Function Sequence Tables
Two examples of FST functions are shown below. These functions are executed sequentially.
In the first function, the VAL command writes the current process value (in EUs) of an analog input to
the implied Result Register. The label is used only for identification.
In the second function, when the RR value from Step 0 equals or exceeds the High Alarm value, the
FST branches to the PUMPON function to turn the pump on.
Step 2
Specify FST register values
This step is required only if your FST requires startup floating-point values.
1. Click
Configure > Control > FST Register
. The window shown in Figure 11-3 is displayed.
2. Use the dropdown list to select the FST for which you are defining registers.
3. Enter any required startup values for the FST. Parameters are listed and described in
Table 11-1.
