Using the reset() command
Most TSP-Link
®
system operations target a single node in the system, but the reset() command
affects the system as a whole by resetting all nodes to their default settings:
-- Reset all nodes in a TSP-Link system to their default state.
reset()
Using the reset() command in a TSP-Link network differs from using the tsplink.reset()
command. The tsplink.reset() command reinitializes the TSP-Link network and will turn off the
output of any TSP-linked instrument; it may change the state of individual nodes in the system.
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()
A TSP-Link
®
reset command populates the node table. Each instrument in the system corresponds to
an entry in this table. Each entry is indexed by the node number of the instrument. The variable
node[N] (where N is the node number) is used to access any node in the system. For example, node
1 is represented as entry node[1] in the node table.
Each of these entries is a table holding all the remote commands shared by the corresponding
instrument. Source-measure unit (SMU) A on node 1, therefore, could be accessed as
node[1].smua.
Using the abort command
An abort command terminates an executing script and returns all nodes to local operation (REM
indicators turn off). This dissolves the master/subordinate relationships between nodes. To invoke an
abort operation, either send an abort command to a specific node or press the EXIT (LOCAL) key
on any node in the system.
You can also perform an abort operation by pressing the OUTPUT ON/OFF control on any node. The
results are the same as above, with the addition that all outputs in the system are turned off.
Triggering with TSP-Link
The TSP-Link
®
expansion interface has three trigger lines that function similarly to the digital I/O
synchronization lines. See Digital I/O (on page 2-28) and Triggering for more information.
