Communicating Via Modbus

Sealevel SeaI/O and SeaDAC modules are designed to integrate seamlessly into

existing Modbus networks. The supported command set will vary depending on the

SeaI/O model number used. Specialized diagnostic commands and other RTU

specific codes are not supported. An overview of the Modbus specification for both

RTU and TCP connections is covered in detail in the interactive documentation

located on the Sealevel website at:

http://www.sealevel.com/software/SeaMAX/

The official Modbus specification can be found at:

http://www.modbus.org

NOTE:

SeaDAC Lite modules do not currently support Modbus commands.
