ICE-128/112051/ml s 8 g4.0 ORGANIZATIOH OF DATA gSPOS data is organized into a hierarchy of pages compatible with the f
Critical Function Monitoring System (CFMS).
Figure 4.1 shows the page hierarchy.
The page. layouts are shown in the Appendices.
4.1 The
()SPDS parameters are organized into three top level systems:
- Core, Reactor Coolant System (RCS),
and Containment (CHNT).
Three pages at the top of the hierarchy (level one) are dedicated to these systems.
These pages display the minimum set of SPDS parameters as a
backup to the CFi6 for seismic conditions.
The top level ICC parameters are displayed under the Core Heat Removal function on the Core page.
At level two, there are three sector pages which provide increased detail for the ICC variables on the Core page:
Saturation Margin (SATM), Reactor Vessel Level '(RYL), and Core Exit Thermocouples (CETC).
At level three, there are two sector paqes which provide increased detail for the RYL and CETC pages:
Heated 0unction Thermocouples
(}UTC), and Core Map.
4.2 Also at level one of the page hierarchy are a directory page and a
diagnostic page.
Additional pages may be added at any level to meet plant speci fic needs.

PAGE FORMATS Display pages are designed to present information clearly and concisely.
Page loading is.l.ow.
The parameters displayed on each system page are organized into several groups wi.h a subtitle and a
surrounding frame for separation.
The ICC supporting pages are specially designed to give the best presentation.
The display pages consi st of two types of data: static and dynamic.
5.1 STATIC PAGE DATA Static page data is written on the. display when the page is initially selected and is unchanged wl en the page is updated.
Static page data includes the following:
Page
Title:
Page Humber:
Frames:
Subti tles:
Column Headings:
Parameter Hames or IDs:
Units:
Graphics:
8 x 16 letters centered near the top Three 7 x 10 digits in upper.right corner Rectangular boxes framing parameters that are l o gica 1 ly related.
7 x 10 letters describing frames or tables 7 x 10 letters labeling tables 7 x 10 letters describing parameters 7 x 10 letters and/or special characters describing measurement units Fixed portion of a graph or drawing.
5.2 DYHAMIC PAGE DATA
'II Dynamic page data may be changed when a page is updated and includes the following:
1.
Heartbeat:
8 x 8 rectanole in upper left corner is redrawn solid or clear (alternately) each time the page is updated.
Specification Ho. HPROD-ICE-3202 Revi sion 00 Page 10 of 18
ICE-128/112051/ml s 11 2.
System Alarm Indicators:
Legends for the three systems (consisting of 7 x 10 letters and page numbers) are enclosed by small frames at bottom center of each page.
The legends are rewritten each time the page is updated.
The mode indicates the alarm status of each system.
3.
Parameter Values:
7 x 10 alphanumerics representing analog or binary parameter values are rewritten each time the page is updated.
The mode indicates the alarm status of each parameter.
Table 5.2.-1 shows the formats used for parameter values.
4.
Sector Numbers:
8 x 16 num rais indicating relevant sector pages (if any) are rewritten each time the page is updated.
The mode indicates the alarm status of each sector.
5.
Graphics:
Variable portions of a graph or a drawing are redrawn each time the page is updated.
6.
System Error Message:
7 x 10 alphanuoerics indicating' current gSPDS malfunction are rewritten in the lower right corner of the display i,n.blink mode each time the page is updated.
7.
Operator Error Message:
7 x 10 alphanumerics indicating a current operator error are written in the lower left corner of the display in inverse mode each time the page is updated.

I ICE-128/1120S1'/ml s 13 6.0 ALARM BEHAVIOR The display is modified to attract and direct the attention of the operator when any of the following conditions occur:
1.
Parameter Alarm 2.
3.
System Error'perator Error These conditions are described in the following paragraphs.
6.1 PARAMETER ALARMS There are two types of parameter alarms:
setpoint and bad data.
The setpoint alarm occurs when a parameter value exceeds its high or low setpoint.
(Hote that not all parameters have setpoints.)
The bad data alarm occurs when a parameter value exceeds its all'owable range.
This may be the result of an out-of-range
- sensor, a failed sensor, an electrical failure, or a software error.
Nhen a parameter alarm occurs, the relevant+ top level system enters the alarm state and the corresponding system alarm indicator on the current display page is shown in blink mode. If the parameter is shayn on a lower level sector'page, higher level pages will show the relevant sector numbers in blink mode.
In the case of a setpoint alarm, the parameter value is shown in inverse mode with an adjacent asterisk.
In the case of a bad data alarm, the parameter value field is filled with question marks in write mode with an adjacent asterisk.
Some parameters may be shared by seve'ral systems but each parameter is considered. to he essential to only one relevant system.

na
ICE-128/ I12Q51/ml s 14 When the operator acknowledges a parameter alarm, the relevant system alarm indicator and sector numbers remain in inverse mode and a second asterisk is sh~n next to the parameter value field.
A summary of display behavior For parameter'alarms is shown in Table 6.1.
6.2 SYSTEM ERROR Mhen a system hardware or software error is detected, the message "SYSTEM ERROR" is shown in blink mode in the,lever. right hand corner of the display.
The diagnostic page gives a description of the system error.
The system error message is displayed until the error is no longer detected.
6.3 OPERATOR ERROR When an error is made at the PCM keyboard, a message is shown in write mode at the 1 mer left corner of the current display page.
The operator error messages include:
ENTE R P AGE OR SECTOR FI RST, ILLEGAL EXECUTE ILLEGAL PAGE NUMBER ILLEGAL SECTOR NUMBER NO SECTOR ZERO FROM HERE
'4 An operator error message is shown for several seconds and then erased.
