Section 15: Status model Model 2601B-PULSE System SourceMeter Instrument Reference Manual
15-26 2601B-PULSE-901-01A April 2020
When a current limit (compliance) condition occurs in node 15, the following sequence of
events occurs:
• 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.
The figure in Status configuration (enable) commands (on page 15-26) demonstrates the flow of
information through the status model of node 15 and the master node.
Status configuration (enable) commands
For the following registers, the commands listed, which are sent from the master node, enable the
appropriate register bits for the status model configuration example.
Node 15 status registers: The following commands enable the current limit events for node 15:
node[15].status.measurement.current_limit.enable = 6
node[15].status.measurement.enable = 2
node[15].status.node_enable = 1
The affected status registers for the above commands are indicated by labels A, B and C (see
following figure).
Master node system summary registers: The following commands enable the required system
summary bits for node 15:
status.system2.enable = 2
status.system.enable = 1
