Using the expanded system
Accessing nodes
A TSP-Link reset creates the
node
table. Each unit in the system corresponds to
an entry in this table, indexed by the unit's node number. The
node[N]
variable
(where
N
is the node number) is used to access any node in the system. For
example, Node 1 is represented in the
node
table as entry
node[1]
.
Each of these entries is, in turn, a table, holding all of the logical instruments (and
associated ICL commands) shared by the corresponding unit (see “
for more details). SMU A on Node 1, therefore, could be
accessed as
node[1].smua
.
The
localnode
variable is an alias for
node[N]
, where
N
is the node number of
the Master. For example, if Node 1 is the Master,
localnode
can be used instead
of
node[1]
.
Programming examples
– The following examples show how to access
instruments in the TSP-Link system shown in
• Any of the following three commands can be used to reset SMU A of Node
1 (which, in this example, is the Master). The other nodes in the system are
not affected.
smua.reset()
localnode.smua.reset()
node[1].smua.reset()
• The following command will reset SMU A of Node 4, which is a Slave. The
other nodes are not affected.
node[4].smua.reset()
NOTE
For remote programming, scripts that reside on
Slave nodes are not accessible.
