A
Interlink transmission time
The following is the formula to calculate the time required for interlink transmission. Interlink transmission does not affect the
sequence scan time.
Refer to the following for the case that the transfer source module is a master/local module.
MELSEC iQ-R CC-Link IE Field Network User's Manual (Application)
Interlink transmission time to completely transmit all set points
DL
= KM4 ((RX + RY) 16 + RWr + RWw) [ms]
DL
: Interlink transmission time
RX: Total number of source "RX/LB" points set in "Interlink Transmission Settings" of "Application Settings"
RY: Total number of source "LB/RY" points set in "Interlink Transmission Settings" of "Application Settings"
RWr: Total number of source "RWr/LW" points set in "Interlink Transmission Settings" of "Application Settings"
RWw: Total number of source "LW/RWw" points set in "Interlink Transmission Settings" of "Application Settings"
• Constant (KM4)
Precautions
The interlink transmission time may become longer due to the following causes.
• Communication with the engineering tool (CC-Link IE Field Network diagnostics, module diagnostics, etc.)
• Execution of a link dedicated instruction
• Link refresh
• Interlink transmission between other units
