4.6.9 Setting transfer areas where an S10mini and an S10V are intermixed
This section describes how to configure and set the addition of an S10V to a network on which
extend memory has been set as an SD.LINK transfer area by the S10mini. While the SD.LINK
caries out absolute addressing-conscious transfers, simply transferring from S10mini extend
memory to the S10V would not update the corresponding address location in the S10V, because
its addresses associated with S10mini extend memory include ladder program and system table
addresses as well. To work around this inconvenience, the S10mini extend memory addresses
and S10V extend registers are associated with each other to carry out transfers between them.
See the schematic below.

To transfer S10mini extend memory contents to the S10V and transfer S10V extend register
contents to S10mini extend memory, associate the S10V extend registers with S10mini extend
memory in the [S10V] OD.RING/SD.LINK system [Set parameter] window. The operation
illustrated above could be accomplished by filling out the screen as shown in Figure 4-5.
