localnode.ACCESS_FULL
Usage
accessType = localnode.access
localnode.access = accessType
The type of access:
• Full access for all users from all interfaces: localnode.ACCESS_FULL
• Allows access by one remote interface at a time with logins required from
other interfaces: localnode.ACCESS_EXCLUSIVE
• Allows access by one remote interface at a time with passwords required on
all interfaces: localnode.ACCESS_PROTECTED
• Allows access by one interface (including the front panel) at a time with
passwords required on all interfaces: localnode.ACCESS_LOCKOUT
Details
When access is set to full, the instrument accepts commands from any interface with no passwords required.
When access is set to exclusive, you must log out of one remote interface and log into another one to change
interfaces. To use another interface, log out of the present interface before logging into the new interface. You do
not need a password with this access.
Protected access is similar to exclusive access, except that you must enter a password when logging in.
When the access is set to locked out, a password is required to change interfaces, including the front panel
interface.
Under any access type, if a script is running on one interface when a command comes in from another interface,
the command is ignored and the message "Script running from another interface" occurs.
The command *idn? is permitted from any interface in all access types.
Example
localnode.access = localnode.ACCESS_FULL
login admin
logout
Set the instrument access to locked out.
Log into the interface using the default
password.
Log out of the interface.
