3. Details of data table
(1) Number of patterns (number of data items: 1)
Store the number of patterns at the top of the data table (device specified in BFM#98).
Up to 10 patterns can be prepared. The setting range of the number of patterns is 1 to 10.
When the number of patterns is out of the setting range, table output error code K111 is stored in
BFM#90, the device number in which the number of patterns is specified is stored in BFM#91, and b8 in
error status BFM#29 is turned on.
(2) Pattern (number of data items: 5 to 299)
A pattern refers to a predetermined flow of output. The contents of a pattern are defined by a combination
of points.
Prepare pattern data following the number of patterns to form the data table.
Up to 10 patterns can be prepared.
(3) Number of points (number of data items: 1)
Store the number of points to be used in each pattern at the top of the pattern.
Up to 99 points can be provided. The setting range of number of points is 1 to 99.
When the number of points is out of the setting range, the error code is stored in the table output error
code BFM#90, the device number or the buffer memory that has developed the table output error is stored
in BFM#91, and b8 of the error status BFM#29 is turned on.
(4) Condition after output at final point in pattern (number of data items: 1)
The condition after output at the final point in a pattern can be set to continue to output the output signal at
the final point or output the offset signal.
The setting is shown in the following table.
Set value
K0
K1
Other than above values
*1. When a value out of the setting range is set, the error code is stored in the table output error code
BFM#90, the device number or the buffer memory that has developed the table output error is stored
in BFM#91, and b8 of the error status BFM#29 is turned on.
(5) Point (number of data items: 3)
Data output point. The data indicating a point consist of output data, output update time, output update
time unit and point-to-point interpolation method.
Each pattern can have up to 99 points.
(6) Output data (number of data items: 1)
Digital value corresponding to the analog signal to be output at the point
The setting range depends on the output mode and offset/gain setting.
(7) Output update time (number of data items: 1)
Output time to the next point. The output update time for the n-th point is the output time between the n-th
point and the (n+1)-th point.
When the pattern is repeated, the output update time at the final point is used as the output time between
the final point and the first point.
When the pattern is not repeated, the output update time for the final point is ignored.
The setting range is 1 to 32767. For the unit, refer to Item (8).
When a value out of the setting range is set, the error code is stored in the table output error code
BFM#90, the device number or the buffer memory that has developed the table output error is stored in
BFM#91, and b8 of the error status BFM#29 is turned on.
