Section 9A
Operator Interface
9A-14
Use the removable operator panel on controls installed in locations where
operator/machine interface is not needed often and it is practical for one
operator panel to be transported from control to control when necessary.
The 9/Series removable operator panel allows the connection and
disconnection of the operator panel from the control while the control is
running. This connection/disconnection takes place without any
interruption to control operation and requires no reconfiguration of the
control.
This functionality is made available through the installation of a separate
operator panel interface assembly installed in the 9/Series I/O ring. This
interface assembly allows the removable operator panel to be attached or
detached from the 9/Series I/O ring without physically breaking the I/O
ring. You must install an interface assembly in the 9/Series I/O ring
wherever you intend to attach a removable operator panel.
All connections between the 9/Series controller and the removable operator
panel are made through a single cable. This cable provides all necessary
communications to the 9/Series control (I/O ring interface for the
keyboard, video signal, and power).
