Command Supported:
Device Command Description Uses
  Read / Write     


Signal Conditioning:
Option Scaling Notes PLC
NLIN 0-65535 Interprets the value as "Unsigned" then scales to the rawrange. This SC is used for backward compatibility with older systems where Unsigned pollrecs were used with SC=LIN  
PROP user defined Scales user defined raw range entered in the HW-Options field to EGU range (Linear Scaling)

e.g. HW-opt=819:4095 for live zero 12 bit AD converter

ROOT user defined Scales user defined raw range entered in the HW-Options field to EGU range (Scaled porprotional to the square root of the raw range)  
S&M User configurable Shift & mask Shifts the word Right then ANDS the result with the mask. The parameters are stored in the HW-OPTIONS Field in the form SHIFT:MASK

S5 - This is useful for the T and C pollrecs where you would use

0:1023 to strip out the lower 10 bits

iFLT No Scaling Interpret 2 registers as Little Endian Float, same as TFLOAT
