Query:
An address 0 indicates a broadcast request. All slave stations process a broadcast
request and no response is sent.
The function code is equal to 06.
The register number field is two bytes in length. It may be any value less than the
highest register available in the Micro PLC. It is equal to one less than the number of
the register to be preset.
The data field is two bytes in length and contains the value that the register
specified by the register number field is to be preset to. The first byte in the data
field contains the high order byte of the preset value. The second byte in the data
field contains the low order byte.
Response:
The normal response to a preset single register query is identical to the query.
