Info3 Variable type. The authorised types are the following:
•U8: unsigned integer on 8 bits (1 byte)
•U16: unsigned integer on 16 bits (2 bytes, or 1 register)
•U32: unsigned integer on 32 bits (4 bytes, or 2 registers)
•U64: unsigned integer on 64 bits (8 bytes, or 4 registers)
•I8: signed integer on 8 bits (1 byte)
•I16: signed integer on 16 bits (2 bytes, or 1 register)
•I32: signed integer on 32 bits (4 bytes, or 2 registers)
•I64: signed integer on 64 bits (8 bytes, or 4 registers)
•F32: oating on 32 bits (4 bytes, or 2 registers)
•F64: oating on 64 bits (8 bytes, or 4 registers)
•String: the variable is a character string. In that case the “Address_Size”
notation should be used for the “Info2” eld
•Bits: the variable is of the bit eld type. In that case the “Address_1st bit_
Number of bits” notation should be used for the “Info2” eld
•IP: the variable is of the IP V4 address type and is therefore coded on 4 bytes
(2 registers)
•IPV6: the variable is of the IP V6 address type and is therefore coded on 16
bytes (8 registers)
•MAC: the variable is of the MAC address type in “EUI48” format. It is
therefore coded on 6 bytes (3 registers)
Note that the integer types can be modied by adding a sufx. The authorised
modiers are:
•_W: the words are exchanged, i.e. the variable register content is exchanged
in 2 byte blocks
•_B: the bytes are exchanged, i.e. the variable register content is exchanged in
at byte level, one by one
•_WB: the words AND the bytes are exchanged. The 2 previous modiers are
applied.
Thus, for example, the “I32_W” notation indicates that it is a variable of which
bytes 1 and 2 will be exchanged with bytes 3 and 4.
Similarly, the “U16_B” notation indicates that bytes 1 and 2 of the variable are
exchanged. This is a “Little endian/Big endian” conversion.
Info4 Scale Factor: when the variable was generated automatically by SunSpec,
this eld contains the variable name that determines its scale factor when
applicable.
When the congured variable value is calculated, the read variable will have
its decimal point position offset by as many digits as the value of its “scale
factor”.
The formula is var * 10sf” with “var” being the variable value that is read and
“sf” the variable value indicated by the “scale factor”.
For example, for a variable “var1” with scale factor variable “sf var1”.
If “var1” is equal to “1234” and “sf var1” equal to “3”, the decimal point for
“var1” will be offset by 3 digits to the right to obtain “1234000”.
If “var1” is equal to “1234” and “sf var1” equal to “-2”, the decimal point for
“var1” will be offset by 2 digits to the left to obtain “12.34”.
