WattNode Modbus Programming Tips

The Modbus.org documents are very broad in scope and cover a variety of topics and applications that most CCS customers need not be concerned with. The following links on this page describe the subset of the Modbus protocol (Modbus RTU) that applies specifically to CCS WattNode® meters in enough detail that a software developer who already has some familiarity with serial communications can quickly implement the Modbus master software needed to communicate with a meter without having to read the entire set of documentation.
