PRODUCT SETUP
The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the N60 over a network. The N60 operates as a
TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file obtained
from the N60 contains a list and description of all available files (event records, oscillography, and so on).
While TFTP is supported, the put function is not for security reasons. For example, you can enter a "get" command but not
a "put" command.

restarted.
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.

IEC 60870-5-104 is a transmission protocol for network access, specifically for communication between a control station
and substation over a TCP/IP network.
The N60 supports the IEC 60870-5-104 protocol. This protocol is enabled when the

connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the N60 maintains two
sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the N60 at one
time.

Each setting represents the default threshold value for all M_ME_NC_1 analog points of that type. For example, to trigger
spontaneous responses from the N60 when any current values change by 15 A, the
