8.3 Using Link Special Relay (SB) and Link Special Register (SW)
(b) Cyclic transmission restart of another station
1. In the following link special register (SW), specify a station for restarting cyclic transmission.
• Specification of target station
Link stop/startup direction (SW0000)
• Specification of station No.
Link stop/startup direction (SW0001 to SW0008)
• Specification of group
Group specification for link stop/startup (SW0012 to SW0013)
2. Turn System link startup (SB0002) ON.
3. When the CC-Link IE Controller Network module accepts a request, Cyclic transmission start
accept status (SB0050) is turned ON.
4. When the cyclic transmission restart is completed, Cyclic transmission start
completion status (SB0051) is turned ON.
5. If the cyclic transmission restart is completed abnormally, an error code will be stored in Data
linking start status (entire system) (SW0051).
6. Turn System link startup (SB0002) OFF.
(c) Cyclic transmission stop of own station
1. Turn Link stop (own station) (SB0001) ON.
2. When the CC-Link IE Controller Network module accepts a request, Cyclic transmission stop
accept status (own station) (SB004E) is turned ON.
3. When the cyclic transmission stop is completed, Cyclic transmission stop completion status (own
station) (SB004F) is turned ON.
4. If the cyclic transmission stop is completed abnormally, an error code will be stored in Data
linking stop status (own station) (SW004F).
5. Turn Link stop (own station) (SB0001) OFF.
