Appendix 2.2 Network status at board reset

The network status when the board reset from the utility or board reset from MELSEC data
link library (mdBdRst function, mdBdModSet function) is executed during data linking is
shown below.
No.
1 Before board reset
2 During board reset
3 After board reset

Time frame
*1: The status can be checked on the <<Monitor detail>> tab on the "Logging" screen of the CC IE
Control utility, on the Network diagnostics of GX Developer connected to other station's
programmable controller or at special registers.
*2: The status can be checked on the board list (Start-up) screen of the CC IE Control utility, on the
Network diagnostics of GX Developer connected to other station's programmable controller or at
special registers "Baton pass status of each station (SW00A0 to SW00A7)".
*3: The status can be checked at the "Select station network device status display" on the "CC-Link IE
Controller Network diagnostics result" of the CC IE Control utility, on the Network diagnostics of
GX Developer connected to other station's programmable controller or at special registers "Cyclic
transmission status of each station (SW00B0 to SW00B7)".
*4: When a CC-Link IE Controller Network board is reconnected/disconnected to the CC-Link IE
Controller Network, the all station error may occur for the circuit control period
50ms, Worst value: 100ms). If the all station error occurs, an error is detected in the
communication status (baton pass status) and the data link status (cyclic transmission status) of all
station.
*5: Since the board is reset during the driver operation, a brief loopback occur. An error is also
detected in the communication status (baton pass status) and the data link status (cyclic
transmission status).
*6: The circuit control period is a period to reconstruct the data link when the CC-Link IE Controller
Network board is reconnected/disconnected (such as when the cable is disconnected or the power
is turned from OFF to ON).
