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 sends
a 1 to the controller when its field sensor turns on. If the polarity is reverse, an input
channel sends 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.
IOC object
Island operation control object. A special object that appears in the CANopen object
dictionary when the remote virtual placeholder option is enabled in a CANopen NIM.
It is a 16-bit word that provides the fieldbus master with a mechanism for issuing
reconfiguration and start requests.
IOS object
Island operation status object. A special object that appears in the CANopen object
dictionary when the remote virtual placeholder option is enabled in a CANopen NIM.
It is a 16-bit word that reports the success of reconfiguration and start requests or
records diagnostic information in the event that a request is not completed.
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.
