(Cyclic transmission restart)
8) 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)
9) Turn System link startup (SB0002) ON.
10)When the CC-Link IE controller network module accepts a request, Cyclic
transmission start accept status (SB0050) is turned ON.
11)When the cyclic transmission restart is completed, Cyclic transmission start
completion status (SB0051) is turned ON.
12)If the cyclic transmission restart is completed abnormally, an error code will be
stored in Data linking start status (entire system) (SW0051).
13)Turn System link startup (SB0002) OFF.
