Appendix 5.1
The following are formulas to calculate the link refresh time.

(1) Calculation formula

,
T
R
T:
Sending-side link refresh time
R:
Receiving-side link refresh time
RX:
Total number of RX points that are actually being link-refreshed
RY:
Total number of RY points that are actually being link-refreshed
RWr:
Total number of RWr points that are actually being link-refreshed
RWw:
Total number of RWw points that are actually being link-refreshed
SB:
Number of SB points
SW:
Number of SW points
E:
Memory card file register (R, ZR), extended data register (D), and extended link register (W) transfer time
L:
Interlink transmission time (
KM1, KM2, KM3: Constant
*1
Total number of link device points for the range set by the refresh parameters and set in the network configuration
settings. Note that the points assigned to reserved stations are excluded.
Remark
• Add E only when refreshing the data to the memory card file register. Addition is not required when refreshing
the data to the standard RAM and extended SRAM cassette file registers.
• Add L only when using the interlink transmission.
