Indicates that it is in the normal communication.
LED lighting test is executed from the controller.
MS/NS indicators blink 3 seconds.
The power doesn't supply to NCW-3DHPN.
- Check wirings of the power supply terminal block of NCW-3DHPN.
- Check that the power voltage is within the range of specification.
- Check whether the power supply capacities are enough or not.
The sensor error (SE) occurred.
For more details, refer to "11-3-3".
NCW-3DHPN has the internal error (RDY LED is OFF).
Restart the power supply. Hardware might have a malfunction if the operation is
not back to normal. Thus, replace the NCW-3DHPN.
Communication is available, but a connection is not established.
Check the Ethernet cable is connected with Ethernet portor properly.
The device's GSDML file might be different in the configuration tool setting.
Check whether the GSDML file is selected correctly, and execute the
configuration again.
An error occurs in communicating I/O controller, and the connection is
interrupted.
- The communication band width of the whole network system might be lack.
Reallocate the communication band width of the whole network system
including NCW-3DHPN IO cycle setting by the configuration tool.
- Irregular communication interrupt might have occurred.
Investigate a conceivable cause in the system.
