ports. The faceplate RS232 port is intended for local use and has two options for baud rate. The rear COM2 port is RS485
and has settings for baud rate and parity. It is important that these parameters agree with the settings used on the
computer or other equipment that is connected to these ports. Any of these ports can be connected to a computer
running the EnerVista software. This software can download and upload setting files, view measured parameters, and
upgrade the relay firmware. A maximum of 32 relays can be daisy-chained and connected to a DCS, PLC, or computer
using the RS485 ports. If IEC 60870-103 is chosen as the protocol, valid baud rates are 9600 and 19200 bit/s, and valid
parity is Even.

receiving data from a host. This feature allows operation with hosts that hold the RS485 transmitter active for some time
after each transmission.
5.3.4.3 Ethernet network topology
The N60 has three Ethernet ports. Each Ethernet port must belong to a different network or subnetwork. Configure the IP
address and subnet to ensure that each port meets this requirement. Two subnets are different when the bitwise AND
operation performed between their respective IP address and mask produces a different result. Communication becomes
unpredictable when more than one port is configured to the same subnet.
Example 1
IP1/Mask1: 10.1.1.2/255.255.255.0 (where LAN 1 is 10.1.1.x/255.255.255.0)
