Bit Status Field
When creating this field a mask value and data value for a drive parameter are specified. Two character strings are
also typed in, one for the true state of the bits and one for the false state of the bit. One of the two character strings
will then be displayed depending on the status of the specified data value versus the mask value. If enabled this field
will also function as a bit modify. Moving the focus, via the
Select
key, to the field and pressing the
Enter
key will
cause the bits to be complimented by the 2800.
How the Bit Status determines which string to display:
Example 1:
Drive Value
0000 0000 0000 0001
AND with Mask Value
0000 0000 0000 0001
Results
0000 0000 0000 0001
The result is equal to the Data Value, therefore, the True Text
[STOP]
would be displayed on the 2800.
Example 2:
:
Drive Value
0000 0000 0000 0000
AND with Mask Value
0000 0000 0000 0001
Results
0000 0000 0000 0000
The result and Data Value are not equal, therefore, the False Text
[START]
would be displayed on the 2800.
