- Creation : 1989
- Know-how: software development in the field of industrial process
automation
- SCADA systems under DOS since 1983
- 1st French editor of a SCADA software for Windows (1st application
running under Windows in 1991)
- Now leader in the fields of water sector and remote supervisory
(building automation, networks,…)

- Replaces an electrical control panel
- Display (lights, Vu-meters, graph trends)
- Command (buttons)
- Faults announcement (buzzer)
|

|
- Local field networks
- Quasi real time transfer of information
- (transfer delay < 1 second)
- Time stamping of events by the computer: time accuracy of 1 second is
coherent with human reaction delay.
- Local diffusion of process information: factory model
|
|

|
- Factory model: information available locally (LAN)

- Custom spreadsheet:
- No programming language
- Speed (precompiled formulas, no slow down as with scripts)
- Database processing level (<>mimics)
- Powerful events/alarms manager
- Efficient graph trend tools
- True network Client/Server architecture: application server
|
|

|
- Data Client/Server:
- Application 2 asks for data of application 1
- Addresses are different in applications 1 & 2
|
|
10
|
- Application Client/Server:
- Client “opens” Application 1
- Client station behaves exactly as master station
|
|
11
|
- Distributed items
- Mimic displays (viewing & commands) with incorporated graph trends
- Worksheets
- Logs/Events views
- Elementary data
|

- TOPKAPI Vision has originally
been designed as an application Client/Server system for remote
communications, that is why it brings:
- Communication efficiency
- Data transfer optimization
- Automatic update of remote client configuration
- … but also the benefits of a built-in system:
- Redundancy
- Automatic switching
- Full data storage recovery
- Easy configuration
- Shared processing
- Unique application
- Performance
- Reliability

- Automatic download of time-stamped data (differential: only new)
- Only the connected units are scanned (optimized polling)
- Data storage performed as if data had been acquired locally (Merge
process)
- TOPKAPI does not store the RTUs' raw value, but the value as it has been
customized for the display: data configuration is UNIQUE for real time
and time-stamped.
- Alarms and events displays with time of the event (stored by the RTU),
and computer reception time (i.e. the time the operator has been
advised)
