3.4Inquiry Services

The inquiry services are available only in configuration mode.

3.4.1Inquire 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.
