Message communication uses objects and services to send and receive data.

Executing a service (1) for a CB-EP100 object enables data read (2), parameter
change (3), control input (4), initialization of settings (5) and other operations.

Taking CB Object as an example, one instance is provided for the measuring
instrument connected to the CB-EP100. Reading the attributes corresponding to the
measurement values of a measuring instrument instance using a service makes it
possible to read instance (01H=measuring instrument) measurement values.
