Use node[N].reset() or localnode.reset() to reset only one of the nodes. The other nodes
are not affected. The following programming example shows this type of reset operation with code
that is run on node 1.
-- Reset node 1 only.
node[1].reset()
-- Reset the node you are connected to (in this case, node 1).
localnode.reset()
-- Reset node 4 only.
node[4].reset()
Terminating scripts on the TSP-Link system
You can terminate a script that is executing on a TSP-Link system.
To terminate an executing script and return all nodes to local control, send the following command:
abort
This dissolves the master/subordinate relationships between nodes.
You can also abort an executing script and turn off the source outputs on all source-measure units in
the TSP-Link system. To do this, press the OUTPUT ON/OFF switch on any instrument in the system.
Triggering using TSP-Link synchronization lines
The Model 2450 has three synchronization lines that you can use for triggering, digital I/O, and to
synchronize multiple instruments on a TSP-Link
®
network.
Using TSP-Link synchronization lines for digital I/O
Each synchronization line is an open-drain signal. When using the TSP-Link
®
synchronization lines
for digital I/O, any node that sets the programmed line state to zero (0) causes all nodes to read 0
from the line state. This occurs regardless of the programmed line state of any other node. See the
table in the Digital I/O bit weighting topic for digital bit weight values.
Running simultaneous test scripts
Running test scripts simultaneously improves functional testing, provides higher throughput, and
expands system flexibility. You can use TSP-Link and TSP scripting to run simultaneous test scripts.
You can also manage the resources that are allocated to test scripts that are running simultaneously.
In addition, you can use the data queue to do real-time communication between nodes on the
TSP-Link system.
To run test scripts simultaneously, you can set up your TSP-Link network in one of the following
configurations:
• Multiple TSP-Link networks
• A single TSP-Link network with groups
