All input and output variables used for programming this function have been declared in the POU
header.
Body
Use ExpansionUnitNumberToIOWordOffset_FP0 (see page 1125) to calculate the word offset of
the analog unit connected to an FP0.
This function block reads the analog input data from the FP0-TC4 (TC8) unit and stores the digital
values in the corresponding ínput channels:
Range
K, J Type
T Type
R Type
8000
Data type
Function
The offset of the first WX/WY address of the RTD unit according
to its position.
FP0R, FP0, FP-Sigma: (use
ExpansionUnitToIOWordOffset_FP0 (see page 1128)) or
unit 1 => address 2, unit 2 => address 4, unit 3 => address 6
FP-X: (use ExpansionUnotToIOWordOffset_FPX_FP0 (see page
1129)) or
INT
input values on the corresponding output channel (0–3 for
FP0-TC4, channel0–7 for FP0-TC8):
Range K, J type (-100,1°C to 500,1°C->-1001 to 5001 or
-148,1°F to 790,1°F -> -1481 to 7901)
Range T type: (-100,1°C to 400,1°C -> -1001 to 4001 or -148,1°F
to 752,1°F -> -1481 to 7521)
Range R type: (0°C to 1500,1°C -> 0 to 15001 or 32°F to
1590,1°F -> 320 to 15901)
