these parameters agree with the settings used on the computer or other equipment that is connected to these ports. Any of
these ports may be connected to a computer running EnerVista UR Setup. 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 con-
nected to a DCS, PLC or PC using the RS485 ports.
For each RS485 port, the minimum time before the port will transmit after receiving data from a host can be
set. This feature allows operation with hosts which hold the RS485 transmitter active for some time after
each transmission.

NETWORK
These messages appear only if the C70 is ordered with an Ethernet card.
The IP addresses are used with the DNP, Modbus/TCP, IEC 61580, IEC 60870-5-104, TFTP, and HTTP protocols. The
NSAP address is used with the IEC 61850 protocol over the OSI (CLNP/TP4) stack only. Each network protocol has a set-
ting for the TCP/UDP port number. These settings are used only in advanced network configurations and should normally
be left at their default values, but may be changed if required (for example, to allow access to multiple UR-series relays
behind a router). By setting a different
TCP/UDP PORT NUMBER
for a given protocol on each UR-series relay, the router can
map the relays to the same external IP address. The client software (EnerVista UR Setup, for example) must be configured
to use the correct port number if these settings are used.
When the NSAP address, any TCP/UDP port number, or any user map setting (when used with DNP) is changed, it
will not become active until power to the relay has been cycled (off-on).
Do not set more than one protocol to the same
TCP/UDP PORT NUMBER
, as this will result in unreliable opera-
tion of those protocols.

MODBUS PROTOCOL
The serial communication ports utilize the Modbus protocol, unless configured for DNP or IEC 60870-5-104 operation (see
descriptions below). This allows the EnerVista UR Setup software to be used. The UR operates as a Modbus slave device
only. When using Modbus protocol on the RS232 port, the C70 will respond regardless of the
MODBUS SLAVE ADDRESS
pro-
grammed. For the RS485 ports each C70 must have a unique address from 1 to 254. Address 0 is the broadcast address
which all Modbus slave devices listen to. Addresses do not have to be sequential, but no two devices can have the same
address or conflicts resulting in errors will occur. Generally, each device added to the link should use the next higher
address starting at 1. Refer to Appendix B for more information on the Modbus protocol.
Changes to the
MODBUS TCP PORT NUMBER
setting will not take effect until the C70 is restarted.
