on the Ember+ Consumer
Ember+ SrcRepl
Reference name for the element.
SrcRepl Element Nr
Enter a Source Replication element number (e.g. 1).
This will be used to identify each source you wish to replicate (described below). The same
number can be used to replicate several sources.
Local Consumer Nr
Enter the Local consumer
, as defined in the "System -> Definition -> Parameter =
Local Consumers" branch of the 'Tree Definition'.
Enable Replication
Enter a control signal to enable the replication.
Replication Consumer ->
Provider
Replication Provider ->
Consumer
Use these options to determine whether the replication is one-way or bi-directional. Tick both
checkboxes for bi-directional replication.
Initial Replication
Direction
This option determines the initial replication direction. It affects what happens after a system
restart or interruption to the Ember+ connection. There are three possibilities:
Provider ->
Consumer
,
Consumer -> Provider
and
By Negotiation
.
If
By Negotiation
is selected, then the provider and consumer negotiate over who has the
most current data. This information is then used to determine the initial replication direction.
The negotiation compares whether the provider or consumer have already been replicated
during runtime as follows.
·
If no communication has occurred, then the system which started first replicates its
parameters to the other system.
·
If communication has occurred and only one of the systems has exchanged parameters,
then this system replicates its parameters to the other system.
·
If communication has occurred and both systems have exchanged parameters, then the
time stamp of the last exchange decides the replication direction.
Fader Included, etc.
Use these options to determine which parameters are replicated.
