3.3.5 Fixed scan execution type program
(c) Execution during network refresh
When the execution condition for the fixed scan execution type program is
satisfied during network refresh, network refresh is suspended and the fixed scan
execution type program is executed.
Even if the cyclic data block has been assured for each station in the CC-Link IE
controller network or the MELSECNET/H network system, it is not available when
the device set as a refresh target is used in the fixed scan execution type
program.
In the fixed scan execution type program, do not use the device set as a network
refresh target.
Refer to the following manual for the block guarantee of cyclic data per station.
