Appendix 3 Buffer Memory
Communication cycle setting value ( CC-Link IE TSN Protocol version 2.0)
Communication cycle interval (calculation value) (Un\G44596)
The communication cycle interval calculated by the number of device stations and the number of points that are set in
"Network Configuration Settings" under "Basic Settings" are stored. (Unit: s)
The communication cycle interval (CC-Link IE TSN Protocol version 2.0) are stored regardless of the setting value of 'Protocol
setting' (Un\G44322). If the device that supports CC-Link IE TSN Protocol version 2.0 and a device that supports the CC-Link
IE TSN Protocol version 1.0 coexist, and if 'Protocol setting' (Un\G44322) is set to "1": CC-Link IE TSN Protocol version 1.0
fixed, refer to the value of this buffer memory and set the value to "Communication Period Interval Setting" in "Communication
Period Setting" under "Basic Settings".
Cyclic transmission time (calculation value) (Un\G44597)
The cyclic transmission time calculated by the number of device stations and the number of points that are set in "Network
Configuration Settings" under "Basic Settings" is stored. (Unit: s)
The cyclic transmission time (CC-Link IE TSN Protocol version 2.0) is stored regardless of the setting value of 'Protocol
setting' (Un\G44322). If the device that supports CC-Link IE TSN Protocol version 2.0 and a device that supports the CC-Link
IE TSN Protocol version 1.0 are coexistence, and if 'Protocol setting' (Un\G44322) is set to "1": CC-Link IE TSN Protocol
version 1.0 fixed, refer to the value of this buffer memory and the value is set to "Cyclic Transmission Time" in
"Communication Period Setting" under "Basic Settings".
Transient transmission time (Calculation value) (Un\G44598)
The transient transmission time calculated by the number of device stations and the number of points that are set in "Network
Configuration Settings" under "Basic Settings" is stored. (Unit: s)
The transient transmission time (CC-Link IE TSN Protocol version 2.0) are stored regardless of the setting value of 'Protocol
setting' (Un\G44322). If the device that supports CC-Link IE TSN Protocol version 2.0 and a device that supports the CC-Link
IE TSN Protocol version 1.0 are coexistence, and if 'Protocol setting' (Un\G44322) is set to "1": CC-Link IE TSN Protocol
version 1.0 fixed, refer to the value of this buffer memory and the value is set to "Transient Transmission Time" in
"Communication Period Setting" under "Basic Settings".
Information for device station cyclic transmission
Multiplier for transmission delay information of CC-Link IE TSN Class A (low-speed)
(Un\G44608)
The multiplier n is stored for calculating the transmission delay time for device stations for which "CC-Link IE TSN Class A" is
set and "Communication Period Setting" is set to "Low-Speed".
• 0: There are no device stations for which "CC-Link IE TSN Class A" is set and "Communication Period Setting" is set to
"Low-Speed" in the network configuration.
• 1 or higher: Value of n
If Protocol operating status (Un\G44320) is "1" (A device is operating with the CC-Link IE TSN Protocol version 1.0), this is
fixed to 1.
