• Port 5 (IP address 10.1.2.2) connects to LAN 10.1.2.0/24 and to EnerVista setup
program through Router 2. Router 2 has an interface on 10.1.2.0/24 and the IP
address of this interface is 10.1.2.1.
Configuration
Network addresses:
PRT54IP ADDRESS = 10.1.1.2PRT4 SUBNET IP MASK = 255.255.255.0PRT5 IP ADDRESS =
10.1.2.2PRT5 SUBNET IP MASK = 255.255.255.0
Routing Settings:
IPV4 DEFAULT ROUTE: GATEWAY ADDRESS = 10.1.1.1
STATIC NETWORK ROUTE 1:
– RT1 DESTINATION = 10.1.3.0/24RT1 NET MASK = 255.255.255.0RT1 GATEWAY =
10.1.2.1
Behavior: One static network route was added to the destination 10.1.3.0/24, where a
laptop running EnerVista is located. This static route uses a different gateway (10.1.2.1)
than the default route. This gateway is the address of Router 2, which is "aware" of
destination 10.1.3.0 and is able to route packets coming from the 8 Series device and
destined to EnerVista.
These values specify the maximum and the remaining number of TCP connections still
available for each protocol. Depending on the order code, some protocols may be hidden.
Each time a connection is used, the remaining number of connections decrements. When
a connection is released, the remaining number of connections increments. If no
connection is made over the specific protocol, the number remaining equals the maximum
number available for the specific protocol.
For example, the maximum number of Modbus TCP connections is 5. Once an EnerVista
session is opened on a computer connected to the 8series over Ethernet, the Modbus TCP
status shows 4. If the EnerVista application is closed, the Modbus TCP status shows 5.
The following are the Maximum TCP connections per protocols for the "SE"
communications order code option:
Modbus TCP - Maximum
DNP TCP - Maximum
* With USB or WiFi connections, this number decreases as follows:
• 1 USB or 1 WiFi connection: Modbus TCP - Maximum = 2
• 1 USB and 1 WiFi connection: Modbus TCP - Maximum = 1
The following are the Maximum TCP connections per protocols for the Advanced
communications order code options:
