Sign Assignment
This function block can be used to assign different signs to the input value X according to the value at the input I. IF I>=0.0, the value X is multiplied with 1.0, otherwise X is multiplied with -1.0.
Operation
Y = X * 1.0 or Y = X * -1.0
Signals
| Name | I/O | Type(s) | Function |
| X | I | FLOAT | Input value |
| I | I | FLOAT | Indicator for the sign |
| Y | O | FLOAT | Output value |
Comments
This function block can be used to detect the sign of a changeable value and in that way work like a sign function. If the input X has a fixed value and the changeable signal is connected to I, output Y will alternate between +X and –X.
