Service Data
Getting or setting the "up to now accumulated run time and maintenance
interval" is done using the GET_OPH, GET_OPH_INC, SET_OPH and
SET_OPH_INC functions for each channel. The address offset of the relevant
hours-run meter must previously be set using the SET_ADDR function. When
the data is accessed via the GET_CNF_INC or SET_CNF_INC functions, the
address offset is automatically increased by 4 bytes after the read or write
operation is complete. For a write access with SET_CNF and SET_CNF_INC,
the valid password must previously be entered at address offset 0x0310 .
The hours-run meter is stopped in the event of a power failure independent of
the status of the relevant channel.

remains set to zero. The time zone for Germany is 0.
east coast (Eastern Time) for example, an offset of 5 hours (0xFFFFB9B0)
must be entered in the TimeZone. The transition from winter time to
summer time is done using a status bit within the time telegram. By setting
this bit, one more hour will be transmitted by the module. Within the
module, the transition is always performed at 00:00.
