■Link refresh processing time for the CC-Link IE Field Network module
The link refresh processing time between the CC-Link IE Field Network module and the modules mounted on the main base
unit and on the extension base unit can be calculated by the following formula.
T, R [ms] = KM1 + KM2  ((RX + RY + SB)  16 + RW
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 (RW
• RWr: Total number of points of remote register (RW
• 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". Note that the number of points that has been assigned in the reserved station is excluded.
*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.
