Network Topology
Select the network topology type according to the actual network configuration.
Setting is not required and can be left as "Line/Star" (default).
Communication Period Setting
Perform basic cycle setting and multiple cycle setting.
• Basic cycle setting requires calculation of the communication cycle interval and cyclic transmission time. ( Page 286
Communication cycle intervals)
• Multiple cycle setting is used when communication cycles coexist. ( Page 39 Communication cycle coexistence)
• When the industrial switch (for CC-Link IE TSN Class B) is used, set the timeslot information from the
setting values in "Basic Period Setting". The timeslot information can be checked with the buffer memory.
( Page 257 Timeslot information)
• Set "Communication Period Setting" according to the communication cycle supported by the device
stations.
