUNDATION Fieldbus infrastructure (power supplies, gateways, segment protectors) and HART solutions. Overlaps with Fieldbus Inc. in fieldbus hardware and infrastructure for process industry customers, but operates at significantly greater scale and breadth.

Emerging players

• Moore Industries: Moore Industries offers HART and FOUNDATION Fieldbus interface solutions, protocol gateways, and signal conditioners for process industries. Comparable as a smaller specialized player in fieldbus/HART hardware and integration products targeting the same instrumentation and control customer base as Fieldbus Inc.
• R. STAHL: R. STAHL provides explosion-protected FOUNDATION Fieldbus and PROFIBUS PA infrastructure (Remote I/O, gateways, segment protectors) for hazardous process environments. Comparable in fieldbus hardware for oil and gas / chemical applications and overlaps in serving device manufacturers needing intrinsically safe fieldbus solutions.
