Test Before CC-Link IE Controller Network Operation

This section describes the test performed before operation of the CC-Link IE Controller Network.
The test checks, before system operation, whether transient transmission can be correctly routed in the network or not.
5.7.1

Communication test

Communication test checks if transient transmission data can be properly routed from the own station to the
communication target.
Note that this test is not available in circuit test mode.
(1) System configuration
Connect the programming tool to the CPU module of the own station.
For an example, assume the following multi-network system.
1M
1N
(2) Setting routing parameters in the programming tool
Set routing parameters in the programming tool for each station on the network, and write them to the
programmable controller. (
(a) Routing parameters for stations of the network No.1
(b) Routing parameters for stations of the network No.2
(c) Routing parameters for stations of the network No.3

No setting is required for the relay station 1 (1N
because data are transmitted via the own station.
