Omron NX Series User Manual

Precautions for Correct Use
• If the node addresses (IP addresses) are not set correctly, you may connect to the wrong
Controller and set incorrect device parameters. Download data only after you confirm that
you are connected to the correct Controller.
•
If incorrect tag data link parameters are set, it may cause equipment to operate unpredictably.
Even when the correct tag data link parameters are set, make sure that there will be no effect
on equipment before you transfer the data.
• When network variables are used in tag settings, a connection error will result if the variables
are not set in the NX-series EtherNet/IP Unit. Before downloading the tag data link parame-
ters, check to confirm that the network variables are set in the NX-series EtherNet/IP Unit.
Check whether the network variable, tag, and connection settings are correct on the
Connection Tab Page and the Tag Status Tab Page as described in 14-6-1 The Network
Configurator's Device Monitor Function on page 14-47.
• If a communications error occurs, the output status depends on the specifications of the de-
vice being used. When a communications error occurs for a device that is used along with
output devices, check the operating specifications and implement safety countermeasures.
• The EtherNet/IP port is automatically restarted after the parameters are downloaded. This re-
start is required to enable the tag set and connection information. Before you download the
parameters, check to confirm that problems will not occur with the equipment when the port is
restarted.
• Make sure that the major CIP revision of the device registered with the Network Configurator
is the same as the major CIP revision of the NX-series EtherNet/IP Unit that you use. If the
major CIP revisions are not the same, the parameters may not be downloaded. To determine
whether downloading is possible, refer to 9-2-3 Registering Devices on page 9-17.
• Do not disconnect the Ethernet cable or reset or turn OFF the power to the NX-series Ether-
Net/IP Unit during the parameter download.
• Tag data links (data exchange) between relevant nodes are stopped during a download. Be-
fore you download data in RUN mode, make sure that it will not adversely affect the control-
led system.
Also implement interlocks on data processing in ladder programming that uses tag data links
when the tag data links are stopped or a tag data link error occurs.
1 Connect the Network Configurator to the network.
