5.2 PRODUCT SETUP
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.

These messages appear only if the G60 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

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
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).
NOTE
Do not set more than one protocol to use the same
operation of those protocols.
WARNING
d) MODBUS PROTOCOL
!
PATH: SETTINGS PRODUCT SETUP
# MODBUS PROTOCOL
#
The serial communication ports utilize the Modbus protocol, unless configured for DNP operation (see the DNP Protocol
description 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 G60 will respond regardless of the
grammed. For the RS485 ports each G60 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.
