Chapter 2 Configuration Using Composer
Entering Flex Module Information Prior to Installation
Function blocks associated with hardware will not be available until the hardware is expected
to be present. Entering a part number for any slot (even though the module is not currently
installed) allows the programmer access to the associated function blocks. As an example, if
an FMMA-UEKA-AAAA is installed in slot one,
the function blocks that would be available are
shown in the red box. After entering a part
number such as FMLA-YEBA-AAAA in slot 2, ad-
ditional hardware dependent function blocks
will appear as shown in the blue box.
Note:
When configuring modules as described
above (not installed), all outputs will be off.
To configure the data logger to expect a mod-
ule that is not yet installed:
1. Select the desired slot and enter a valid part number in the
Expected Part Number field.
2. On the keyboard, push the
Enter key.
3. Click
Finish when complete to restart the data logger. After the restart process is com-
plete the
Function Block Diagram will appear.
Once the module is acquired, simply plug it into its assigned slot and click the
Detect Mod-
ules button. After doing so, the data logger will restart and a green flag will be displayed
for that slot number.
Configuring the Application using the Function Block Diagram
The Function Block Diagram (FBD) view is used to connect the real-world inputs and outputs
to internal data logger functions.
To enter the Function Block Diagram:
1. Click on the desired Device menu.
2. From the drop down menu click
Function Block Diagram.
