Keithley 2601 Reference Manual

Attribute Automatic power line frequency detection control.
Usage flag = localnode.autolinefreq -- Read auto line frequency detection setting.
localnode.autolinefreq = true -- Enable automatic line frequency detection
on power-up.
Remarks • When this attribute is set to true, the power line frequency is detected
automatically the next time the Series 2600 powers up.
• After the power line frequency is automatically detected at power-up, the
localnode.linefreq attribute will be set automatically to 50 or 60.
• If the localnode.linefreq attribute is explicitly set,
localnode.autolinefreq will be automatically set to false.
• When used in an expanded system (TSP-Link), localnode.autolinefreq is sent to the
remote master node only.
• Use node[N].autolinefreq (where [N] is the node number) to
send the command to any node in the system. See Section 9 for details on
TSP-Link.
• This command is compatible with firmware version 1.2.0 and later.
Also see localnode.linefreq
Example Disable automatic power line frequency detection:
localnode.autolinefreq = 0

localnode.autolinefreq
localnode.execute
Function Use this function to start test scripts on a remote node.
Usage node[N].execute (myscript)
myscript Replace the custom variable myscript with the variable
name or the source code.
Remarks • Only the master node can issue the execute command to a remote node.
• You cannot use the execute command to run test scripts on the master node.
Example
-- Runs script code stored in the custom variable sourcecode.
node[N].execute (sourcecode)
-- Runs script code in a string constant.
node[N].execute ("x=5")
-- Runs a test script that was loaded into memory.
node[N].execute (myscript.source)
localnode.getglobal
Function This function returns the value of a global variable.
Usage
value = node[N].getglobal(name)
name The name of the global variable.
value The value of the global variable.
N The number of the remote node.
Remarks • Use this function to retrieve the value of a global variable from a remote node.
• Do not use this command to retrieve the value of a global variable from a local node.
Example -- Retrieves and outputs the value of the global variable named meas_val from node 5.
print(node[5].getglobal(“meas_val”))
