setting is set to 15. Note that these settings are the default values of the deadbands. P_ME_NC_1 (parameter of measured
value, short floating point value) points can be used to change threshold values, from the default, for each individual
M_ME_NC_1 analog point. Whenever power is removed and re-applied to the N60, the default thresholds are in effect.
The setting decides whether multiple client connections are accepted or not. If redundancy is set to Yes,

two simultaneous connections can be active at any given time.
— To close the port, set the port number to 0. The change takes effect when the N60 is restarted.
IEC TCP PORT NUMBER
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.

The N60 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to
which the N60 can connect. A maximum of two simultaneous connections are supported at any given time.

The N60 is provided with optional IEC 60870-5-103 communications capability. This feature is specified
as a software option at the time of ordering. See the Order Codes section in chapter 2 for details.
IEC 60870-5-103 is a companion standard to the IEC 60870-5 suite of standards for transmission protocols. It defines
messages and procedures for interoperability between protection equipment and devices of a control system in a
substation for communicating on a serial line.
The IEC 60870-5-103 protocol is enabled when the
is set to IEC 60870-5-103.
The IEC 60870-5-103 is an unbalanced (master-slave) protocol for coded-bit serial communication, exchanging
information with a control system. In the context of this protocol, the protection equipment is the slave and the control
system is the master. The communication is based on a point-to-point principle. The master must be able to interpret the
IEC 60870-5-103 communication messages.
The UR implementation of IEC 60870-5-103 consists of the following functions:
