This is performed by connecting a physical push-button to the digital input. The
system waits for 30 minutes for the acknowledgement, if acknowledgement is not
received the inserted SM811 will shut down. To recover, a new hot insert needs to be
initiated i.e. the SM811 has to be removed and inserted again.
Synchronization of the SM811 includes:
1. Make sure that the synchronization link between the SM811s is in place, that
is, the enclosed TK852V010 cable is properly connected into both SM Link
connectors respectively.
2. Insert the SM811 in its position.
3. When the SM811 starts the synchronization LED flashes, and later it continues
to blink with 3 blinks and a pause in a sequence.
4. Push the button (create an edge on digital input 3 on the already running Safety
Module), once it starts blinking repeatedly with 3 blinks and a pause sequence.
5. The Sync LED flashes faster until the synchronization is complete.
6. The Sync LED turns yellow when the module is synchronized.
Make sure that SM Link Cable TK852V010 is connected before hot-insert and
OLU. The SM Link Cable TK852V010 can be replaced if needed, except during
hot-insert and OLU. Removing the cable results in a diagnostic error and the
cable must be repaired or replaced.
Non-SIL and SIL1-2 applications are not affected by synchronization of SM811.
They continue to execute as normal throughout the entire synchronization
without being interrupted.
A Hot Swap of SM811 requires the two safety modules to be connected with a
synchronization link, used to transfer the application state.
During a hot swap it is not possible to download a new configuration from
Control Builder, the controller is reserved. The Control Builder user is notified
with an information dialog. The reservation is released when the hot insert is
concluded or aborted. If a configuration download is ongoing, then the hot insert
starts after the download is completed.
