Warning
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.
Integrated clock function in devices used to gen-
erate time and date information if a remote clock
system is not present
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.
A protocol used for time synchronization in Con-
trol Network through Ethernet
Term used to describe the internal switchgear
communication network, between Digital Gate-
way and M10X
TCP/IP is a high-level connection oriented, relia-
ble, full duplex communication protocol devel-
oped for integration of the heterogeneous sys-
tems.
A consequence of an alarm activated or an exter-
nal trip command from another device to stop the
motor or trip the circuit breaker.
Coordinated Universal Time is the international
time standard. It is the current term for what was
commonly referred to as Greenwich Meridian
Time (GMT). Zero (0) hours UTC is midnight in
Greenwich England, which lies on the zero longitu-
dinal meridian. Universal time is based on a 24-
hour clock.
A warning is defined as status transition from any
state to pre-alarm state to inform in advance be-
fore an alarm level is reached.
