The first link above is broken. It is a link to the CR1000X Online Manual -> Communications Protocols -> Modbus.

Many of the dataloggers - such as the CR1000X - can be configured as a Modbus Server. Data can be placed into Registers and Coils during program runtime. Those Registers and Coils can be read from and written to by one or more Modbus Clients, over serial or TCP connections.
