Table App.16 Comparison of RAS functions
Function Compatibility Precautions for replacement
Detection of duplicated control station or station No. None
Control station switching None
Sub-control station performs data link when
control station went down.
No setting item is provided for the CC-Link IE
controller network module.
The sub-control station always continues data
link when the control station goes down in the
CC-Link IE controller network.
Control station return control
The CC-Link IE controller network module
does not have setting items.
The data link will be continued even when a
station returns as a control station in the
CC-Link IE controller network.
Automatic return None
Max. number of returned stations at one scan
The CC-Link IE controller network module
does not have setting items.
The CC-Link IE controller network does not
have restriction on the maximum number of
returned stations.
Loopback None
Detection of time of transient transmission error completion None
Transient transmission in the case of a CPU module error None
Prevention of station failure by external power supply
Operation is different when power is applied
during reset of CPU module.

Module
Hardware test
Set to the test mode at network parameters in
the CC-Link IE controller network module.
Self-loopback test
Internal self-loopback test
The hardware test includes the internal
self-loopback test in the CC-Link IE controller
network module.
At system startup
Station-to-station test
The station-to-station test is set to executing
stations only in the CC-Link IE controller
network module.
Set online mode to the target station.
Forward loop test, reverse loop
test
The circuit test includes the forward and
reverse loop tests in the CC-Link IE controller
network module.
Before system operation
Communication test None
Loop test
The circuit test includes the loop test, setup
confirmation test, and station order check test
in the CC-Link IE controller network module.
Setup confirmation test
Station order check test
