makegetter functions
These functions are used to set and retrieve a value for an attribute.
localnode.showerrors
Attribute Automatic display of errors.
Usage
errormode = localnode.showerrors -- Reads show errors state.
localnode.showerrors = errormode -- Writes show errors state.
errormode Set to 0 or 1.
Remarks
• If this attribute is set to 1, for any errors that are generated, the unit will automatically
display the 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
Section 9 for details
on TSP-Link.
Details See “errorqueue functions and attribute”
Also see localnode.prompts
Example Displays errors:
localnode.showerrors = 1
makegetter
Function Creates a function to set the value of an attribute.
Usage
getter = makegetter(table, attributename)
table Read-only table were the attribute is located.
attributename The string name of the attribute.
getter Function that returns the value of the given attribute.
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.
