RS485
Communication interface standard from EIA (Elec-
tronics Industries Association, USA), operating on
voltages between 0V and +5V. RS-485 is more
noise resistant than RS-232C, handles data trans-
mission over longer distances, and can drive more
receivers.
RTC
Real Time Clock
Integrated clock function in devices used to gen-
erate time and date information if a remote clock
system is not present
Software Local
A Control Access term describing that the M10X
accepts its commands from the hardwired inputs
as a result of either the PCS or MView passing the
Control Access Authority to Soft-Local.
Note: Does not require the hardwired local input
to be set to true.
SNTP
Simple Network Time
Protocol
A protocol used for time synchronization in Con-
trol Network through Ethernet
Switchgear Bus Net-
work
Term used to describe the internal switchgear
communication network, between Digital Gate-
way
and M10X
TCP/IP
Transmission Control
Protocol / Internet
Protocol
TCP/IP is a high-level connection oriented, relia-
ble, full duplex communication protocol devel-
oped for integration of the heterogeneous sys-
tems.
Trip
A consequence of an alarm activated or an exter-
nal trip command from another device to stop the
motor or trip the circuit breaker.
UTC
