(2) How to calculate the transmission delay time
(a) Delay time in cyclic transmission
Calculation formulas for cyclic transmission delay time (time required for data to
be delivered) are shown below.
1) For a single network system
* 1 When a C Controller module (another CPU) receives data
* 2 When a programmable controller CPU receives data
L
T
: Link device refresh cycle of C Controller module (sending side)
L
R
: Link device refresh cycle of C Controller module (receiving side)
T
: Total link device refresh time of C Controller module (sending side)
*3
( (1) (b) in this section)
R
: Total link device refresh time of C Controller module (receiving side)
*3
( (1) (b) in this section)
S
R
: Scan time (excluding the link refresh time) of the programmable
controller CPU (receiving side)
*4
R
: Link refresh time of the programmable controller CPU (receiving side)
*3,
*4
LS: Link scan time
*4
* 3 Total time for the number of mounted CC-Link IE controller network modules.
* 4 For details, refer to the MELSEC-Q CC-Link IE Controller Network Reference Manual.
2) For a multi-network system
Transferring link device data to another network using the interlink transfer
function will affect the transfer processing time of CPU modules on relay
stations.
For details, refer to the MELSEC-Q CC-Link IE Controller Network Reference
Manual.
