Register programming example

The command sequence below programs the instrument to generate a service request (SRQ) and set
the system summary bit in all TSP-Link nodes when the current limit on channel A is exceeded.
-- Clear all registers.
status.reset()
-- Enable current limit bit in current limit register.
status.measurement.current_limit.enable = status.measurement.current_limit.SMUA
-- Enable status measure current limit bit.
status.measurement.enable = status.measurement.ILMT
-- Set system summary; enable MSB.
status.node_enable = status.MSB
-- Enable status SRQ MSB.
status.request_enable = status.MSB

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 D-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 D-15) for details.
