Operands

OperandDescription
S1The first operand.
Entries are WORD data registers or constants.
This is the air temperature in Celsius (°C).
This value is 10 times the actual value.
S2The second operand.
Entries are WORD data registers or constants.
This is the wet-bulb temperature in Celsius (°C).
This value is 10 times the actual value.
S3The third operand.
Entries are WORD data registers or constants.
This is the air pressure in millibar (hPa) units.
DThe fourth operand.
Entries are only WORD data registers.
This is where the relative humidity and dew point are stored.
This requires 2 data registers.

Notice

Relative Humidity Storage

The relative humidity is stored in the assigned WORD data register D, and the dew point is stored in the assigned WORD data register D+1.
