Introduction to PanelView 1200 Operator
Terminals
Chapter 1
1-17
The following options can be controlled by the PLC controller:
PLC Controlled Audio allows the PLC controller to control the
PanelView 1200 terminal’s audio beeper. A PLC bit address is assigned.
When the PLC controller sets this bit, the terminal’s beeper is activated.
This does not interfere with the Alarm Window’s use of the beeper.
PLC Controlled Alarm Relay allows the PLC controller to control the
PanelView 1200 terminal’s alarm relay. A PLC bit address is assigned,
and when the PLC controller sets this bit, the terminal’s alarm relay is
energized. This does not interfere with the Alarm Window’s use of the
relay.
PLC Controlled Alarm Quantity/Accum Time Reset allows the PLC
controller to reset the alarm count and the accumulated time-in-alarm
total. These totals are shown in the Alarm Status screen.
PLC Controlled Screen Number allows the PLC controller to control
which screen is displayed. When the PLC controller puts a screen
number in an assigned address, the PanelView 1200 terminal displays
the screen. This PLC controlled screen change always has precedence
over operator-controlled screen changes, and operator-generated screen
changes are allowed only if the PLC address contains 0.
PLC Controlled Screen Print allows the PLC controller to trigger a
printout of the screen displayed on the PanelView 1200 terminal.
PLC Controlled Time and Date allows the PanelView 1200 terminal
to read the time and date from the PLC controller and set its internal
clock.
PLC Controlled Clear Window clears the alarm window, the alarm
beeper and the alarm relay when a 0 to 1 transition is detected in the
assigned PLC address bit.
PLC Controlled Silence Alarms silences the beeper and deactivates
the alarm relay when a 0 to 1 transition is detected on this bit.
PanelView 1200 terminals can be connected to any Allen-Bradley 1771
Remote I/O Link. Applicable host controllers include almost all
Allen-Bradley Programmable Logic Controllers as well as certain IBM
computers, VME Controllers, and the DEC
Q-Bus
interface.
Newly released Allen-Bradley programmable controllers that are not yet
listed will support PanelView 1200 terminals, as long as they support the
1771 remote I/O.
