PRODUCT SETUP
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 L60 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 L60 maintains two
sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the L60 at one
time.
The
IEC ------- DEFAULT THRESHOLD
M_ME_NC_1 analog data. These settings group the L60 analog data into types: current, voltage, power, energy, and other.
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 L60 when any current values change by 15 A, the
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 L60, the default thresholds are in effect.
The
IEC REDUNDANCY
two simultaneous connections can be active at any given time.

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