Interlink Transmission Time - Mitsubishi Electric MELSEC iQ-R Series User Manual

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.
Interlink transmission time to completely transmit all set points

RX: Total number of source "RX/RY" or "RX/LB" points set in "Interlink Transmission Settings" of "Application Settings".
RY: Total number of source "LB/RY" or "LB/LB" points set in "Interlink Transmission Settings" of "Application Settings".
RWr: Total number of source "RWr/RWw" or "RWr/LW" points set in "Interlink Transmission Settings" of "Application Settings".
RWw: Total number of source "LW/RWw" or "LW/LW" points set in "Interlink Transmission Settings" of "Application Settings".

Precautions
The interlink transmission time may become longer due to the following causes.
• Communication with the engineering tool (such as CC-Link IE TSN/CC-Link IE Field diagnostics, module diagnostics)
• Execution of a link dedicated instruction
• Link refresh
• Interlink transmission between other modules
