The number of steps of the FB embedded in a program depends on the CPU module used, the input/output definitions,
and the options setting of GX Works3. For the options setting of GX Works3, refer to the following.
 GX Works3 Operating Manual
• Label: 5268 points (word)
• Latch label: 0 points (word)
The usage of labels embedded in a program depends on the CPU module used, the devices specified as an argument,
and the options setting of GX Works3. For the options setting of GX Works3, refer to the following.
 GX Works3 Operating Manual
• Index register: 0 points
• Long index register: 1 point (device number used: LZ0)
When using interrupt programs, do not use the corresponding index register in the interrupt programs.
Logging data must be stored in the file register. Refer to the following calculation formula and set the file register capacity.
File register (ZR) capacity = i_udDataAddr (start address of the storage location of logging data) + (i_uCHNum (number of
channels)  i_udSavePoints (number of save points))
For the setting method, refer to the following.
