3. UCN Status Displays
3.1 Overview
Introduction
The information in this section is intended to assist the reader in the operation and understanding of UCN
Status displays as a service tool for the High-Performance Process Manager equipment. The UCN Status
displays consist of three categories of displays, the NIM Detail Status displays, the HPMM Detail Status
displays, and the IOP Detail Status displays for the following types of Input/Output Processors (IOPs).

High Level Analog Input (HLAI)

Low Level Analog Input (LLAI)

Analog Output (AO)

Digital Input (DI)

Digital Output (DO)

Smart Transmitter Interface (STI)

Smart Transmitter Interface Multivariable (STIM)

Low Level Multiplexer (LLMux)

Remote Hardened Low Level Multiplexer (RHMUX)

Pulse Input (PI)

Serial Device Interface (SDI)

Serial Interface (SI)

Digital Input Sequence Of Events (DISOE)
References
Numerous references in this section are made to figures that represent screen prints of the actual
Universal Station Console displays. It should be possible for the reader to make use of either the figures
in this section, or the screen display on an available Universal Station hosting the Operator or Universal
personality as a training or service tool.

3.2 Display Definitions
IOM definition
A common word in the display discussion is the term “IOM.” The Input /Output Module (IOM) is the
Input/Output Processor (IOP) card that resides in an High-Performance Process Manager card file. It
interfaces to an associated Field Termination Assembly (FTA). In the case of redundancy, the IOM
consists of two IOPs with the associated FTA.
Target selection
Often, a figure has the title of a display followed by the name of a target on a display, such as: IOM IOL
INFO
. This is the target that must be selected on a previous display to produce the display in the figure.
NIM Detail Status Displays
These displays provide the operator with access to the current status of a primary or secondary NIM as a
UCN node. The display contains a fixed portion showing the current state of the NIM on the UCN and a
set of targets that invoke displays of the UCN Driver configuration and the NIM local UCN statistics.
The NIM Local UCN Statistics display has a target that allows the operator to reset the UCN Driver
statistics for test purposes.
