Ethernet interface

The 10/100Base-T Ethernet interface is configured as a Modbus RTU slave. The Ethernet
port has the following characteristics.
• Configuration: setup using IP address, subnet mask, and gateway address.
• Supported Modbus function codes: 3, 4, 5, 6, and 16.
• Supports time/date synchronization via the Network Time Protocol (NTP).
• Ethernet port 502.
• Supports a maximum of 5 virtual connections.
The Ethernet interface has the same memory map layout as the serial Modbus RTU
interface.
Network Time Protocol is enabled if the NTP address is non-zero and the source is
detected.
Once connected to the source, the clock is updated every 30 seconds.
If the IP address of the relay is changed for any reason, the relay must be powered down
then restarted in order for the new IP address to take effect.
