Step 2 - Use the Programming Software to Enter or Edit the Data
You Want to Force in the Extended Force Configuration Table
The extended force configuration table lets you specify as many as four groups
of block-transfer data words to force. Each group can contain as many as 256
words of block-transfer data. When you plan your forcing, you can group
together multiple block-transfer instructions until you reach the 256-word
maximum for each group. Keep in mind that the data in each group should be
all read data or all write data.
Specify each group by entering the address of the first block-transfer
instruction in that group in the extended force configuration table. Use the
programming software‘s edit function on the extended force configuration
table to clear entries, modify entries, or change block-transfer instructions.
Use your programming software to edit the extended force configuration
table:
1. Choose the software option that lets you modify entries in the extended
force configuration table.
2. Enter the file number and starting element.
3. Enter the file size (1-256 words).
4. Enter the direction of the instruction (R=read; W=write).
Forced data table files must be of type B, A, N, or D or this error appears:
FORCES MUST BE OF TYPE B, A, N, OR D
Data files are automatically created and their size automatically increased if
necessary. To delete or reduce the size of a data file, you must use the memory
map function of the programming software. If you configure a file using the
extended force configuration table, you must delete the file from the extended
force configuration table before you can delete it from the memory map.
