(c) Link refresh time of CC-Link IE Field Network Basic
This is the time required for refresh of CC-Link IE Field Network Basic.
[Refresh time of CC-Link IE Field Network Basic]
T = KM1 + KM2  (((RX + RY)  16) + RWw + RWr) + E [s]
E = KM3 + KM4  (((RX + RY)  16) + RWw + RWr) [s]
• T: Link refresh time
• E: Link refresh time when the file register (R, ZR) is used
• RX: Number of points of remote input (RX) refreshed by the master station
• RY: Number of points of remote output (RY) refreshed by the master station
• RWw: Number of points of remote register (RWw) refreshed by the master station
• RWr: Number of points of remote register (RWr) refreshed by the master station
• KM1 to KM4: Constant

*1 This time is added when the file register (R, ZR) is used.
*2 This value is determined according to the number of slave stations to be connected and the number of occupied
stations.
(d) Auto refresh time via intelligent function modules
This is the time required for refreshing data between the buffer memory of an intelligent function module and
devices in the CPU module.
