Ctrl Command master_slave_config
Function Sets settings for the master-slave interface of an RTC6 board.
Call master_slave_config( Config )
Parameters Config As an unsigned 32-bit value.
Bit #0 Suppression of /Slave-START signals and /Slave-STOP signals.
= 0: /Slave-START and /Slave-STOP signals via the master-slave
interface are received and processed.
= 1: /Slave-START and /Slave-STOP signals received by this board
via the master-slave interface are ignored on this board, but
are forwarded to other boards of the master-slave interface.
Bit #1 /STOP in case of master-slave faults.
= 0: The board does not react explicitly to a fault in the
master-slave connection. Any effects are undefined.
= 1: Triggers a /STOP, if the connection to the master card is
interrupted. This occurs, for example, if load_program_file is
executed on a card of the already synchronized master-slave
chain, the master-slave cable is removed or the signal of the
master-slave interface is electromagnetically disturbed.
Bit #2 Forwarding /STOP in case of master-slave faults.
= 0: A /STOP is not forwarded to other boards.
= 1: If an error of the master-slave connection is detected and a
/STOP is triggered (see Bit #1), this /STOP is forwarded to all
still connected cards of the master-slave chain (also upwards
to a master card).
Comments • For usage of master_slave_config, see Chapter 6.6.3 ”Master/Slave Operation”,
page 124.
• The master-slave interface of a board should normally only be configured after
successful synchronization.
• If Bit #0 is already set before sync_slaves, this board cannot be synchronized to a
master board with sync_slaves.
• In certain other malfunction scenarios, fault-free operation may no longer be possible.
In this case, a /STOP is always performed on the affected board, even if Bit #1 = 0.
• If the connection to a master-slave synchronized board is disturbed, this can also result
in further boards in the chain being disturbed, and thus execute a /STOP, even if Bit #2
is not set.
