Step 4: Check the state of the TSP-Link system
Reference
The
tsplink.state
TSP-Link reset routine was completed successfully. The returned value
indicates that the reset was successful for all instruments (nodes) in the system.
The value
A few typical reasons for a reset failure include the following:
•
•
•
Programming example – After assigning node numbers to the instruments in the
system, the following command checks the state of the TSP-Link:
print(tsplink.state)
If the reset is successful,
to all nodes is established.

Accessing resources of TSP-Link nodes

After a successful TSP-Link reset, the node and localnode variables can be
used to access resources of any node in the system.
Using node[N]
The node[N] variable (where N = 1 to 64 ) is used to send a command to any
node in the system. The node can be the Master or a Slave. Examples:
node[4].smua.reset()
node[1].smua.reset()
Using the alias (localnode)
The variable localnode is an alias for node[N] , where N is the node number of
the Master.
For example, assume that Node 1 is the Master in a TSP-Link system. To send a
command to Node 1, you can use node[1] or localnode as follows:
node[1].smua.reset()
localnode.smua.reset()

offline
Two or more instruments in the system have the same node number.
There are no other instruments connected to the unit performing the reset.
One of the units in a properly connected system isn't powered on.
