Enable Packed Bits Control and Status Words
In order to use the Pack Bits Control Word and Status Word mapping, the function must be enabled by activating the Enable Packed Bits
Control and Status Words checkbox. If the checkbox is unchecked, the view remains blank (default). If the checkbox is checked, then the
mapping tree appears which allows the user to configure the Status Word(s) as desired. This checkbox enables both Control Words AND
Status Words, and the two cannot be enabled/disabled independently.
Number of Status Words
The user can specify the number of desired 16-bit Status Words for the application. This parameter is adjustable using the spinner control from
1 to 4 words (1 default). The Number of Status Words cannot be adjusted while online with the device. If online, the user must disconnect
communications and then adjust the number of status words.
Status Word Setup Tab
The Status Word Setup Tab is used to map the desired bit-level parameters onto the existing status word(s). The method for mapping
parameters to the Status Word(s) is the same as for the Control Words. See the Drag and Drop and Add Button methods described in the
Control Words section above.
To delete parameters from the Status Word, simply drag and drop the parameter off the status word (see explanation above), or highlight the
desired parameter to delete, and click the Delete button on the right side of the view.
NOTE
Parameters can be mapped while online, but cannot be sent to the drive using the Update to RAM function. Therefore, any changes to Status
Word mapping requires a full download.
Online Status Tab (Available Online Only)
While online with the device, the user can monitor the Status Word value (see Figure 91). The data is displayed in binary form for each
individual bit of the Status Word(s), as well as hexidecimal and decimal format for each Status Word.

Using Pack Bits Status Words
Once the Status Word(s) have been configured by the user, they can be utilized by fieldbus communications (i.e. Modbus, EtherNet I/P,
Profibus, DeviceNet, etc.) or within a user program. Figure 92 below shows an example in which the user will read Status Word 0 from the
drive via Ethernet I/P.
