Rockwell Automation 2711 PANELBUILDER SOFTWARE USER MANUAL - Manual (Page 263)

PLC Controlled Options
Chapter 9
9-6
If the PLC controller moves an invalid screen number into this address,
PanelView displays an “Invalid Screen” error message.
Data Type can be Binary or BCD.
IMPORTANT: Unexpected terminal operation can occur if the PLC
Controlled Screen Number function is assigned to an input address. You
must assign an output address to this feature for it to function properly.
Enable this option and assign a PLC output address to allow the PLC
controller to trigger a screen print of the current screen.
Assign a single PLC output bit. When the PLC output bit makes a
transition from 0 to 1, the screen displayed on the PanelView terminal will
be printed. The PLC controller must maintain the set bit long enough to
ensure that it is not missed by the PanelView terminal.
IMPORTANT: Only the screen itself will be printed, not pop-up
windows, such as Alarm or Information windows.
About Screen Prints
Screen prints requested by the PLC controller are processed after all data
in the same PLC scan or block transfer file as the request is processed. If a
screen print request is logged in the same scan or file as a request for a
PLC controlled screen change, the screen displayed prior to the requests
will not be printed. Instead, the requested screen will be displayed and then
printed after it has been updated with the first scan of PLC data.
Some graphic characters will not be printed as they appear on the
PanelView terminal screen. Instead:
ISA symbols, bar graphs, outer borders, arcs, diagonals and line
connectors will be replaced by ASCII character 219 decimal (illustrated
below)
the first 32 characters, used for printer control, will be replaced by
ASCII character 254 decimal (illustrated below)
double width/height characters will be replaced by a single normal sized
character and the appropriate number of blanks
Example: The letter A, displayed with double height and width,
occupies an area 2 characters high and 2 characters wide. Once printed,
the A will occupy the top left position leaving the other three characters
blank.
