Using the Copy Configuration Feature
Once a Remote I/O Scanner has been entered into the PLC configuration, it can be
copied to any other location on the bus.  With the cursor at the module to be copied,
press the Copy key.  Move the cursor to the intended location for the copy and press
the Enter key.
When the configuration of a Remote I/O Scanner is copied, the Logicmaster 90–70
software automatically increments the Remote Drop ID and the Reference Addresses
for the copy to the next ones available.  The configured lengths remain the same.  For
instance, if the first Remote I/O Scanner has been assigned to use 32 bits of %I memory,
the duplicated configuration of the next Remote I/O  Scanner would also initially
assign %I memory the length of 32 bits.  Like any of the other configurable parameters,
this could be changed in the copied configuration.
When using the Copy feature, it is important to check reference limits.  Once a
reference type limit is reached, the Logicmaster software stops incrementing the
reference address, and on successive copies the address ranges will overlap.
Using Reference View from the PLC Program Folder 
In the PLC program folder, the Reference View function of Logicmaster 90–70 shows
the Remote I/O Scanner as a single module.  Individual I/O modules in a remote drop
do not appear.  In the example below, the two output modules listed are in rack 1, slots
3 and 4.  They are NOT modules in the remote drop.  Notice that their reference
addresses are not within the range assigned to the Remote I/O Scanner.

The display shows the references assigned to the Remote I/O Scanner for the selected
memory type.  In this example, the Remote I/O Scanner is assigned references
%Q00001 to %Q00064.  It is within this range that the PLC will supply discrete outputs
to modules in the remote drop.
Step 4: Store the Configuration to the PLC
After creating or editing a program folder, it can be stored to the PLC at any time. Use
the Utility functions to store a program folder to the PLC, as described in the
Logicmaster 90–70 User’s Manual.
