Series 2600A System SourceMeter® Instruments Reference Manual

Appendix C: Status Model

Messages in the Error Queue include a code number, message text, severity, and TSP-Link node 
number. The messages are listed in 

Table A-2

.

TSP-Link system status

The TSP-Link is an expansion interface that allows the instruments to communicate with each 
other. The test system can be expanded to include up to 64 TSP-Link-enabled instruments. In a 
TSP-Link system, one node (instrument) is the Master and the other nodes are the Slaves. The 
Master can control the other nodes (Slaves) in the system. See 

Section 14

 for details on the 

 

TSP-Link.

The system summary registers (shown in 

Figure C-1

 and 

Figure C-2

) are shared by all nodes in 

the TSP-Link system. A status event that occurs at a Slave 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 

Status byte and service request (SRQ)

 

for details. 

Status model configuration example

Figure C-12

 shows an example status model configuration for a TSP-Link system. In this example, 

a current limit (compliance) event in SMU A or SMU 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 

Status configuration (enable) commands

 in this appendix.

When a current limit (compliance) condition occurs in SMU A or SMU 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 System2 Summary Register sets. 

NOTE

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. 

Table C-5

Error queue commands

Error queue command

Description

errorqueue.clear()

Clear error queue of all errors.

errorqueue.count

Number of messages in the error/event queue.

errorcode, message, 

severity, node = 

errorqueue.next()

Request error code, text message, severity, and 
TSP-Link node number.
