It may take some time to display the check result.
The master side is checked to see if it can accept communication when the slave is connected and the check result is displayed.

INIT
CANopen module is not initialized yet.
RESET
CANopen module is performing a reset.
PREPARE NET INIT
CANopen module carries out a check of the slave assignments.
NETWORK RESET
The CANopen network is reset by NMT command. Resets all communication slaves.
NETWORK WAIT
The CANopen module waits for a certain time so that the modules can execute that Reset communication command.
BOOTING UP
The CANopen module initializes the individual slaves on the network.
CLEAR
The CANopen network is scanned. The CANopen module can be started.
Operational Slaves
The CANopen network is operational.
Preoperational Slaves
The CANopen network is preoperational.
Fatal error
A fatal error has occurred on the network. The CANopen module will get reset.
A fatal error occurred in an error code. Check the error details displayed in the lower left of the screen and take the appropriate action according to the following:
T.8.6 Errors displayed when CANopen is used
MISSING MAND. SLAVE

Communication status.
The different radio buttons shows the communication status of CANopen Master.
CAN controller overrun
CAN controller overrun has occurred.
CAN Bus off
BUS OFF detected by CAN Controller.
CAN controller error
CAN controller is in error state. Check the connection devices (for example, connector and cable) and then reset the CANopen module. After confirmation, reset the CANopen master display unit.
CAN ctrl. Left error state
CAN controller has left the error state.
Tx LP Queue overrun
An overrun of the low priority transmit queue has occurred. Low priority transmit queue is for heartbeat, node guarding and SDO transfer.
Tx HP Queue overrun
An overrun of the high priority transmit queue has occurred. High priority send queue is for TPDOs, NMT, commands, SYNC and EMCY messages.
Queue overrun (RXLP)
An overrun of the low priority receive queue has occurred. Low priority receive queue is for heartbeat, node guarding and SDO transfer.
Rx HP Queue overrun
An overrun of the high priority receive queue has occurred. High priority receive queue is for RPDOs, NMT, commands, SYNC and EMCY messages.
Optional module error
At least one optional or unexpected module does not correspond to the expected network configuration. Reset the network. If this error reoccurs despite the network reset, review the project settings and slave configuration.
Mandatory module error
At least one mandatory module does not match the network configuration. Review the project settings and slave configuration.
Network operational
At least one module (besides the GP/LT) is operational.
