CHAPTER 7 PARAMETER SETTING

7.7 Routing Parameters
*1 Routing parameters need not to be set for stations for which routing parameters are not available (e.g. station including
a head module). The station communicates with other networks according to routing parameters set to the master
station.
● Transient transmission range
Communications can be made with stations up to eight networks apart (number of relay stations: 7).
● Setting for stations that do not perform transient transmission to other networks
Routing parameters are not required for stations that do not perform transient transmission to other networks; however,
setting the same routing parameters to all stations is recommended.
Note that routing parameters need not to be set for stations for which routing parameters are not available (e.g. station
including a head module). The station communicates with other networks according to routing parameters set to the
master station.
(2) Checking method
To check whether routing parameters have been correctly set and transient transmission can be performed,
perform a communication test from CC-Link IE Field Network diagnostics. ( Page 75, Section 6.4.3)
(3) Precautions
(a) Different control CPUs are set to the network modules on a relay station in a
multiple CPU system
Set the same routing parameters to all the control CPUs.

Network No.
Station which does not perform
transient transmission
It is recommended to set the same routing parameters as for .
and can communicate by the same routing parameters,
since they pass through the same relay station.
