Using the MODBUS® Protocol with Omega® CN8200, CN8240, and CN8260 Controllers
■This manual describes the Omega implementation of the MODBUS protocol for the controllers: CN8200, CN8240, and CN8260. The Omega MODBUS implementation enables a MODBUS master to read every configuration parameter, setpoint, and status value stored in the controllers' databases, as well as to write to every configuration parameter and setpoint in the controllers.1 This manual contains information about the MODBUS functions used to read and write these values, as well as the addresses in the MODBUS register map used to read and write values to the controllers' databases.
■Although this manual contains some general information about how the MODBU Sprotocol is used, the focus of this manual is the Omega implementation of the MODBU Sprotocol with controllers. When writing this manual we have assumed that you are familiar with the MODBUS protocol.
■This manual contains tables that list every parameter, setpoint, and status value stored in the controllers and the valid values for each.
■Information about the purpose of every configuration parameter, about the relationships between parameters, and about the effects of setting specific values, is in the (CN8200,CN8240, and CN8260) Controller Configuration and Operation Manual.
■Diagrams that show the terminals to use when wiring the controllers to a MODBU Snetwork are in the installation manual supplied with each Omega controller.
