LPTLib commands
addcon
This command adds connections without clearing existing connections.
Usage
int addcon(int
exist_connect
, int
connect1
, [
connectn
, [...]] 0);
exist_connect
A pin number or instrument terminal ID; this instrument or terminal may have been,
but is not required to have been, previously connected with the
addcon
,
conpin
,
or
conpth
command
connect1
A pin number or an instrument terminal ID
connectn
A pin number or an instrument terminal ID
Details
The S530/S540 has an I-V matrix. The
addcon
command can be used to make additional
connections on this matrix. I-V connections are direct connections.
When used with the I-V matrix, the
addcon
command connects every item in the argument list and
there is no real distinction between the
exist_connect
parameter and the rest of the connection
list. When using the
addcon
command with the I-V matrix, the command functions like the
conpin
command, except previous connections are never cleared.
The value
-1
is ignored by the
addcon
command and is considered a valid entry in the connection
list, as is the
exist_connect
parameter. There must be at least two parameters with a value other
than
-1
.
Matrix errors are generated if the following condition is detected:
•
A dangerous connection is detected such as connecting a source-measure unit (SMU) high
terminal directly to ground.
Before making the new connections, the
addcon
command clears all active sources by calling the
devclr
command.
