53HC2600 INSTRUCTION MANUAL
Online Configurations 39
The dialog title shows the tagname, and the function block mnemonic found in the Micro-Mite controller.
This dialog is laid out to show signal flow through the analog input block, starting at the screw on the left,
flowing through the AI1 block, and producing the analog value.
4.4.4.1 Changing the AI Input Base Online
Setup the AI1 function block for a 0-20 mA input source:
1. Click on the Base button. The picture inside the button, and the text below the button, change
between 0-20 mA and 4-20 mA configurations.
2. Change the input base to 0-20 mA. The AI1 Base parameter changed as soon as you clicked
its button.
Notice the Cancel button changed to Close because the controller database changed while
this dialog was open.
3. Try clicking on the Lin/SqRt button. The picture inside and the text below the button change
between Linear and SqRoot.
4. Set it back to Linear.
4.4.4.2 Changing the AI Digital Filtering Online
The Micro-Mite controller AI blocks are capable of smoothing input noise with a digital filter. Apply a small
amount of filtering by setting the digital filter to 1.5 seconds:
1. Click on the Digital Filter button and the Digital Filter dialog pops up.
2. Click on the down arrow to drop down the list of selections. Use the scroll bar to see other
entries in the list. Select 1.5 s.
3. Click OK to close this dialog and change the Digital Filter setting.
4.4.4.3 Documenter Supplementary Information
Since this is an online configuration, additional information regarding the input transmitter type cannot be
stored for the Documenter Report; therefore, the selection Doc Info... appears as a graytone in the dialog
box. (To add this information, the online configuration must first be uploaded and saved as an offline .S6D
file, then added in offline operation as described in
Section 3.8.3, Adding DOCUMENTER Information . As
in offline operation, however, the Documenter report can still be viewed with the Print Preview toolbar but-
ton.)
4.4.5 Changing Function Block Connections Online
Configurable function block connections have a small button on the left side of the function block. Use
these input buttons to view all possible sources for the input and to change the connection.
As in the offline example, assume PV requires a +25 engineering unit offset. We’ll use the FNC function
block to add 25 to AI1.
✎ NOTES Because this dialog has a Cancel/Close button, each parameter
value change immediately takes affect in the controller.
Clicking on the Cancel button in online operation causes that dialog
to end before the changes can be entered.
Pressing the ESC key is the same as clicking on Cancel.
