CX-Compolet
●
Read and write I/O memory in the PLC, change the
operating mode, read error logs, and perform other
operations.
●
Supports Microsoft Visual Studio.NET 2008.
●
Can be used from Visual Basic.NET and
Visual C#.NET.
●
For the CJ2 with EtherNet/IP functionality, I/O
memory in the PLC can be accessed by using
tag names rather than addresses.
●
Array variable access is possible.
Simply paste to the form and
specify the tags (addresses).
Example
Press the button to read the
value (D0 in this example).
Customers who are
developing VB/VC# programs
including communications
with PLCs
Having to program communications
frame assembly, reception response
interpretation, and monitoring is too
much work.
Having to change communications
processing, e.g., for Ethernet and serial
communications, is too much work.
Handling PLC address changes is
particularly time consuming.
For a block of data of the same data
type, it is too much work to have to
specify the addresses one by one rather
than being able to view them as one
group and access that data as an
element.
Processing such as communications frame assembly is prepared
in advance!
Data is accessed by using tag names rather than by using
addresses, so programming does not have to be changed even if
PLC addresses are changed.
Array variables are supported, so data can be easily specified by
simply changing the element subscript with the same tag name.
After installation, the
OMRON SYSMAC CJ2
Icon will be displayed in
the controls.
Position the SYSMAC
CJ2 Icon in the form.
Arrange the command buttons,
text boxes, etc., in the form.
Set the remote PLC in
the properties.
In the Command Button Code
Dialog Box, enter the PLC tag
name on one line. (The tag
name below is “PV.”)

Note:
The above configurations are only examples. Communications are also possible with PLCs
other than those shown here. For details, refer to page 8.
●
Using the control components provided by CX-Compolet frees the application designers from having to program the communications portions of the
application.
●
Data for device alarms and other data are sent to the applications using non-solicited EtherNet/IP communications events.
●
Standardization is made easy by specifying data using tag names (such as “Alarm A” and “Alarm B”) in the applications.
Read and writes data in memory areas, such as the DM Area or CIO
Area. For example, DM word 100 can be specified by using “D100”
or by using a tag name.
Reads and writes memory, such as consecutive words in the DM
Area or CIO Area. For example, it is possible to specify the data type
(integer, single, etc.) or change the data type (BCD, BIN, SBIN).
Supported
