Modbus Source Code Libraries

Modbus is an application layer messaging protocol, positioned at level 7 of the OSI model that provides client/server communication between devices connected on different types of buses or networks. Modbus is a request/reply protocol and offers services specified by function codes. Modbus function codes are elements of Modbus request/reply PDUs.

Triangle MicroWorks’ Software Libraries provide a cost-effective means of supporting industry-standard protocols in your device. Incorporating our royalty-free Software Libraries in your products will shorten development time, freeing internal resources to work on company proprietary aspects of your products.

Triangle MicroWorks Software Libraries are available in two formats: .NET Protocol Components for incorporation in Windows .NET-based products, and ANSI-Standard C Source Code Libraries for all other platforms.
