OMRON
CX-Programmer – Operation Manual
CX-Programmer_Page (

)
Observe the following precautions when using the CX-Net.
•
Do not change the operating mode of the CPU Unit without first
confirming that operation of the controlled system will not be affect.
•
Do not run the user program on the PLC until its operation has been
checked sufficiently.
•
The data link mode (manual setting or automatic setting) and data link
method are determined according to the data link setting in the startup
node. In the startup node, set a data link table in the case of manual
setting and data link automatic setting parameters in the case of
automatic setting. If the settings are incorrect, the data link will not start.
•
Check the following items before starting data links. If incorrect data link
tables or parameters are set, injury may result due to unexpected
operation of the system. Even if the correct data link tables and
parameters have been set, do not start or stop data links before verifying
that there will be no adverse influence on the system.
(1) Manually Set Data Links
Check the data link tables in each node participating in the data link to
see that they are correct.
Be sure that data link tables are deleted from nodes that are not
participating in the data links.
(2) Automatically Set Data Links
Be sure that the correct DM parameters have been set in the data link
startup node.
•
CPU Bus Units will be automatically restarted when routing tables are
transferred from a Programming Device to the CPU Unit. Resetting is
required to use the new tables. Confirm that restarting the CPU Bus
Units will not adversely affect system operation before transferring
routing tables.
•
When Special I/O Unit or CPU Unit settings are performed in the I/O
Table Window and then transferred from the PLC Memory Window, the
following warning will be displayed if the allocated DM Area/CIO Area
addresses set for Special I/O Units or CPU Bus Units in the I/O Table
Window on the computer overlap with the PLC data table addresses.
Unless the CPU Bus Unit or Special I/O Unit settings have been
previously transferred to the CPU Unit and the allocated DM Area/CIO
Area data in the PLC data table for Special I/O Units or CPU Bus Units is
to be overwritten, always click the No Button, shift the address, and
repeat the transfer procedure.
•
CPU Bus Unit and Special I/O Unit settings are not checked for logical
consistency. Be very careful of the logical consisting of the overall
settings when making any setting that affects other settings, e.g., settings
that enable or disable other settings. Transfer the Special I/O Unit or
CPU Bus Unit settings to the PLC and then start operation, being aware
that any logical inconsistencies may produce unexpected operation.
•
For example, if one setting selects either user settings or default settings
and is set to use the default settings, it will not automatically change to
enable user settings even if the related user settings are made. To use
the user settings, they will have to be enabled manually and specifically
in the setting that selects either user settings or default settings.
