Processing Time

This section shows the processing time of the cyclic transmission related to network module access.
For the processing time of the transient transmission, refer to the processing time of each function.

Link refresh time

The following shows the processing time of link refresh.
CC-Link IE Controller Network
The processing time when using CC-Link IE Controller Network is as follows:
• 
: Total link refresh time (sending side)
T
• 
: Total link refresh time (receiving side)
R
• KM1, KM2: Constant
Network module mounting position
Main base unit
Extension base unit
• LB: Total number of points of link relays to be refreshed
• LX: Total number of points of link inputs to be refreshed
• LY: Total number of points of link outputs to be refreshed
• LW: Total number of points of link registers to be refreshed
*1 The total number of points of link devices set for the setting range of "Refresh Setting" and "Network Range Assignment" ("Network
Configuration Settings"). The number of points assigned to a reserved station is not included.
Link refresh time can be calculated by the following formula with the number of assigned points of link devices.

CC-Link IE TSN
The processing time when using CC-Link IE TSN is as follows:
• 
: Total link refresh time (sending side)
T
• 
: Total link refresh time (receiving side)
R
• KM1, KM2: Constant
Network module mounting position
