Buswide access allows communication between an XI581/2 and an Excel controller
that is not directly connected to the XI581/2. Communication can include reading
from and writing to the remote controller as well as receiving alarm status
information.
For example, an XI581/2 on an Excel 500 Controller can log in to an Excel 100
Controller that connects to the same system bus as the Excel 500 Controller.
