7.1 Introduction
7-2 Printing
This section describes the function keys which appear after pressing the
PRINT (F2) or the XREF (F4) function key. The arrangement of the function
keys in the PRINT hierarchy is shown in Figure 7-1. In addition to the Print
function key, a Print key is available on the VPU200 keyboard. The Print
key is available at any time except during the print operation and will print
the currently displayed screen. The PRINT function key, on the other hand,
appears on the screen of the VPU200 rather than on the keyboard and is
used to print entire groups of related information (such as Memory
Configuration charts, ladder logic programs, and synonyms.)
Note that the mode of operation is important when using the PRINT
function key. The principal difference between the two modes is that
synonyms and comments can only be printed in the Offline mode. All other
categories may be printed regardless of the mode of operation.
