What Modbus Organization does

The Modbus Organization, Inc. is an independent, member-based 501(c)(6) nonprofit trade association incorporated in Massachusetts that maintains and evolves the Modbus industrial communication protocol suite. Originally introduced by Modicon (now Schneider Electric) in 1979 and transferred to the Organization in April 2004, Modbus is described as the de facto standard in multi-vendor industrial integration with over 7 million nodes deployed across North America and Europe and hundreds of vendors implementing the protocol on thousands of devices. The Organization's technology portfolio spans the Modbus RTU serial specification, the Modbus TCP/IP implementation guide (introduced 1999), the Modbus Security protocol (TLS-encapsulated, port 802, published 2018 with X.509v3 certificate authentication and role-based access control), and the Modbus Serial Line Protocol and Implementation Guide V1.02. Core products are protocol conformance testing services — Modbus TCP/IP Conformance Test ($1,350 member / $1,500 non-member) and MB Serial Conformance Test ($1,440 member / $1,600 non-member) — conducted at authorized test laboratories in the United States, Europe, and Asia.

Revenue is generated primarily through tiered annual membership dues (General Members at $1,500/$2,500/$3,500 depending on employee count; Supporting Members at $500; Individual at $60; Student at $35; Education Institution membership available), conformance testing fees, and sale of the Modbus TCP Developers Toolkit ($500 to Supporting Members, free for General Members). The Organization serves automation device suppliers and manufacturers (primary segment), system integrators, industrial end users across manufacturing, energy, oil and gas, and infrastructure, and students and educators. Distribution is self-serve through the modbus.org website, with specifications and implementation guides available as free downloads under license agreement. Schneider Electric maintains a foundational relationship, hosting multiple board seats including the current President (Todd Snide, to be succeeded by Patrick Lamboley in 2026), and co-owns software/protocol licensing rights through Schneider Automation Inc.

Core offering

The Modbus Organization maintains and evolves the open Modbus communication protocol suite (Modbus RTU, Modbus TCP/IP, and Modbus Security) and operates a membership-based trade association. It provides paid conformance testing services (Modbus TCP/IP and MB Serial) at authorized laboratories to certify device compliance, and offers tiered membership programs (General, Supporting, Individual, Student, Education Institution) with associated technical resources such as the Modbus TCP Developers Toolkit.

Product overview

The Modbus Organization is a standards body and trade association, not a traditional product company. Its offerings consist of protocol conformance testing services (MB Serial Conformance Test and Modbus TCP/IP Conformance Test), freely available specification documents (Modbus Protocol Specification, Modbus Security Protocol, Serial Line and TCP/IP Implementation Guides), and membership programs (General, Supporting, Individual, Student, and Education Institution). General Members receive the free Modbus TCP Developers Toolkit. The organization also maintains a Discussion Forum and Newsletter for community engagement. The portfolio centers on maintaining the Modbus protocol standard, certifying device conformance, and providing educational resources to member companies who implement Modbus in their automation hardware and software products.

Partnerships

Three partnerships are on record, tiered core and minor.

• Schneider ElectriccoreStrategic or Co-development PartnerSchneider Electric (formerly Modicon) introduced the Modbus protocol in 1979 and transferred the protocol to the Modbus Organization in April 2004. Schneider Electric assists the organization and hosts multiple board members including President Todd Snide. The relationship is foundational to the organization's existence and ongoing protocol development.
• Schneider Automation Inc.coreStrategic or Co-development PartnerSchneider Automation Inc. co-owns the software/protocol licensing rights with Modbus Organization. They are listed as manufacturer for U.S. Government restricted rights documentation. Their engineering department must be contacted for reverse engineering permissions.
• SEMI (Semiconductor Equipment and Materials International)minorStrategic or Co-development PartnerIn response to customer demand, the semiconductor industry implemented a Network Communication Standard and Object Messaging Protocol using Modbus TCP/IP, allowing SEMI Sensor Bus compatible sensors to communicate using Modbus TCP/IP. The Object Messaging Specification for Modbus TCP Protocol is used as a component in the SEMI sensor bus Network Communication Standard.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Avnu Alliance: Industry consortium certifying Time-Sensitive Networking (TSN) and Milan audio/video networking devices; an emerging competitor to legacy industrial protocols like Modbus for next-generation deterministic Ethernet deployments in industrial and pro-AV markets.
• HMS Networks: Industrial connectivity products company (Anybus, IXXAT, Ewon) that ships gateways translating between Modbus and virtually every other industrial protocol; it is both a Modbus General Member and an adjacent competitor because its gateways reduce direct Modbus-only device demand.

Direct peers

• OPC Foundation: Independent standards body that maintains the OPC UA industrial communication and information modeling standard; directly competes with Modbus in industrial automation interoperability and offers a contrasting, modern, security-by-design architecture for the same device OEMs and system integrators Modbus serves.
• EtherCAT Technology Group: Vendor-neutral organization maintaining the EtherCAT real-time Ethernet protocol; competes with Modbus in industrial machine control and operates a similar conformance/CETEC-style certification regime funded by member dues.
• CC-Link Partner Association (CLPA): Open trade association promoting CC-Link and CC-Link IE industrial networks; directly comparable as a membership-based standards body with conformance programs targeting factory automation device makers, many of whom also implement Modbus.
• ODVA: Standards organization that owns the Common Industrial Protocol (CIP) and EtherNet/IP, Industrial Protocol (CIP Safety, CIP Motion); directly comparable as a membership-driven industrial networking standards body running CIP conformance testing against Modbus's TCP/Serial conformance testing.
• PROFIBUS & PROFINET International (PI): Trade association governing the PROFINET and PROFIBUS industrial communication protocols; competes head-to-head with Modbus in factory automation, runs its own conformance/certification programs, and operates as a member-funded standards body structured similarly to the Modbus Organization.
• FieldComm Group: Standards body that manages the HART Communication Protocol and FOUNDATION Fieldbus; comparable as a process-automation protocol steward running registered device certification programs and offering membership tiers analogous to Modbus Organization's structure.

Others

• International Society of Automation (ISA): Non-profit professional association setting automation standards (ISA/IEC 62443) and providing conformance/certification programs; thematically adjacent to Modbus Organization as another nonprofit automation steward, though broader in scope and not a direct protocol competitor.
• Object Management Group (OMG): International standards consortium (now part of ISO/IEC JTC 1 work) that develops and curates vendor-neutral specifications including DDS and UML; a peer in operating-model terms (member-funded standards body with conformance programs) rather than direct industrial-protocol competition.
