240 Parameters
Pointer Value pointer setting (see Terms and abbreviations on page
102).
-
57.08 Follower cw src Selects the source of the D2D control word sent to the
followers. The parameter is effective on the master drive, as
well as submasters in a multicast message chain (see
parameter 57.11 Ref1 msg type)..
Pointer Value pointer setting (see Terms and abbreviations on page
102).
-
57.11 Ref1 msg type By default, in drive-to-drive communication, the master
broadcasts the drive-to-drive control word and references 1
and 2 to all followers. This parameter enables multicasting,
i.e. sending the drive-to-drive control word and reference 1 to
a certain drive or group of drives. The message can then be
further relayed to another group of drives to form a multicast
chain.
In the master, as well as any submaster (i.e. follower relaying
the message to other followers), the sources for the control
word and reference 1 are selected by parameters 57.08
Follower cw src and 57.06 Ref 1 src respectively.
Note: Reference 2 is broadcast by the master to all followers.
Broadcast The control word and reference 1 are sent by the master to all
followers. If the master has this setting, the parameter has no
effect in the followers.
0
Ref1 MC Grps The drive-to-drive control word and reference 1 are only sent
to the drives in the multicast group specified by parameter
57.13 Next ref1 mc grp. This setting can also used in
submasters (followers in which parameters 57.03 Node
address and 57.12 Ref1 mc group are set to the same value)
to form a multicast chain.
1
57.12 Ref1 mc group Selects the multicast group the drive belongs to. See
parameter 57.11 Ref1 msg type.
0…62 Multicast group. 1 = 1
57.13 Next ref1 mc grp Specifies the next multicast group of drives the multicast
message is relayed to. See parameter 57.11 Ref1 msg type.
This parameter is effective only in the master or submasters
(followers in which parameters 57.03 Node address and
57.12 Ref1 mc group are set to the same value).
0 No group selected. 0
1…62 Next multicast group in the chain. 1 = 1
57.14 Nr ref1 mc grps Sets the number of drives sending messages in the message
chain. The value is typically equal to the number of multicast
groups in the chain assuming that the last drive is NOT
sending an acknowledgement to the master. See parameter
57.11 Ref1 msg type.
Note: This parameter is only effective in the master.
1…62 Number of links in the multicast chain. 1 = 1
57.15 D2D com port Defines the hardware to which the drive-to-drive link is
connected. In special cases (such as harsh operating
conditions), the FMBA module may make for more robust
communication than the standard drive-to-drive connection.
