Makegetter Functions - Keithley 2601 Reference Manual

Section 12: Instrument Control Library
localnode.setglobal
Function Sets the value of a global variable.
Usage
node[N].setglobal (name, value)
name
value
Remarks • Use this function to create a global variable and to assign values to the global variable from a
remote master node.
• Do not use this command to set the value of a global variable on the local node.
Example
node[N].setglobal ("x", 5)
localnode.showerrors
Attribute Automatic display of errors.
Usage
errormode = localnode.showerrors
localnode.showerrors = errormode-- Writes show errors state.
errormode
Remarks • If this attribute is set to 1, the unit will automatically display any generated errors stored in the
error queue, and then clear the queue. Errors will be processed at the end of executing a
command message (just prior to issuing a prompt, if prompts are enabled).
• If this attribute is set to 0, errors will be left in the error queue and must be explicitly read or
cleared.
• When used in an expanded system (TSP-Link), localnode.showerrors is sent to the
remote master node only. Use node[N].showerrors (where N is the node number) to
send the command to any node in the system. See
Details See errorqueue functions and attribute

makegetter functions

These functions are used to set and retrieve a value for an attribute.
makegetter
Function Creates a function to set the value of an attribute.
Usage
getter = makegetter(table, attribute name)
table
attributename
getter
Remarks • This function creates a function that when called returns the value of the attribute. This
function is useful for aliasing attributes to improve execution speed. Calling the getter
function will execute faster than accessing the attribute directly.
• Creating a getter function is only useful if it is going to be called several times.
Otherwise the overhead of creating the getter function outweighs the overhead of
accessing the attribute directly.
Example Creates a getter function called
getlevel = makegetter(smua.source, "levelv")
...
v = getlevel()
When getlevel is called, it returns the value of smua.source.levelv.
