Appendix 7 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 processing time [s] = (Number of blocks created Km) + (Number of steps created Kn) + (SFC program
capacity Kp) + Kq
*1 For the firmware version "12" or earlier, the values are as follows.
R08PCPU, R16PCPU, R32PCPU: Km = 3.97, Kn = 0.41, Kp = 0.39
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.
