PT Program Generator (PPG) v5.0

The virtual display maintains the latest lines of data once all lines of the virtual
display are full. The oldest lines of data are “pushed off the top” as new data is
added at the bottom.

Defining Program Flow

After you create all the nodes, connect the program pieces together using

Link

Nodes

to define the flow of the program.

Links are shown on the PPG display with arrows which point from one step to
the next. Some nodes will have multiple entry and exit points. For example, a

Copy

node can have either one or two exit points. You may choose to have

your application go to a

Display

node if an error occurs or, if the copy opera-

tion is successful, to continue on to a

Menu

node.

For information on the mechanics of creating, modifying and deleting Links,
refer to

Refer to

Sending and Receiving Files

The final step in using PPG is to transfer the applications you have created to
the Falcon PT40. Refer to

PT40 Communication on page 89

for more information

on sending and receiving files.

is a flow chart showing the application generation, data flow,

file transfer process used when you create custom files with PPG

and down-

load them to your PSC Falcon PT40 from a PC.
