C_SE_NA and C_SE_NB
The measured normalized point command uses one word with word-addressing.
For example, if you configured the following points:
The following table describes how these points would be used.
Word 2000 (Word address 2000)
Word 10 (Word address 10. Must match the
configuration of point 400 in M_ME_NA.)
Word 2001 (Word address 2001)
Word 12 (Word address 12. Must match the
configuration of point 401 in M_ME_NA.)
Word 2001 (Word address 2001)
Word 18 (Word address 18. Must match the
configuration of point 402 in M_ME_NA.)
The measured normalized points use a data representation defined by the
protocol specification to represent fractional decimal values. The following table
describes the value for each bit as a reciprocal power of two (2), that is two (2)
raised to the power of a negative exponent ( -1 through -15). Bit 15 is the Sign
Bit.
