3.4 Inquiry Services
The inquiry services are available only in configuration mode.
3.4.1 Inquire LSS Address
This service finds the LSS-address of a Slave in configuration mode. Since the LSS
address has four parts (Vendor-ID, Product-Code, Revision-Number and Serial-
Number), four inquiries are required.
Only one LSS slave may be in configuration mode when this service is executed. A
return message contains the LSS sub-address of the Slave in configuration mode, or
returns an error message.
