(e) When an interrupt factor occurs during link refresh
The link refresh is suspended and an interrupt program is executed.
Even if the Block data assurance per station setting is enabled in the CC-Link IE controller network
or MELSECNET/H network, this setting does not work when a device set as a refresh target is used
in the interrupt program.
In the interrupt program, do not use any refresh target device.
