When expanding your system, always add the new bus units to the topmost tier on the right.
Otherwise, the slot numbers on the right of the new bus units will be changed, which requires
address changes in your control program.
Note
After every expansion, check to make certain that the addressing used in the control
program is the same as that in the actual configuration.
