GET_OPH_INC (auto incremental), 0x31
The GET_OPH_INC function is used to get the service data of the 32
switching channels (hours-run meter and maintenance interval).
The design of the service data is described in section 2.1.1.6.3, „Service Dat".
Before calling this function for the first time, the required address offset must
be set for the hours run or maintenance interval of the appropriate meter using
the SET_ADDR function.
When a new function call is made, 4 bytes are automatically added to the
address offset.
