1. GENERAL REMARKS
This document describes the following main items of a HMI: - The screen hierarchy - The main screen architecture - The screen navigation concept - The rules how to draw graphic screens In this document main part the ideal concept will be defined independent from the applied HMI system. The annex 1-3 will then show how these definition can be optimal applied to the Holcims standardized HMI systems from Siemens (CEMAT), Rockwell (FactoryTalk View) and ABB (ABB IndustrialIT 800xA). The document does not describe the screen content and the basic use of colors, because this is already done in the Standard Design Criteria.

Departmental hierarchy
The ideal solution is to have only one screen to display the process of one production line of this department (e.g. a cement mill process). If one screen is not sufficient to display the process, it can be split as exception in a second or third screen. For multiple production lines additional departmental hierarchies should be defined. Additional a general departmental overview over all production lines can be defined.

Description
Main departments 2 Raw material preparation (Crusher) 3 Raw meal preparation (Raw mill) 4 Clinker production (Kiln) 5 Cement grinding (Cem mill) 6 Packing and shipping (Expedition) Pre process departments
K Additives handling L Traditional fuel handling V Alternative fuel handling X Correctives handling Auxiliarie departments
M Water supply E Electrical power (Singel line diagram) D General plant services (Compressed air etc.)
Other departments (see HAC manual) should be added as needed. To display common process parts of two departments (e.g. the gas flow between kiln and raw mill or additive handling to multiple cement mills), a common screen should be created and applied to the department screen level.

2.7 Screen architecture
The HMI should be built by several basic screen layout witch have to be applied for the complete system. Such basic screens are: - Process screen (Process graphics) - Trend screen (Set of trend curves) - Message screen (Alarm and Events) - Service screen (Recipes, PCS system info, etc Every type of screens has its own screen architecture. But this architecture should be similar to all screens of same type. Every type of screen should be partitioned in several standardized areas as following: Process areas: - Graphic area -.Trend area - Message area Navigation and operation areas - Plant wide navigation area - Department wide navigation area - Common HMI system navigation area - Family wide navigation area Navigation- and operation areas should be placed on top, on bottom or at the side of the screen.

3. DISPLAYING ALARMS AND EVENTS
3.1 Message line content
As described in the Standard Design Criteria the following information has to be treated as a minimum in an alarm screen and a message screen.

08.11.2008 17:57:02 W 532-1X1.TA:H 85 Mill drive @ CM building / +0m Temp high
Type and status of the message have to be defined by codes according the definitions in the Standard Design Criteria. Additionally colors can be used to distinguish between type and / or status. But it is strongly recommended to apply colors restrictive to get an easy screen view. Example for message type code:
Message type Code examples
Failure F, Failure, !
Warning W, Warning, #

The praxis shows that every person who designs HMI graphic screens has his own understanding and creativity to draw a process for screen display. To reduce such creativity and to get group wide a more consistent philosophy the following chapter will give a guide line to create process graphic screens for the cement production. This will be done giving good and bad examples.
4.1 Rules for graphics and mimics
4.1.1 Equipment drawing and TAG naming
For designing HMI screens the colors as defined in the Holcim Standard Design Criteria have to be applied Standing process
Rules: For TAG's To every equipment has to be assigned a
field indicating its TAG name applying the HAC. If the equipment is electrically driven (motor, valve, heating etc), then clicking on this TAG should open the popup window which controls the drive of this equipment.
The TAG name can be full HAC or reduced HAC depends on the following conditions.
BC1
SG1
531-RF1
LD1 VE1
M BE1.M1
BE1.M2
Rules: Non animated equipment remains transparent or shadowed gray
Normally no motor will be drawn with the exception of multiple drives for the same machine or for big motors (see below) Standing equipment has light gray color
Condition Use of HAC TAG name The screen includes only one process group
HAC 456 BC1
The screen includes several process groups
HAC 123-456 531-RF1
An equipment (machine) has more than one drive (e.g. Bucket elevator)
HAC 456.78 or HAC 123-456.78
BE1.M1 BE1.M2 or 531-BC1.M1531-BC1.M2

Big drives
Rules: For big drives (including eventually also auxiliary drives) or drives with additional equipment the motor should be drawn as mimic 1X1.M1 HU1
1X1.M3 1X1.M2

4.1.2 Display of process status and operation status (Colors)
Rules: Process driven status information has to be indicated by color changes and visibility changes of the assigned object. Operator driven status information has to be displayed by additional mimic objects.
Display of TAG names
Rules: The back color of the equipment names has to be applied as follows: Process status
Error status
Alarm status
Back color
Standing No error No alarm -SG1 Standing error No alarm -RF1 Running No error No alarm -LD1 Running error Warninge -BC1 Running error Failure -VE1
Additionally a color filed has to be assigned to
the tag for displaying the following additional status Operation status Field color Single start mode blue Local operation mode white Automatic operation mode no visible Override (simulation) orange
BC1
SG1
RF1
LD1 VE1
Display of analog values
Rules: The display of analog values has to be an active field. Clicking on the display field has to open the popup window to treat the analog value: The back color of the value display field has to be applied as follows:
Process status (Value) Alarm
status Back color
Value in limit No alarm 87 % Value out of warning limit Warning 87 % Value out of failure limit Failure 87 % Value simulated No alarm 87 % Value simulated Warning 87 % Value simulated Failure 87 % Value under flow (<4mA) Failure 87 %
If the analog value is in override modus (simulation)
by the PCS, then it has to marked with the additional orange square mimic.
LD1 87 %
LD1 87 %
LD1 87 %
LD1 87 %

Display of digital values
Rules: Digital sensors (speed switches, drift switches, level switches etc. ) will be displayed only in case of an error as following
Process status
Sensor status
Alarm status
Back color
Standing No error No alarm Standing error x X1 Running No error No alarm Running error Warning R1 Running error Failure D1
If the digital value or an object is in override status (simulation) by the PCS, then the additional orange square mimic field has to be displayed and the digital object has to be visible in light gray.
In case when only the OK status of the digital signal can be set, the digital object itself can by displayed with an orange background.
D1
SG1 LD1
R1
X1
S1 RF1

4.1.3 Display of bar graphs
Rules: Analog values as bar graph have to be displayed as brown bar mimic. This bar graph color will not change. The analog value display has to change the color according the description above.

4.1.4 Display of selection and status information's
Single selection (e.g. On/Off)
Rules: Single selections (e.g. On/Off) have to be defined with push buttons as following: Button status Button
color Selection status
Selection is disabled (no action possible) Heating's OFF
Selection is enabled) (selection is possible) Heating's OFF
Selection is activated (Selected) Heating's ON
Heating's OFF
Heating's OFF
Heating's ON
Multiple selection (e.g. Silos))
Rules: Multiple selections (e.g. silos) have to be defined with push buttons as following: Selection status Button
color Selection is activated (Selected) -3S3
Selection is enabled) (selection is possible) -3S2
Selection is disabled (no action possible) -3S1
Prod
uct 2
Prod
uct 3
Prod
uct 1
-3S1 -3S2 -3S3
Status informations (e.g. actually production)
Rules: Information's and Status about the process should be written in white on blue back color.
(e.g. actually produced product)

4.1.5 Best practice for graphics and mimics
4.1.5.1 Don’t use
No moving objects
Rules: Do not draw continuous moving mimics
No 3 dimensional objects
Rules: Try not to draw 3 dimensional; you … … lose time, … lose place The object looks to complex
Apply only shadowing to get the 3 dimensional feeling
HMI Screen Design Guideline Reference No.: CMS-ECT 08/1442/E Revision No.: V 1.1
29 / 30
No complex object designs
Rules: Do not draw complex objects Keep the simple and understandable
Doing this, the objects can often designed smaller to save space
Do not use the color "running" for non driven equipment
Rules: Try to not apply normally green color for non driven objects (e. g silos)
Typical exception is an air slide

4.1.5.2 Use
Use Static position movements
Rules: Apply static mimics to show different position of moving objects
