    In the Figure 7-3, the status of the User CMD Index = 1 is 0x02. It means that the HART device for the User CMD Index = 1 is disconnected from HRT-710. (In the Figure 7-3, the status of the User CMD Index = 0 is 0x00. It means that the HART device for the User CMD Index = 0 is connected to HRT-710.)
