Scaling |
Notes |
| None |
No Scaling |
Ignores EGU range
in the block. No Range checking Alarming. |
| 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) |
| SINT |
No Scaling |
S5 - forces the
value to be interpreted as an signed integer
regardless of the data type of the poll record
(allows you to mix signed & unsigned in one
poll record) S7 -
Resolution depends on the format len. B, W or D
formats
|
| UINT |
No Scaling |
S5 - forces the

regardless of the data type of the poll record

|
| 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

| FLT |
No Scaling |
S5-Use with word
pollrecs to interpret 2 consecutive Words as a
floa S7- Use with 4 bytes
format="D"
|
| LONG |
No Scaling |
S5 - Use with word
pollrecs to interpret 2 consecutive Words as a
Double word |
