data table.
2. Outline of procedures for table output function
* It is possible to write the data table directly in FX3U-4DA using a program (TO instruction, etc.).
The data table is transferred from the PLC main
unit to the relevant buffer memory of FX
3U
-4DA.
Transfer of data table*
Refer to Section 6.3
Execution of output table
Refer to Section 6.4
Preparation of data table*
Refer to Section 6.2
Setting and execution
•
Output patterns (BFM #81 to #84) of each
channel
•
The numbers of table output execution cycle
number (BFM #85 to #88) of each channel
•
Start/stop of table output function for each
channel command (BFM #80)
Data table is prepared in the data registers
