Operating time
The operating time monitor stores the operating time for the
device in operating hours. The operating time is saved every six
minutes in the non-volatile memory in the device. This happens
as long as the device is under power. The operating time is
displayed as a 32-bit value without sign in 0.1 h by the
DDLM_Slave_Diag function.If the operating time function is
not supported by the device, it is set to the maximum value
(FFFF FFFF hex).
