The behavior since release 7.10 is as follows. There is one added static network route to the destination 10.1.3.0/
24, where a computer 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 has knowledge about 10.1.3.0 and is able to route
packets coming from UR and destined to EnerVista.
SHOW ROUTES AND ARP TABLES
This feature is available on the Web interface, where the main menu contains an additional Communications menu and two
submenus:
•
Routing Table
•
ARP Table
The tables outline the information displayed when the two submenus are selected.

PRODUCT SETUP
COMMUNICATIONS
MODBUS PROTOCOL
The serial communication ports utilize the Modbus protocol, unless the port is configured for DNP or IEC 60870-5-103
operation. This allows the EnerVista UR Setup software to be used on the port. The UR operates as a Modbus slave device
only.
When using Modbus protocol on the RS232 port, the C60 responds regardless of the
MODBUS SLAVE ADDRESS
pro-
grammed. For the RS485 port, each device on the serial bus must have a unique slave address from 1 to 254. Address 0
and addresses from 248 and up are reserved by the Modbus protocol specification, and so their use here is not recom-
mended. Address 0 is the broadcast address that all Modbus slave devices listen to. When
MODBUS SLAVE ADDRESS
is set
to 0, the UR accepts broadcast messages, but in compliance with protocol specifications for broadcast messages, never
replies. Addresses do not have to be sequential, but no two devices can have the same address or conflicts resulting in
errors occur. Generally, each device added to the link should use the next higher address starting at 1. When using Modbus
TCP/IP, the client must use the programmed
MODBUS SLAVE ADDRESS
value in the Unit Identifier field. See Appendix B for
more information on the Modbus protocol.
Modbus over TCP/IP can also be used on any of the Ethernet ports. The listening TCP port 502 is reserved for Modbus
communications, and only in exceptional cases when
MODBUS TCP PORT NUMBER
is set to any other port. The
MODBUS TCP
PORT NUMBER
setting sets the TCP port used by Modbus on Ethernet. A
MODBUS TCP PORT NUMBER
of 0 disables Modbus
over TCP/IP, meaning closes the Modbus TCP port. When it is set to 0, use the front panel or serial port to communicate
with the relay.
