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 T35 is ordered with an Ethernet card. The
settings allow internal self-test targets to be triggered when either the Primary or Secondary ethernet link
SEC LINK MONITOR
status indicates a connection loss. When both channels are healthy, the primary Ethernet link will be the active link. In the
event of a communication failure on the primary Ethernet link, the secondary link becomes the active link until the primary
link failure has been rectified.
The IP addresses are used with DNP/Network, Modbus/TCP, MMS/UCA2, IEC 60870-5-104, TFTP, and HTTP protocols.
The NSAP address is used with the MMS/UCA2 protocol over the OSI (CLNP/TP4) stack only. Each network protocol has
a setting for the
TCP/UDP PORT NUMBER
mally be left at their default values, but may be changed if required (for example, to allow access to multiple URs behind a
router). By setting a different
same external IP address. The client software (URPC, 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

# 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 URPC Setup software to be used. The UR operates as a Modbus slave
device only. When using Modbus protocol on the RS232 port, the T35 will respond regardless of the
programmed. For the RS485 ports each T35 must have a unique address from 1 to 254. Address 0 is the broad-
