TSP-Link system status

®
TSP-Link is not available on the Models 2604B/2614B/2634B.
The TSP-Link
system can be expanded to include up to 32 TSP-enabled instruments. In a TSP-Link system, one
node (instrument) is the master and the other nodes are the subordinates. The master can control the
other nodes (subordinates) in the system. See
for details about the TSP-Link system.
The system summary registers, shown in the
page E-6) and the
nodes in the TSP-Link system. A status event that occurs at a subordinate node can generate an
SRQ (service request) in the master node. After detecting the service request, your program can then
branch to an appropriate subroutine that will service the request. See
(SRQ) (on page E-15) for details.

Status model configuration example

In this example, a current limit (compliance) event in SMU A or B of node 15 will set the RQS bit of
the Status Byte of the master node. The commands to configure the status model for this example
are provided in
When a current limit (compliance) condition occurs in SMU A or B of Node 15, the following sequence
of events will occur:
•
Node 15: Bit B1 or B2 of the Measurement Event Current Limit Summary Register sets when the
current limit (compliance) event occurs.
•
Node 15: Bit B1 (ILMT) of the Measurement Event Register sets.
•
Node 15: Bit B0 (MSB) of the Status Byte sets.
•
System Summary Registers: Bit B1 (Node 15) of the System Summary Register 2 sets.
The System Summary Registers are shared by all nodes in the TSP-Link system. When a bit in a
system register of node 15 sets, the same bit in the master node system register also sets.
•
System Summary Registers: Bit B0 (Extension) of the System Summary Register sets.
•
Master Node: Bit B0 (MSB) of the Status Byte sets.
•
Master Node: With service request enabled, bit B6 (RQS) of the Status Byte sets. When your
program performs the next serial poll of the master node, it will detect the current limit event and
can branch to a routine to service the request.
