that are mounted on this unit, providing a space saving chassis-less system.
On-line attachment and removal that is essential for continuously operating instrumentation
control and dual bus signals provide high reliability, and at the same time the system has
intelligent functions for response to a variety of signals from the work site so that it can be used in
a wide variety of fields.
