Examples:
A value of 4000hex (only Bit 14 set, all others clear) is interpreted as 0.5 decimal
A value of 2000hex (only Bit 13 set, all others clear) is interpreted as 0.25
decimal
A value of 1000hex (only Bit 12 set, all others clear) is interpreted as 0.125
decimal
... and so on until...
A value of 0001hex (Only Bit 0 set, all others clear) is interpreted as
0.000030517578125
Therefore, the actual data values transmitted may be any combination of the
decimal values for any given bit pattern.
M_ME_NC and M_IT_NA
The monitored measured short floating point and monitored integrated total
points occupy two words with double-word addressing.
For example, if you configured the following points:
The following table describes how these points would be stored in the module:
500
Words 40 and 41 (Double-word address 20)
501
Words 64 and 65 (Double-word address 32)
502
Word 104 and 105 (Double-word address 52)
