PanelView 1200 Terminal Functions
Chapter 2
2-2
With the optional Remote Keyswitch Assembly, you can access the Mode
Select Keyswitch and RS-232 port from the front of the rack where the
PanelView 1200 terminal is mounted.
For more information on the Remote Keyswitch Assembly, see the
instruction sheet supplied with that option.
There are two types of faults: major faults and minor faults.
Major Faults
If the PanelView 1200 terminal detects a major fault, it enters Major Fault
mode, and displays a message in the Major Fault Window, like this:
20201
While in Major Fault mode, the PanelView 1200 terminal cannot control or
monitor PLC controller functions. The operator must correct the problem
and restart the terminal, or switch modes.
In Run mode, the faults logged to the Major Fault Window cannot be
cleared. If the terminal is set to Configuration mode, the Major Faults
detected on power-up will be logged to the Minor Fault Window and can
be cleared from there.
While the PanelView 1200 terminal is in Major Fault mode, it appears as a
faulted rack to the host PLC controller. You can design your PLC program
to monitor the rack fault bits that correspond to the PanelView 1200
terminal’s rack assignments, and to respond whenever these bits indicate
that the terminal isn’t operating or communicating properly. See your PLC
controller and I/O scanner user’s documentation for details on how to use
the rack fault bits.
Minor Faults
If the PanelView 1200 terminal detects any minor faults, it disables normal
input entry and displays a message in the Minor Fault Window, like this:
