Specifications

G-v
Intrinsic Safety barrier
A physical entity that limits the current and voltage into a hazardous area in
order to satisfy Intrinsic Safety requirements.
IrDA
Infrared Data Association, a non-profit trade association that establishes
standards for infrared communications between devices such as personal
computers, printers, and handheld devices.
Link Active Scheduler (LAS)
The bus arbiter for the segment. The LAS recognizes and adds new devices
to the link, removes non-responsive devices from the link, and distributes
Data Link (DL) and Link Scheduling (LS) time on the link.
Link Master
A Link Master device controls when devices access the fieldbus and
executes the link schedule, which synchronizes communications with
function block execution on the fieldbus. The H1 card or any field device that
supports Link Master functionality can function as a Link Master device. Only
one Link Master device can be active at a time on the fieldbus segment. This
device is called the LAS.
Link Scheduling time
Link Scheduling time is a link-specific time represented as an offset from
Data Link Time. It is used to indicate when the LAS on each link begins and
repeats its schedule. System management uses it to synchronize function
block execution with the data transfers scheduled by the LAS.
Lithium Ion Power Module
A Lithium Ion (Li-Ion) battery used to power the 375 Field Communicator. The
Power Module has a green, 6-pin power supply/charger connector. See
Figure 2-3 on page 2-11 for the location of this connector. The Power Module
must be charged by the power supply/charger with the green connector.
NiMH Adapter Cable
A cable used to recharge a NiMH Battery Pack with the power
supply/charger. The colors on the adapter cable connectors match the
corresponding connectors on the NiMH Battery Pack and the power
supply/charger.
