About Modbus
The Modbus Organization is a group of independent users and suppliers of automation devices. We seek to drive the adoption of the Modbus communication protocol suite and the evolution to address architectures for distributed automation systems across multiple market segments. The Modbus Organization will also provide the infrastructure to obtain and share information about the protocols, their application and certification to simplify implementation by users resulting in reduced costs.
A community for the Modbus communications protocol - data communication between devices over TCP/IP and over serial line – open and royalty-free since 1979. Visit Modbus.org to download the Modbus protocol specification and implementation guides.
