How to Configure the Island
EIO0000000051 6/2010 61
NOTE: You must put the island configuration in edit mode before you edit the
reserved size of the HMI/PLC tables. The island configuration is in edit mode when
it is unlocked. To unlock a locked island, place the Island → Lock menu command
in the unlocked (up) position.
Data Transfer: To transfer data to the PLC from a Modbus HMI panel attached to
the CFG port, you must reserve space for that data:
Restoring Default Values
After the Reserved Size (Words) of HMI to PLC Table or the
Reserved Size (Words) of PLC to HMI Table value has been edited, you can
restore the default values for both parameters by clicking the
Restore Default Values button.
Selecting the Display Format
By default, the values for the configurable NIM parameters use decimal notation.
You can change the display format to hexadecimal notation, and vice-versa:
Step Action
1 Double-click the NIM in the island editor. The module editor opens.
2 In the module editor, select the Parameters tab.
3 In the Data Item Name column, expand the NIM Parameters List by clicking on the
plus (+) sign. (The configurable data transfer parameters are displayed.)

HMI to PLC table. The value is highlighted.
5 Type a value for the data size to be reserved for data sent from the HMI panel to the
PLC.
NOTE: The value plus the data size of your island cannot exceed the maximum value.
If you accept the default value (0), no space is reserved in the HMI table in the process
image.
