Omron NX102 series User Manual

6 Process Data Communications and SDO Communications
6-16
NJ/NX-series CPU Unit Built-in EtherCAT Port User’s Manual (W505)
If the NJ/NX-series CPU Unit detects a major fault level Controller error, all slave outputs will retain the
process data values from before operation stopped in Operational state. Then the slaves will move to
Safe-Operational state and the slave settings will control the slave outputs. The inputs from the slaves
will retain the process data values from before operation stopped. Message communications are con-
tinued.
*
When a major fault level Controller error occurs, the values of the variables are not output to the slaves
even if they are initialized. The slave settings will control the slave outputs.
* The following errors may occur when the slave enters to the Safe-Operational state.
• Slave Application Error
• Slave Initialization Error
The formula and the maximum time required for all the slaves to enter Safe-Operational state and for
the output to reach to the value set from the slave settings are shown below. This formula applies to
only OMRON slaves.
