When Compare And Merge With Actual Network Configuration Dialog Box Is Not Displayed - Omron Sysmac NJ Series User Manual

5 Setting Up EtherCAT Communications with the Sysmac Studio
Additional Information
• In the following cases, the Compare and Merge with Actual Network Configuration Dialog
Box is not displayed. Refer to 5-6-3 When Compare and Merge with Actual Network
Configuration Dialog Box Is Not Displayed on page 5-32 to remove the cause of the error,
and perform the compare and merge operation.
a) The slave node address settings are not correct on the actual network.
b) The communications cable is not wired correctly.
c) More than the maximum number of slaves are connected.
In addition, if an EtherCAT Frame Not Received (842E0000 hex) event occurs, refer to the
NJ/NX-series Troubleshooting Manual (Cat. No. W503) to remove the cause of the error, and
perform the compare and merge operation.
• After you execute the Compare and Merge with Actual Network Configuration and even
several tens of seconds has passed, if slaves that are connected on the actual network con-
figuration are not displayed in the Compare and Merge with Actual Network Configuration
Dialog Box, refer to 5-6-4 When Slaves on Actual Network Configuration Are Not Displayed
on page 5-39 to remove the cause of the error, and perform the compare and merge opera-
tion.
• After the operation to compare and merge with the actual network configuration is completed,
if there is a ring topology in the network configuration on the Sysmac Studio, refer to Compo-
nents of the Ring Topology on page 4-5 to check that the appropriate slaves are connected.
• When the compare and merge operation is executed for the actual network configuration, the
synchronization between the Sysmac Studio and the Controller is lost. Synchronize the Sys-
mac Studio and Controller before you perform any online operations for the slaves.
Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for information on
synchronization.
• For project unit version 1.40 or later, if the synchronization between the Sysmac Studio and
the Controller is inconsistent, you may not be able to obtain the module configuration infor-
mation on MDP-compatible slaves. Refer to A-3-5 Settings for MDP-compatible Slaves from
Other Manufacturers on page A-27 for information on MDP-compatible slaves.
If you failed to obtain the module configuration information for MDP-compatible slaves, you
can obtain the information by the following steps.
1. Set the Module config send method parameter for the MDP-compatible slaves to Do
not send and perform synchronous transfer.
2. Perform the compare and merge operation.
5-6-3 When Compare and Merge with Actual Network Configuration
Dialog Box Is Not Displayed
If comparison between the network configuration on the Sysmac Studio and the actual network config-
uration cannot be preformed, an error message is displayed. Take appropriate measures according to
the displayed error message and then compare the network configuration on the Sysmac Studio and
the actual network configuration again.
When Slave Node Address Settings Are Not Correct
If the slave node address settings are not correct, the following error message is displayed. Write the
slave node addresses or reset the node addresses using the hardware switches for the slaves dis-
played in the message, and then compare the network configuration on the Sysmac Studio and the
actual network configuration again. Refer to 2-2 Setting the Node Addresses of the EtherCAT Slaves
on page 2-9 for how to write the slave node addresses or reset the node addresses using the hard-
ware switches.
