4. Cautions regarding table output
• When BFM #99 (data table transfer command) is not H0000, the table output function cannot be started.
• When an error occurs during transfer of data table, start the table output after setting the correct data table.
• While the table output completion flag BFM #89 is ON, output of a new table cannot be started.
• The table output function is valid only while the PLC is in RUN mode.
• While even a single channel is outputting data table (BFM #80 is not H0000), it is prohibited to change
BFM #0, #5, #9 to #17, #19, #20, #32 to #35, #38, #41 to 48, #50 to #54 and #60 to #63.
• The pattern can be changed during output as shown below. (The change is invalid while the table output
completion flag BFM #89 is ON.)
5. Check the table output completion flag. (BFM #89, initial value: H0000)
The value in BFM #89 indicates whether the table output from each channel has been completed.
After data is output at the final point in the last cycle of a pattern, the table output completion flag is turned on.
When the table output (BFM#80) is set to be stopped, the table output completion flag is turned off.
