■Link refresh processing time for the CC-Link IE Field Network module
The link refresh processing time between the CPU module and the CC-Link IE Field Network module on the main base unit or
the extension base unit is calculated by the following formulas.
T, R [ms] = KM1 + KM2  ((RX + RY + SB)  16 + RWr + RWw + SW) + U
U [ms] = KM3  (SBU  16 + SWU)
• T: Link refresh time (sending side)
• R: Link refresh time (receiving side)
• U: Unit label (SB/SW) refresh time
• RX: Total number of points of remote input (RX) refreshed by the master station/local station
• RY: Total number of points of remote output (RY) refreshed by the master station/local station
• RWw: Total number of points of remote register (RWw) refreshed by the master station/local station
• RWr: Total number of points of remote register (RWr) refreshed by the master station/local station
• SB: Number of points of link special relay (SB)
• SW: Number of points of link special register (SW)
• SBU: Number of points of link special relay (SB)
• SWU: Number of points of link special register (SW)

*1 Total number of points here indicates the one of link devices that have been set in "Refresh Setting" and "Network Configuration
Settings".
*2 Number of points here indicates the one of when module label is not used. Calculation is executed while it is regarded as "0" when
module label is used.
*3 Number of points here indicates the one of when module label is used. Calculation is executed while it is regarded as "0" when module
label is not used.
*4 The base units here indicates the type of base unit where the network module targeted for refresh is mounted.
