8.5.1.7
Communication checklist
1.
Check the physical connections.
2.
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 DNP3.
3.
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.*.*;).
4.
Ping the unit.
Verify that the IED has been correctly configured to accept messages with the
master's IP address, DNP3 address, and so on.
5.
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.
6.
Install a TCP packet sniffer to see what is happening on the network.
7.
Clear the ARP table.
8.
See the IED's technical manual to determine if the jumpers on the
communication board are correct.
If this protocol does not operate as expected, check that other serial
protocols are not using the COM port also.
DNP3 protocol ignores any parity setting in the COM settings
group; DNP3 is defined as an 8 bit/no parity protocol with a 16-bit
CRC every 16 bytes. This provides better error detection than parity.
