Group display

The group display is a combination of several face

plates and contains detailed information about

associated process points. All functions, including

controllers, time and monitoring functions as well as

open-loop control functions, can be displayed and

operated.

To provide a quick source of information, analog

values are displayed as colored bars. To allow more

precise reading, they are shown as alphanumeric

values. Pending disturbance states in the respective

variables can be detected immediately through a

change in color and flashing, and can be acknowl

edged directly in the faceplate or message list.

Configured limits can be additionally displayed as

symbols. You can create your own faceplates for

user-defined function blocks.

overview display

The process information for the entire plant is pre

sented in a condensed manner in a single overview

display. It offers facilities for selecting the group,

graphic, SFC, Web, time scheduler and trend dis

plays. Logs can also be called up directly from the

overview display. Up to 96 displays (16 lines, each

with 6 displays per line) can be shown in the over

view display. The group display symbols within the

overview display also feature dynamic updating of

process points, allowing disturbance states to be

detected rapidly through appropriate symbols and

colors. If required, you can also set a graphic display

of your choice as overview display. It then replaces

the standardized overview display.

Faceplates

Faceplates allow both overview and detailed informa

tion to be obtained simultaneously. Since faceplates

are predefined, they are available immediately in the

system following the definition of a process point,

without any additional programming.

This is also the case for user-defined faceplates.

Therefore, faceplates can be displayed on a monitor

together with standardized and freely constructed

displays. A selected process point can always be

displayed via its faceplate.

Pre-engineered displays

Pre-engineered displays are adapted to the needs of

process control engineering with regard to structure

and information content. The following displays are

available:

• Overview display

• Group display

• Faceplate

• SFC display

• Time scheduler display

• Trend display

• Web display

• Message list and operator hint list

• Logs

• System display

Therefore, most functions already have fully prepared

displays for operation and observation, and can be

used without any further programming.

Plant-specific displays

Plant-specific displays geared to the specific

demands of the plant operator can be configured

to depict process activities.

Static sections of the graphic displays can be cre

ated using the graphics editor. In addition, you also

have the option of inserting such static sections in

the form of bitmaps. Current process data or process

states can be animated dynamically in a suitable

position using features such as bar graphs, dynamic

filling and trend windows.

Depending on process states, graphic symbols can

be replaced, flash, and change color and position in

the graphic display. Process points can be viewed

either via faceplates in the graphic displays or via the

standard group displays.

Display selector fields or buttons can be used to

set up a specific selection hierarchy within custom

graphics for operation. The number of custom

graphics available in DigiVis is limited only by the

hard disk capacity.

The operator level with DigiVis

The operator stations

The operator stations of the Freelance 800F system

run on common personal computers, or, in special

cases industrial PCs.

The DigiVis software package, based on Microsoft

Windows as a graphical user interface, enhances the

ease of use and the performance of process opera

tion. In addition, you can also use any PC peripherals

such as monitors, printers, mice and keyboards that

are available on the market for Windows-compliant

PCs. The operation and observation (DigiVis) and

configuration (Control Builder F) functions can also be

performed together on one PC. DigiVis operation and

observation software has the following features:

• Transparent and rapid operation due to a clearly

structured information hierarchy

• User-specific function key assignment for fast

display selection

• A large number of pre-engineered display types

• A control aspect, providing access to dynamic

interlocking displays for the selected tag (in

connection with OPC or trend server)

• An external aspect, providing access to additional

information such as PDF documentation, live

videos from the plant, standard operational pro-

cedures (SOPs), etc.

• Rapid selection of the correct measuring points in

case of process alarms

• Uniform message concept and clearly arranged

display of messages and operator hints

• Configurable voice output on the PC for messages

• Up to 16 user groups/access profiles, with a

maximum of 1000 users, specific password for

each user (with optional Security Lock software)

• Trend display with archiving

• Logging of all operator actions, including name

and timestamp

• System diagnostics, even down to the field device,

allowing full field device error diagnostics

• Various language versions: German, English,

Spanish, Swedish, Russian, Polish, French,

Chinese and Japanese

• Dual-monitor operation on a single PC, with one

mouse and one keyboard

Process visualization is supported by:

• Plant-specific custom graphic displays

• Faceplates for process points (tags)

• Up to 15 plant areas with plain text labeling

Freelance 800F provides an OPC gateway (server),

which allows OPC clients to access data and alarms

from the Freelance process stations. From Version

.1 upwards, the OPC server also allows access to

the DPV1 parameters and user parameters of

PROFIBUS and HART devices. In the case of HART

devices, this is only possible if they are connected

to a S900 unit. For V8. and higher, the parameters

of FOUNDATION Fieldbus devices can also be

accessed. It is possible to limit access to this data

at the OPC gateway such that an OPC client cannot

see certain process points and variables at all, can

only read other process points and variables, or has

both read and write access to certain

process points and variables.

The DigiVis operator station has a built-in OPC client,

which permits you to access data from external

OPC servers. Using this, for example, data from a

SIEMENS control unit can be integrated into a cus

tom graphic in DigiVis.

As several OPC gateways can be used in the Free

lance system, server redundancy can be established

using OPC clients that support this function. * The

Control Builder F engineering software supports this

with the redundant OPC gateway configuration.

The trend server option provides a special OPC

gateway that is used by the DigiVis operator stations

for user-defined trend displays. Access to the trend

server is fixed to “read only”, and all trend variables

are automatically available. There is one trend server

per Freelance system.
