7-2-3 Online Editing
The Online Editing function is used to add to or change part of a program in a
CPU Unit directly from the Programming Devices when the CPU Unit is in
MONITOR or PROGRAM mode. Additions or changes are made one instruc-
tion at a time for the Programming Console and one or more program sections
at a time from the CX-Programmer. The function is thus designed for minor
program changes without stopping the CPU Unit.
Online editing is possible simultaneously from more than one computer run-
ning the CX-Programmer as well as from a Programming Console as long as
different tasks are edited.
