Changing program capacity (FX5U/FX5UC CPU module only)
When the program capacity setting parameter is changed to 128000 steps from 64000 steps, the operation changes as
follows.
• Signal flow area for FB is expanded from 16K bytes to 32K bytes.
• Temporary area capacity is expanded form 700 words to 32767 words.
• Execution time for each instruction is prolonged.
Do not write a program with more than 64000 steps to the CPU module firmware version earlier than 1.100. The program
does not operate normally.
For the program capacity setting, refer to the following.
