The Repetitive
Rate Step (see
Screen B)
The Repetitive Rate Step box (see Screen B, item 3) is where you enter a rate of
time for how often you want the I/O scanner to send a query to the device after the
rate has timed out.
The rate displayed in the Representative Rate Step box is the rate for all entries. It
is set in multiples of 5 ms (the minimum) through 200 ms (the maximum) and
appears in the Repetitive Rate (ms) column (see Screen B, item 7).
Note: The Repetitive Rate Step box has been added to the I/O Scanner Dialog for
I/O scanner improvement.
Note: An entry in the Repetitive Rate column will be rounded up to the next multiple
that was entered in the Repetitive Rate Step box if the entry is not a multiple of the
Repetitive Rate Step. For instance:
If the entry in the Representative Rate Step box is 5 and you enter a 7 in the
Representative Rate column, the 7 in the Representative Rate column will be
rounded up to 10; if you change the Representative Rate Step to 6 and enter a 7
in the Representative Rate column, the entry in the Representative Rate column
will be rounded up to 12.
Note: The representative rate of the I/O scanner is a multiple of the rate displayed
in the Representative Rate Step box. The real representative rate being executed
by the I/O scanner service is shown in the Representative Rate column.
