If your system uses
more banks
, follow these steps.
a. Install a 1769-CR
x
Compact I/O communication bus expansion cable
at the right end of the
local bank
.
b. Connect the 1769-CR
x
cable to the additional bank as necessary.
That is, how you connect to the first extra bank—on the right or left
side of the bank, determines the expansion cable that is installed at the
end of the local bank. See

connect a local bank to extra banks.
c. Complete the installation of the remaining banks in your system.
The following example shows example systems with local expansion
modules included.
