OMRON
Replacements can be performed only in the
entire PLC or in the data in the current view.
The setting for the item to be replaced was very
detailed and included bit addresses, address,
values (constants/numbers), mnemonics,
symbols, and I/O comments.
Version 8.3 Upgrade Information
Functionality Improved from Version 8.2 to 8.3
Compatible PLC Models
The functionality improvements are supported for CJ2H CPU Units with unit version
1.2 or later.
TIMER and COUNTER Added as Symbol Data Types
When defining timer numbers and counter
numbers as symbols, the following three different
symbols had to be registered in the symbols
table.
Automatically assigning timer and counter
numbers in ladder programs was not possible.
Force-setting/resetting Bits in EM Area
Bits in the EM Area could be force-set/reset in
CJ2H CPU Units only for specific EM Area banks
for which automatic address assignment was
used.
Searching for Symbol Names and Displaying Usage Locations from Cross-reference Pop-
ups
Searching from cross-reference pop-ups was
possible only for address specifications. (To
search for symbols, you had to click the Browse
button and search for symbol names from the
Symbol Search Dialog Box.)
Previous version (version 8.3)
Previous version (version 8.2)
1.
Timer numbers and counter numbers
specified in instruction operands had to
be defined as NUMBER symbols.
2.
Timer and Counter Completion Flags
had to be defined as BOOL symbols.
3.
Timer and counter present values had
to be defined as CHANNEL symbols.

PART 1: CX-Programmer
New version (version 9.0)
"Programs" has been added to the replacement
range.
Also, the selected circuits can be set as the
replacement range.
Searched objects have been grouped into
addresses, symbol names, mnemonics, and
comments.
New version (version 8.3)
TIMER and COUNTER symbols are supported
so that all of the previous three types of symbols
can be managed as one data type. (TIMER and
COUNTER are supported only by CJ2H CPU
Units with unit version 1.0 or later.)
TIMER: Can be used for 1) the timer number, 2)
the Timer Completion Flag, and 3) the timer
present value.
COUNTER: Can be used for 1) the counter
number, 2) the Counter Completion Flag, and 3)
the counter present value.
Automatic address assignment and layout are
supported for TIMER and COUNTER symbols.
(TIMER and COUNTER are supported only by
CJ2H CPU Units with unit version 1.0 or later.)
New version (version 8.3)
With CJ2H CPU Units with unit version 1.2 or
later, PLC • Memory Allocate • EM Memory
Settings can be used to specify the EM Area
banks for which bits can be force-set/reset. (The
first bank is specified and force-setting/resetting
bits is possible in that bank and all banks
following it.) This is called the EM Area force-
setting/resetting function.
New version (version 8.3)
Symbol names can be specified directly in cross-
reference pop-ups to display a list of locations
that use the address of that symbol.
