Fieldbus International

What Fieldbus International does

Fieldbus International AS, operating as Fint, is a Norwegian privately held company founded in 1993 and headquartered at Ullern Alle 28, Oslo, that designs and supplies fieldbus connectivity hardware and embedded protocol software for process automation. The company sells built-in OEM converter boards (T210 Modbus-to-HART, T280 HART adapter, T410 Modbus-to-PROFIBUS PA, T610/T610_B/T610_C to Foundation Fieldbus, T810/T910 WirelessHART) and DIN rail-mounted gateways (T310, T500/T501/T510/T511, T700/T710) that interoperate across HART, WirelessHART, Foundation Fieldbus, PROFIBUS DP/PA, and Modbus RTU/TCP. The product set extends to licensed HART 7.x and ITK-6.x compliant Foundation Fieldbus protocol stacks, starter/development kits (ST21, ST28, ST81), an NB-IoT mezzanine for cloud telemetry, and a patented high-speed fieldbus I/O system for hazardous environments.

Fint serves three primary customer segments: instrument manufacturers and vendors seeking to add multi-protocol fieldbus connectivity to existing transmitters and actuators without full redesign; system integrators integrating legacy Modbus or HART instruments into Foundation Fieldbus or PROFIBUS networks; and plant owners and operators (especially in process industries such as oil & gas, mining, pulp & paper, and power) who need intrinsically safe, certified connectivity and cloud-extensible telemetry for predictive maintenance and asset management. The company is an authorized FieldComm Group "Development Service Provider" and operates its own EMC and temperature testing laboratory, working with DNV Presafe in Oslo on ATEX, CSA, ICEX and IEC hazardous-area certifications.

Commercially, Fieldbus International monetizes through hardware sales (catalog and customized OEM boards/gateways), one-time buyout licensing of embedded HART and Foundation Fieldbus protocol stacks, and professional development and certification services including FDI device package development, DTM-based configuration, and standards training delivered on customer site or in Oslo. Pricing is quote-based with no public disclosure. Distribution combines direct enterprise sales with a network of regional partners/representatives in USA/Canada (Fieldbus Inc., acquired January 2025), Chile/Peru (ETS), Turkey (Emikon Otomasyon), Japan (Nar Planning), and India (Sundar Techno Solutions). The ownership base consists of founder/CEO Halvor Landet, Leiv Eiriksson Nyskapning, Tore Manshaus, Hood Invest, and employees; no private equity, venture capital, or parent company is indicated.
