Procedures for executing table output function
After setting the output patterns for the channels (BFM #81 to #84) and the number outputs for the
channels (BFM #85 to #88), turn on the table output function start/stop command (BFM #80) to
execute the table output function.
1. Set the output patterns for the channels. (BFM #81 to #84, initial value: K1)
Set the output patterns for the channels in BFM #81 to #84.
The output pattern can be changed in the middle of outputting the table.
Setting range for BFM #81 to #84: 1 to 10
When a value out of the setting range is set, the error code K31 is stored in the table output error code BFM
#90, the number of the buffer memory (K81 to K84) that has developed the table output error is stored in BFM
#91, and b8 of the error status BFM #29 is turned on.
2. Set the number of table outputs for the channels. (BFM #85 to #88, initial value: K0)
Set the number of table outputs for the channels in BFM #85 to #88.
The number of outputs can be changed even during outputting the table.
Setting range for BFM #85 to #88: 0 to 32767
When 0 is set, output of the table will be repeated until the table output is stopped by BFM #80.
When a value out of the setting range is set, the error code K32 is stored in the table output error code BFM
#90, the number of the buffer memory (K85 to K88) that has developed the table output error is stored in BFM
#91, and b8 of the error status BFM #29 is turned on.
3. Table output start/stop (BFM #80, initial value: H0000)
Table output is started and stopped by setting BFM #80 as shown below.

Set value
Description
0
The table output function of each channel is stopped.
1
The table output function of each channel is started.
After output at the final point in the last cycle, 0 will be
automatically written.
Other than above
values
Invalid*
* When a value out of the setting range is set, the error code K33 is stored in the table output error code BFM
#90, the number of the buffer memory (K80) that has developed the table output error is stored in BFM #91,
and b8 of the error status BFM #29 is turned on.
