Greater Than function compares two inputs with each other. The output is set to "true" if In A > In B.
Figure 1: GreaterThan Function Block |
Figure 2: GreaterThan Function - 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).

Input
Input Name |
Description |
In A |
This value is compared against In B. These are 32-bit floating point input slots. |
In B (In & Par) |
This value is compared against In A. These are 32-bit floating point input slots. |
Hyst (In & Par) |
This hysteresis value is defined inorder to avoid cycling Output. |

Description |
Out |
If In A > In B, Out is "true". If In A < (In B - Hyst), Out is "false". |
Table 2: Output of GreaterThan Function
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 In A > In B Output is set to "true". Hysteresis may be defined.
