
This configuration provides two logical networks and three physical networks.
3) Create a bound variable and select SNCP_1 for the binding.

A bound variable configured to use SNCP_1 is sent over both physical
networks and the loss of one network will not affect the consumer receiving
bound variable over this network.
4) Create a bound variable and select both networks for the variable.

A bound variable configured for both logical networks will be sent over all
three physical networks and the loss of two logical or two physical networks
can be tolerated and the consumer will still receive the variable.
SNCP KVB Driver Timeout Values
The SNCP KVB driver has a number of timeout values which are configured via the
Resource Properties dialog box. The key settings are the MaxAge and
BindRespTimeout. These settings determine the number of binding requests a
consumer will send without getting a response before considering the bindings link as
failed and disconnecting.
ConnectTimeOut
This timeout serves two purposes:
 It is the time the resource waits to connect to a producer when a consumer
resource starts up.
 It is used to timeout a producer's response once a consumer has sent a "connect"
request to a producer. If the producer does not respond within the timeout, the
consumer sends another "connect" request. The consumer continues to send
"connect" request at intervals given by this timeout until a connection is
established.
