Within a given link, there may be one or more linkset nodes. Each linkset encompasses all the traffic between two endpoints in a link.

For '''master''' link types of of master/slave protocols (for example [[SHIP:Protocols#Modbus_Master_ASCII|MODBUS_MASTER_ASCII]]) you may want to address multiple slaves on the channel.  Each slave would be identified by a linkset with the slave ID set appropriately.

Child Nodes

The following nodes are permitted to exist within this node:

Properties

Property Name Description
name A unique linkset name within the link
id Some protocols require the endpoint to have an ID number assigned
channel A port name (e.g. UART0)

Examples

Adding two linksets to the example in link reference:

Example link with two linksets

In this example, our GUI is acting as a Modbus Slave attached to UART0, potentially one of many on the communications channel. This physical channel could be, for instance, a multi-drop RS485 network with many slaves of which our SIM is only one. Our GUI, because it has the two linksets at ID #1 and #13 created, will respond as if it were two of those slaves on the network.
