5.10 Loop I/O Carriers
5.10.1 Description
The loop units BN-303, BN-304, BN-305 and BN-306 are defined as
Loop I/O Carriers.
A Loop I/O Carrier is a loop unit hosting one or several I/O subunits.
The Loop I/O Carrier itself and all the input/outputs are assigned
separate loop unit IDs.
The Loop I/O Carrier’s dipswitch setting determines which function is
assigned to the inputs/outputs. A Loop I/O Carrier may only have
one function, which falls into one of the following categories:
Point
Inputs with function Prealarm and/or Alarm and/or Fault, all
latching,
except BN-30x/E Prealarm
Input
Inputs are either On or Off
Inputs may also give “Supervisory Alarm” (configurable)
Output
Outputs are either On or Off
Outputs may also give "Supervisory Alarm" (configurable).
Outputs configured to function K, L or M are either Steady On or Off.
These units are also using sensor inputs (used for monitoring of the
output). The sensor inputs are either On, Off, or Undetermined.
The subunits of a Loop I/O carrier are also present in the listing of
units of menu commands Points, Loop Inputs and Loop Outputs.
