ESSENTIAL COMPLIANCE INFORMATION
(1). In the CPS MODBUS protocol, implementations should leave unused or
unsupported data points set to the “Not Implemented” value specified in the model
mapping. The Not Implemented value for different data type has different value, here are
the defined:
Not Implemented for a int8 is 0x80.
Not Implemented for a uint8 is 0xFF.
Not Implemented for a int16 is 0x8000.
Not Implemented for a uint16 is 0xFFFF.
Not Implemented for a int32 is 0x80000000.
Not Implemented for a uint32 is 0xFFFFFFFF.
Not Implemented for a string is 0x00.
(2). CPS Units：Units and Scale Factors are defined by CPS Units. As an
alternative to floating point format, values are represented by integer values with a signed
scale factor applied. For example:
Start

Content Description
s
Grid voltage Uab
The Uab unit is V, if current real-time value is Uab=389.5V, the value Uab in register 0x001F is
3895 decimal (0x0F37 hex). So 0.1V indicates that the Uint is V, and Scale factor was Magnified 10
times, so real-time value is 3895/10=389.5
(3).Scale Factor：As an alternative to floating point format, values are represented
by integer values with a signed scaled factor applied. The scale factor explicitly shifts the
decimal point to the left (negative value) or the right (positive value). Scale factors had
been fixed and specified in the documentation of a value. Scale factor signed
range:-10----10. For example

Grid voltage Uab
The Uab unit is V, if current real-time value is Uab=389.5V, the value Uab in register 0x001F is
3895 decimal (0x0F37 hex).Scale Factor is -1, it explicitly shifts the decimal point to the left one bit, then
real-time value is 389.5,
（4）Data Encoding
The MODBUS specification is not explicit on how to encode numbers other than 16-bit integers.
Differences do exist between one manufacturer’s implementation and another’s.
32-bit intege Value
Values are stored in big-endian order per the MODBUS specification and consist of a single
register.

String Value
Store variable length string values in a fixed size register range using a NULL(0 value)to terminate
or pad the string. For example, up to 14 characters can be stored in 7 contiguous registers as follows:

8 Inverter Fault Code Descriptor
When one bit is set to "1", it indicates that the representative of the fault is
occurring, and if the bit is set to "0", it indicates that the representative of the
fault has not occurred.
