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.
Operating in
MONITOR mode.
The cycle time will be increased by from one to several cycle times if the pro-
gram in the CPU Unit is edited online in MONITOR mode.
The cycle time for CS1-H, CJ1-H, and CJ1M CPU Units will also be increased
to back up data in the flash memory after online editing. The BKUP indicator
will be lit during this period. The progress of the backup is displayed on the
CX-Programmer. The increases per cycle are listed in the following table.
CPU Unit
CS1 CPU Units pre-EV1
CS1 CPU Units EV1 or later
CS1-H CPU Units
CS1 CPU Units
CJ1-H CPU Units
CJ1M CPU Units
With a CS1-H, CJ1-H, or CJ1M CPU Unit, there is a limit to the number of
edits that can be made consecutively. The actual number depends on the type
of editing that is performed, but the following can be used as guidelines.
CJ1M-CPU@@:
CS1G-CPU@@H/CJ1G-CPU@@H: 160 edits
CS1H-CPU@@H/CJ1H-CPU@@H: 400 edits
