4.5.6. 06 (0x06) Write Single Register
This function code is used to write a single analog output in an
OME-ET-7000/OME-PET-7000 module. The Request PDU specifies the address of
the register to be written. Registers are addressed starting at zero.
The normal response is an echo of the request, returned after register contents have
been written.
Here is an example of a request to write AO1 of OME-ET-7026/OME-PET-7026 to
55 FF hex:
