Using Link Special Relay (SB) and Link Special Register (SW)
This section explains how to use link special relay (SB) and link special register (SW).
Remark
For details about link special relay (SB) and link special register (SW), refer to the
following.
• Appendix 1 Link Special Relay (SB) List
• Appendix 2 Link Special Register (SW) List
(1) Cyclic transmission stop/restart
Cyclic transmission stop/restart is executed through the CC IE Control Network
Diagnostics, but it also can be executed with link special relay (SB) and link special
register (SW). (
Section 4.1.11 Stop/restart of cyclic transmission)
(a) Cyclic transmission stop/restart
(Cyclic transmission stop)
1) In the following link special register (SW), specify a station for stopping 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 stop (SB0003) ON.
3) When the CC-Link IE controller network module accepts a request, Cyclic
transmission stop accept status (system) (SB0052) is turned ON.
4) When the cyclic transmission stop is completed, Cyclic transmission stop
completion status (system) (SB0053) is turned ON.
5) The station No. of the station that performed the cyclic transmission stop
request is stored in Data linking stop request station (SW004A). (Saved in the
station which received the stop request.)
6) If the cyclic transmission stop is completed abnormally, an error code will be
stored in Data linking stop status (entire system) (SW0053).
7) Turn System link stop (SB0003) OFF.
