Value Description
15 (“Int Connect,set Async”) The network is internally connected and setting
Synchro-
check mode
in ASNSCSYN is "Asynchronous".
16 (“Externally connected”) The network is externally connected.
17 (“Int Async,set Sync”) The network is internally asynchronous and setting
Synchro-
check mode
in ASNSCSYN is "Synchronous".
Internally connected
A network where Bus1 is connected to Bus3, Bus2 is connected to Bus4 and CB1 is
closed is seen as an internally connected network by CB2.

Externally connected
A network where both Bus3 and Bus4 are connected to the grid across CB1 is
considered an externally connected network.

The number of sources active in the voltage and frequency matching is shared to
sources via the corresponding output signal ASC_SRC1_DAT...ASC_SRC8_DAT.
The binary input BLOCK can be used to block the function. The activation of the
BLOCK input deactivates all binary outputs and resets the internal timers.
