■If an interrupt factor occurs during link refresh
The link refresh is suspended and the fixed scan execution type program is executed. Even while the station-based block data
assurance is enabled for cyclic data during refresh of such links as CC-Link IE Field Network, if the fixed scan execution type
program uses a device specified as the refresh target, the station-based block data assurance for cyclic data is not available.

■If another interrupt occurs while the fixed scan execution type program is being executed
If an interrupt program (including an interrupt which triggers the event execution type program) is triggered while the fixed
scan execution type program is being executed, the program operates in accordance with the interrupt priority. ( Page
129 Multiple interrupt function)
Processing when the fixed scan execution type program starts
The same processing as when the interrupt program starts. ( Page 126 Processing at interrupt program startup)
