Transmission Delay Time - Mitsubishi Electric CC-Link IE Basic Reference Manual

Transmission delay time

A transmission delay time includes an input transmission delay time and an output transmission delay time.
Input transmission delay time
The input transmission delay time means the following.
• Time between when a signal (RX) is input to the slave station and when a device of the master station turns on or off
• Time between data (RWr) is input to the slave station and when the data is stored in a device of the master station
■MELSEC iQ-R, MELSEC-Q/L
Input transmission delay time (maximum) = SM + Ls  2 + SS [ms]
Item Description
SM Sequence scan time [ms]
Ls Link scan time [ms]
SS Processing time required for the slave station to reflect the input [ms] ( Manual for the slave station used)
■MELSEC iQ-F
Input transmission delay time (maximum) = SM + Ls + SS [ms]
Item Description
SM Sequence scan time [ms]
Ls Link scan time [ms]
SS Processing time required for the slave station to reflect the input [ms] ( Manual for the slave station used)
Output transmission delay time
The output transmission delay time means the following.
• Time between when a device of the master station turns on or off and when the output (RY) of the slave station turns on or
off
• Time between when data is set to a device of the master station and when the data (RWw) is output to the slave station
■MELSEC iQ-R, MELSEC-Q/L
Output transmission delay time (maximum) = SM + Ls + SS [ms]
Item Description
SM Sequence scan time [ms]
Ls Link scan time [ms]
SS Processing time required for the slave station to reflect the output [ms] ( Manual for the slave station used)
■MELSEC iQ-F
Output transmission delay time (maximum) = Ls + SS [ms]
Item Description
Ls Link scan time [ms]
SS Processing time required for the slave station to reflect the output [ms] ( Manual for the slave station used)
