1 GENERAL DESCRIPTION
(3) Ease of division editing of blocks and steps according to control object
• A total of 320 blocks
1 can be created in a whole SFC program.
• Up to 512 steps
2 can be created in a single block.
• Up to 2k sequence steps of operation outputs/transition conditions can be created in all
blocks. By dividing blocks and steps as shown below, tact time can be shortened and
debugging/test operation can be performed easily.
• Blocks are divided properly according to the operation units of machines.
• Steps in each block are divided properly.
