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.

Plant screen level

The plant screen level has only one screen. This screen should display in minimum the navigation to the departmental processes. It has to open after a HMI system start. This screen can display additional a general overview about the running processes of the plant.

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.

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.

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

4. RULES, HINTS AND TIPS FOR HMI SCREEN DESIGNING

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

1X1:H1


25 / 30

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.

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.
