GreaterThanEqual Function Block
The Greater Than Equal function compares two inputs. The block outputs "true" when the In A is greater than or equal to the In B; otherwise, it outputs "false".
Figure 1: GreaterThanEqual - Function Block |
Figure 2: GreaterThanEqual - Property Sheet |
The output is set to "true", if In A > = In B.
The output does not change or "false", if In A = < (InB - Hyst).

Description |
In A |
This is a 32-bit floating point input slot. |
In B (In & Par) |
This is a 32-bit floating point input slots. |
This hysteresis value is defined inorder to avoid cycling Output. |

Parameters
Parameter Name |
Description |
In B Par (In & Par) |
If In B is "null", then In B Par is used. |
Hyst Par (In & Par) |
If Hyst is "null", then Hyst Par is used. |
Out Save |
Master Sync Enabled : If you set it to "true" the last output will be set as output for one cycle after the controller restarts. The application can use it to return to the same state before the controller restart. Out: To enable or disable the Out feature. |
Examples
If the In A >= In B Out is set to "true". Hystersis may be defined.
