Commissioning

The downloaded CID file is taken into use when SPA-ZC 400 is restarted
automatically .
Normally, the device is reset automatically after the configuration is
downloaded with Communication Engineering Tool (CET) for SPA-ZC 40x.
After downloading the configuration you can check the basic TCP/IP
functionality with the ping command in command prompt:
c:\>ping x.x.x.x.
You can see how the configuration process is progressing from the diagnostic
LEDs. When the SPA-ZC 400 configuration is completed, the green LED is
on.
If the configuration fails, check the error log files from the SPA-ZC 400 file
system. The status and error logs are located in the /log directory. For more
information about maintenance, refer to Chapter 8. Maintenance and service.

Checking Modbus TCP communication

To check the Modbus TCP communication, open the MODBUS/TCP client,
for example Communication Engineering Tool (CET) for the IEC 61850 OPC
Server, then send a Read Holding Registers message querying some Modbus
points supported by the Modbus slave connected to the serial port of
SPA-ZC 400. In the reply you receive the slave's data for those registers.
If you have Modbus Time Synchronization enabled in the SPA-ZC 400
configuration, you see the Modbus communication indicator LEDs blinking
periodically even if the MODBUS/TCP client is not connected.
