Three display sections
The display is divided into three sections.
Top section of display
The top section of the display provides information about the Universal Control Network (UCN).
The UCN status at the top of the display is defined in the following table.
Table 23 UCN Status Display
– UCN/NIM Status
Term Definition
UCN CABLE STATUS Indicates status of the UCN cables. (OK or FAIL)
UCN CONTROL STATE There are two control states. The BASIC state does
not permit LCN devices to write to any devices on the
UCN. The FULL state permits LCN devices to write
to the UCN devices.
UCN AUTO CHECKPNT
There are two automatic UCN Checkpoint states.
The ENABLE state permits automatic Checkpointing.
The database is saved in the History Module
periodically for the devices that are individually
Checkpoint enabled. The INHIBIT state prevents all
devices on the UCN from Checkpointing.
NIM AUTO CHECKPNT There are two automatic NIM Checkpoint states. The
ENABLE state permits automatic Checkpointing. The
database is saved in the History Module periodically
for the devices that are individually Checkpoint
enabled. The DISABLE state prevents all devices on
the UCN from Checkpointing.
Middle section of display
The “status boxes” in the middle grid-like section of the display provide the status of the configured
UCN node.
Type of device
The type of device on the UCN is identified at the upper center of the status box, such as HPM, APM,
PM, LM, or NIM.
Primary or secondary
When redundant, the numerals in the left and right upper corners identify the primary and secondary (if
present) node addresses of the device, respectively.
Device status
Two lines in the center of the status box indicate the device’s primary and secondary (if present) status.
For the HPM, the first line is the composite status of the primary HPMM, and the second line is the
status of the secondary HPMM. The composite primary HPMM status reflects the status of the HPMM
and all the IOPs.
