Troubleshooting

Check the physical connections.

After the settings are changed, allow them to be stored in NVRAM (!S on

LHMI).

Reboot the unit to allow the setting changes to take effect in DNP 3.0.

If the WHMI connection is missing, enable the IED's WHMI setting and prevent

the Web browser from attempting to use a proxy Internet Options/

Connections/LAN Settings/Advanced/Exceptions (for example

192.168.*.*;).

Ping the unit.

Verify that the IED has been correctly configured to accept messages with the

master's IP address, DNP 3.0 address, and so on.

Use the LHMI to enable the WHMI configuration if a ping response is received

from the unit but the WHMI does not respond.

5.1. Clear the browser of cached pages.

5.2. Logout and log back in.

Install a TCP packet sniffer to see what is happening on the network.

Clear the ARP table.

See the IED's technical manual to determine if the jumpers on the

communication board are correct.

DNP 3.0 protocol ignores any parity setting in the COM settings

group; DNP 3.0 is defined as an 8 bit/no parity protocol with a 16-bit

CRC every 16 bytes. This provides better error detection than parity.
