Appendix 9 Processing Time

A
SFC program switching
This section describes the processing time required to switch the SFC program from the standby status to the scan execution
type.
• Switching time [
s] = (Number of blocks created
Km) + (Number of steps created
Kn) + (SFC program capacity
Kp) +
Kq
*1 For the programmable controller CPU with firmware version "30" or earlier and for the Process CPU with firmware version "12" or earlier,
the values are as follows.
R04CPU, R04ENCPU, R08CPU, R08ENCPU, R08PCPU, R16CPU, R16ENCPU, R16PCPU, R32CPU, R32ENCPU, R32PCPU:Km =
3.97, Kn = 0.41, Kp = 0.39
R120CPU, R120ENCPU, R120PCPU:Km = 3.97, Kn = 0.41, Kp = 0.32
When the SFC program capacity is the following models or conditions, the processing time required to switch the SFC
program from the standby status to the scan execution type will be fixed.
When the SFC information device is set, the processing time required to switch the SFC program from the standby status to
the scan execution type will become longer.
