1) SFC Program Specifications
Max. 255 steps per block
Max. of 1024 steps (total
for all blocks), max. of 22
Max. of 255 sequence
One ladder block only,
max. of 255 sequence
Function exists (8 timers)
2) System processing times
1: The maximum number of sequence steps per block depends on the instruction used
for operation output or note editing setting. The number of steps (2k steps) indicated
in the table applies when "Unite (United Note)" is selected for note editing. Note that
2k sequence steps per block may not be secured when "Peripheral (Peripheral Note)"
is selected.
If note editing is not set, 2k sequence steps or more per block may be secured
depending on the instruction used.
