SourceSubnetId
Summary Indicates the subnet ID of the device making a network
variable update to a host network variable.
This value is only meaningful if the network variable being
monitored is a host network variable. This property, along
with the SourceNodeId property, allows a number of devices
on the network to each have a network variable explicitly
bound to a single network variable on the host. Once the
network variable has been bound and monitoring is turned
on using the MonitorTag property,
OnNetworkVariableUpdate events will indicate that the host
network variable was updated. The SourceSubnetId and
SourceNodeId properties can then be used to determine
which of the devices on the network updated the host
network variable.
For high performance when using monitor and control, you
can use a permanent or temporary monitor point with a
defined tag for each remote network variable. You could use
the tag to identifiy the network variable source directly,
without having to translate the source subnet/node ID.
Availability Local, full, and lightweight clients.
