Serial Communications Unit Specific Settings
Serial Communications unit specific software switches settings can only be set for CS/CJ/CP series PLCs.
A Serial Communications unit Software Switches dialog includes a General tab described previously.
The Port 1 tab and Port 2 tab are identical. Settings can be specified for the Format field, Mode field and
Hardware field.
Displaying Unit Error Log in the IO Table
By selecting a CPU Bus Unit or Special IO Unit in the IO table tree and clicking the right mouse button to select
the Unit Error Log Menu, the error log for the selected Unit can be displayed (CX-Programmer Ver. 4.0 or later).
IO Table Management
Changes made to an IO Table can be done by simply editing particular fields in the table. Basic information can be
changed by displaying the configuration, selecting the rack or unit that needs to be changed and editing or
selecting the new IO address or configuration information.
All slot allocations in the IO Table can be cleared. Select Clear from the Options menu.
An IO Table unit in the PLC’s Registered IO Table in the PLC can be deleted. Use the following procedure to
delete an IO Table Unit.
1, 2, 3… 1. Highlight the rack/unit in the IO Table to be deleted.
2. Click the right-mouse button and select Delete .
The CX-Server IO Table component can be examined to determine if it has a valid configuration. To check an IO
Table, select the
Check option from the Options menu. A message is displayed indicating whether the operation
was successful or not.
The CX-Server IO Table component can compare the local IO Table on the PC with the CX-Server project
settings and displays any differences or errors. Select the
Compare with Project option from the Options menu.
PC to PLC Communications
The IO Table component permits the transferring of data to and from the PLC and allows comparisons to be made
between data stored on the PC and the PLC.
Note: If the CX-Programmer is Ver. 6.0 or later and the PLC is a CS/CJ/CP-series PLC, the
Special I/O Unit and CPU Bus Unit parameter settings can be transferred as well as the
I/O table.
Transfer an IO Table from a PLC
The Transfer from PLC option loads the Registered Table into the CX-Server IO Table, replacing the currently
displayed setup. The IO Table can also be part of a general transfer which may, for example, include transferring
program and memory data from the PLC. Use the following procedure to transfer an IO Table from the PLC.
1, 2, 3… 1. Ensure the PLC is online before activating the IO Table component.
2. Select Transfer from PLC from the Options menu to transfer an IO Table from the PLC.
The IO Table component is refreshed with the details from the PLC.
Note: If only I/O Table is selected and only the I/O tables are uploaded from the actual PLC to
the computer, the settings in the Special I/O Units or CPU Bus Units on the computer
will be initialized. To maintain the same settings, save the Special I/O Unit or CPU Bus
Unit settings to a file by right-clicking the Unit in the I/O table and selecting Save
Parameters from the pop-up menu. Then, after uploading the I/O tables, read the
settings back from the file by right-clicking the Unit in the I/O table and selecting Load
Parameters from the pop-up menu.
