Sfc Program Switching - Mitsubishi Electric MELSEC iQ-R-R00CPU User Manual

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
Constant Constant value
R00CPU, R01CPU, R02CPU
Km 7.90
Kn 1.85
Kp 0.21
Kq 2550
*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.
Model
• The R04CPU, R04ENCPU, R08CPU, R08ENCPU, R16CPU,
R16ENCPU, R32CPU, and R32ENCPU with firmware version
"30" or earlier
• R08PCPU, R16PCPU, R32PCPU
• The R120CPU and R120ENCPU with firmware version "30" or
earlier
• R120PCPU
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.
