■Link refresh processing time for the MELSECNET/H network module
The link refresh processing time between the CPU module and the MELSEC iQ-R series MELSECNET/H network module on
the main base unit or the extension base unit is calculated by the following formulas.
T, R [ms] = KM1 + KM2  ((LB + LX + LY + SB)  16 + LW + 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
• LB: Total number of points of link relay (LB) that is refreshed by the station
*1
• LW: Total number of points of link register (LW) that is refreshed by the station
*1
• LX: Total number of points of link input (LX) that is refreshed by the station
*1
• LY: Total number of points of link output (LY) that is refreshed by the station
*1
• SB: Number of points of link special relay (SB)
*2
• SW: Number of points of link special register (SW)
*2
• SBU: Number of points of link special relay (SB)
*3
• 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.
The link refresh processing time between the CPU module and the MELSEC-Q series MELSECNET/H network module on
the RQ extension base unit or the Q series extension base unit is calculated by the following formulas.
T, R [ms] = KM1 + KM2  ((LB + LX + LY + SB)  16 + LW + SW)
• T: Link refresh time (sending side)
• R: Link refresh time (receiving side)
• LB: Total number of points of link relay (LB) that is refreshed by the station
*5
• LW: Total number of points of link register (LW) that is refreshed by the station
*5
• LX: Total number of points of link input (LX) that is refreshed by the station
*5
• LY: Total number of points of link output (LY) that is refreshed by the station
*5
• SB: Number of points of link special relay (SB)
• SW: Number of points of link special register (SW)
*5 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.
*6 The base units here indicates the type of base unit where the network module targeted for refresh is mounted.
