IAT

What IAT does

IAT Rudolphi & Rau GmbH (branded as IAT) is a Brandenburg, Germany-based engineering services company founded in December 1998 as a spin-off from the environmental technology division of Honeywell AG. The firm specializes in industrial and environmental automation, delivering planning, project management, SPS (PLC) programming, SCADA visualization, and process control system (PLS/TIA) implementation for enterprise customers in water/wastewater, industrial manufacturing, building automation, and traffic/waterways infrastructure. Services span consulting and concept design through custom software development, commissioning, documentation, and ongoing security management via the IRMA risk-management platform.

Technically, IAT operates as a multi-vendor system integrator with certified status at Siemens (S5/S7, TIA, WinCC, PCS 7), ABB (AC31/AC500), Honeywell (Experion PKS, Plantscape, HC900), Schneider Electric/Wonderware, Phoenix Contact, WAGO, and VIDEC. The company supports more than twenty industrial protocols including Profibus, Profinet, Modbus, Industrial Ethernet, OPC, IEC 60870-5-104, Interbus, and GPRS/UMTS/VPN links, and maintains proprietary in-house software libraries that accelerate large-scale SPS programming. It is currently developing an AI-supported data acquisition and analysis system platform under the Brandenburger Innovationsfachkräfte 2022 funding program, and holds ISO 9001:2015 and ISO 27001:2022 certifications issued by DQS in 2025.

IAT earns revenue through fixed-price and time-and-materials professional-services contracts under non-disclosed project-based pricing, sold directly via its website, phone, email and trade-fair channels. The go-to-market is relationship-driven B2B sales to municipalities, utilities, hospitals, and manufacturers in the Berlin-Brandenburg region (projects documented at Charité Berlin, Energie und Wasser Potsdam, Osthavelländische Trinkwasserversorgung, Wasser- und Abwasserverband Rathenow, BAM Berlin, Gillette Berlin, Infineon/ Rhode & Schwarz, ZF Getriebe Brandenburg, TW Biogas). The firm operated continuously through a 2014 leadership transition from founder Uwe Rudolphi to current Managing Director Jirka Rau, and has logged over 600 projects for 130+ customers under current reference criteria.

Broad incumbents

• Siemens AG: Global industrial-automation leader (SIMATIC, PCS 7, TIA Portal). IAT is a certified Siemens system integrator; Siemens is the dominant incumbent in the German DCS/PLC market that IAT services.
• ABB Ltd. Global automation and electrification group (System 800xA, AC500). IAT is a certified ABB system integrator; ABB is a broad incumbent whose installed base drives demand for IAT's integration and migration services.
• Honeywell International Inc. Global process-automation major (Experion PKS, PlantScape) and the company from whose environmental-technology division IAT was spun off in 1998. IAT is a Honeywell Systemhaus partner; Honeywell is a broad incumbent with deep process-industry penetration in Germany.
• Beckhoff Automation GmbH & Co. KG: German automation vendor offering PC-based control, PLC, and drive technology (TwinCAT). A broader incumbent than IAT — IAT is a Beckhoff-style system integrator; Beckhoff itself is also a hardware/platform OEM with which integrators partner.
• Phoenix Contact GmbH & Co. KG: Major German automation, interconnection, and interface vendor. Listed as one of IAT's software-engineering partners; relevant as a broad incumbent whose products IAT integrates and whose partner program materially shapes IAT's go-to-market.
• Schneider Electric SE: Global industrial-automation and energy-management company (Modicon, Wonderware/AVEVA). IAT is a certified Wonderware/Modicon integrator; Schneider is a broad incumbent whose products anchor a significant share of IAT's protocol and SCADA work.

Emerging players

• MPDV Mikrolab GmbH: German provider of MES (Manufacturing Execution System) software and related industrial IT services for discrete and process manufacturing. Comparable to IAT as a mid-sized German industrial-software specialist serving German Mittelstand manufacturers, though at a different layer of the stack.

Direct peers

• ATS Automation Tooling Systems Inc. Global automation systems integrator delivering custom factory automation. Comparable to IAT in core business model (system integration for industrial customers) but operating at vastly larger scale across multiple geographies.
• COPA-DATA GmbH: Austrian developer of the zenon SCADA software platform used widely in industrial automation. Directly adjacent to IAT's SCADA/process control integration practice — IAT integrates such platforms; COPA-DATA builds the underlying software tooling.
• HAHN Automation GmbH: German-headquartered automation integrator building turnkey assembly and process automation systems across multiple industries. Closely comparable to IAT as a German Mittelstand system integrator executing complex PLC/SCADA projects for industrial customers.
