IEC type 1+ input Type 1+ digital inputs support sensor signals from mechanical switching devices
such as relay contacts, push buttons (in normal-to-moderate environmental
conditions), three-wire proximity switches and two-wire proximity switches that
have:
a voltage drop of no more than 8 V
a minimum operating current capability less than or equal to 2 mA
a maximum off-state current less than or equal to 0.8 mA
IEC type 2 input Type 2 digital inputs support sensor signals from solid state devices or mechanical
contact switching devices such as relay contacts, push buttons (in normal or harsh
environmental conditions), and two- or three-wire proximity switches.
IEEE Institute of Electrical and Electronics Engineers, Inc. The international standards
and conformity assessment body for all fields of electrotechnology, including
electricity and electronics.
industrial I/O An Advantys STB I/O module designed at a moderate cost for typical continuous,
high-duty-cycle applications. Modules of this type often feature standard IEC
threshold ratings, usually providing user-configurable parameter options, on-board
protection, good resolution, and field wiring options. They are designed to operate
in moderate-to-high temperature ranges.
input filtering The amount of time that a sensor must hold its signal on or off before the input
module detects the change of state.
input polarity An input channel’s polarity determines when the input module sends a 1 and when
it sends a 0 to the master controller. If the polarity is normal, an input channel will
send a 1 to the controller when its field sensor turns on. If the polarity is reverse, an
input channel will send a 0 to the controller when its field sensor turns on.
input response
time
The time it takes for an input channel to receive a signal from the field sensor and
put it on the island bus.
INTERBUS
protocol
The INTERBUS fieldbus protocol observes a master/slave network model with an
active ring topology, having all devices integrated in a closed transmission path.
IP internet protocol. That part of the TCP/IP protocol family that tracks the internet
addresses of nodes, routes outgoing messages, and recognizes incoming
messages.
