Institute of Electrical and Electronic Engineers
Ingress Protection acc. to IEC 60529
Ingress Protection classes (IP classes) define, on the one hand, the measures for
protection against hazardous voltages (touch protection) and, on the other,
protection measures against moisture.
Inquiry
®
An "Inquiry" (request/information), in Bluetooth technology, is a process in
®
which Bluetooth devices within range are sought.
Internal data bus
With WAGO, an internal data bus is the internal bus of the WAGO-I/O-SYSTEM
750/753.
ISM
(Industrial, Scientific, and Medical Band)
ISM bands are frequency bands that can be used license-free with the observation
®
of certain criteria. In addition to Bluetooth other wide-spread wireless
technologies such as WLAN use the ISM band at 2.45 GHz according to IEEE
802.11.
L
Latency
The latency of the data transmission indicates how long after transmission a data
packet to a local interface that same data packet is available to a remote interface.
LED
(Light-Emitting Diode)
Library
Collection of modules available to the programmer in the WAGO-I/O-PRO CAA
programming tool for creating control programs in accordance with IEC 61131-3.
Link Key
Connection key issued using device information and (optionally) a PIN, which
allows a secure Authentication of other devices.
Local I/O module
For this I/O module: A 750-644 I/O module that can be reached through a local
interface (for example, linked by wire through a fieldbus).
Example: Configuration via WAGO-I/O-CHECK.
