TSP-Link nodes
Each instrument or enclosure attached to the TSP-Link expansion interface is called a node. Each
node must be identified with a unique node number. This identification is called a TSP-Link node
number.
An individual node is accessed as
node[
N
]
, where
N
is the node number assigned to the node. You
can access all TSP-accessible remote commands as elements of the specific node. The following
attributes are examples of items you can access:
•
node[
N
].model
: The product model number of the node.
•
node[
N
].version
: The product version of the node.
•
node[
N
].serialno
: The product serial number of the node.
Assigning node numbers
Each Model 2461 instrument is initially assigned as node 2. You can assign node numbers from 1 to
64. However, the system can only include 32 physical nodes.
The node number for each instrument is stored in its nonvolatile memory and remains in storage
when the instrument is turned off.
You can assign a node number to an instrument using the front panel or by using a remote command.
To assign a node number using the front panel:
1. Press the
MENU
key.
2. Under System, select
Communication
. The SYSTEM COMMUNICATIONS window opens.
3. Select the
TSP-Link
tab.
4. Next to Node, set the TSP-Link address for this instrument.
To assign a node number using a remote command:
Set the
tsplink.node
attribute of the instrument:
tsplink.node =
N
Where
:
N
= 1 to 64
To determine the node number of an instrument, you can read the
tsplink.node
attribute by
sending the following command:
print(tsplink.node)
The above
command outputs the node number. For example, if the node number is 1, a
1
is
displayed.
