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 clear, the view remains blank (default). If the checkbox is
selected, then the mapping tree appears which allows the user to configure the Control Word(s) as desired. This checkbox
enables both Control Words and Status Words, and the two cannot be enabled/disabled independently.
Number of Control Words
The user can specify the number of desired 16-bit Control Words for the application. This parameter is adjustable from 1 to 4
words (1 default) using the arrows next to the box. The Number of Control Words cannot be adjusted while online with the
device. If online, the user must disconnect communications and then adjust the number of control words.
