HA20 2-Channel Controller
Memory Floating Point:
NOTE:
Returned as 15 bit 2s complement with +- 5% over/underrange applied..
Therefore this must be considered when scaling values to be displayed at
the Workstation. The following equation may be used to determine a value
for display.
Display Value = MODBUS Value [ (Span Value -Zero Value) 1.1] + {Zero
Value - [(Span Value - Zero Value) .05]} 32767
FP Value Chan 1
FP Value Chan 2
Memory Reals:
NOTE:
Real value represents float value without the decimal point such as 123.4
is returned as 1234. Decimal devisor is returned as 1, 10, 100, or 1000 for
decimal position of 1, 2, 3, or 4, where 123.4 would return the value 10.
