You can use the sYnch  window, then the synchronization is done by software with about a millisecond delay.

Otherwise, you can get a hardware-based synchronization if the chip supports BDGREQ and DBGACK signals. In this case, you can connect both debug modules over PODBUS and use the commands TrBus.Out Break ON and TrBus.Set Break ON for each PowerView instance. This type of synchronization is however not supported for synchronous start (Go).

Refer for more information to the documentation of these commands in General Commands Reference Guide T.
