IMPLEMENTATION
VC10PTC100 (glResistenza, glTemperat, gbError)
Parameters:
| IN/OUT | VARIABLE TYPE | EXAMPLE NAME | DIM | |
|---|---|---|---|---|
| IN | GLOBAL | glResistenza | L | It is the resistance value to be converted in hundredths of Ohms. |
| OUT | GLOBAL | glTemperat | L | It is the converted temperature value expressed in tenths of a Celsiu degrees. |
| OUT | GLOBAL | gbError | B | Variable containing the error code |
Error
Once invoked the function if there are any errors the error variable having the following values:
0 - No error
1 - Value less than the minimum
2 - Value higher than the maximum
3 - Value indicating input disconnected
