A network channel includes a
source address
and a
target address
.
The source address specifies where the sender writes its data and the
target address specifies where the receiver reads the data from the
channel. Thus, when configuring, the target address should be
specified for a sender, and the source address for a receiver.
−
For a
handshake-
or
refresh channel
(one sender, one receiver),
the partner address should be specified.
Example:
BGT1 (subrack 1) and BGT2 (subrack 2) are coupled to one
another via a rack coupling. Data interface BG1___A is located on
BGT1, and data interface BG2___A on BGT2. A sender and a
receiver are to communicate via the "Channel" channel
(
handshake-
or
refresh channel
). If the sender is located at
BGT1, then the channel name should be specified at its AT input
with "[email protected]___A" and on BGT2, at the receiver,
"[email protected]___A" should be specified at its AR input.
Also refer to the figure, case 1).
The corresponding is valid for bi-directional connections (US
inputs).
−
For a
select channel
(several senders, one receiver), a source
cannot be specified, as the sender cannot be uniquely defined. The
receiver, which has the source address at its AR input cannot
specify this, as the source is not uniquely defined.
In addition to
the channel name, the receiver only specifies the characters
'@' at its AR connection
. (Refer to the Fig. case 2).
−
For a
multiple channel
(one sender, several receivers), a
destination cannot be specified, as the receiver cannot be uniquely
defined.
The sender, which specifies the target address at its
AT connection, cannot make a clear definition here, as the
target cannot be uniquely determined. In addition to the
