EXTEND7000 Architecture
EXTEND7000 solutions are not simple Mobile applications. Behind the Mobile Client, each application utilises the EXTEND7000 server platform, which comprises a set of system components run as services and inter-communicating over http. Each service component performs a specific role in the solution supported by a set of utilities for configuration, monitoring and maintenance.
A highly scalable solution, EXTEND7000 can be deployed at a single site or, for large organisations, distributed across multiple sites when it is capable of monitoring many 100,000’s of tags and supporting many 100’s of remote users whether connected on a local Wi-Fi or Mobile Data Network.

EXTEND7000 System Manager
Defines the Projects, Users, User Groups, and escalation rules for the system. EXTEND7000's distributed architecture allows multiple Projects (Sites) on different servers to be serviced by the same users.
EXTEND7000 Service Manager
An administration tool for managing services that are running on distributed EXTEND7000 Server platforms. EXTEND7000 is a high reliability solution and includes features to automatically restart services in the unlikely event of a system error.
EXTEND7000 Project Manager
The Project Manager serves a dual purpose dependent on authorisations assigned to the user:
- A tool for administrating and maintaining the Project Database, which contains the Hardware organisation, Tag and Notification details, hierarchy, links and notification User Groups.
- Provides supervisory access to Open and Archived notifications lists. Includes filtering and ordering capabilities for monitoring progress and reviewing failure history. By browsing Plant hierarchy, the supervisor also has access to monitoring and controlling features available to Mobile users.
EXTEND7000 Maintenance Server
Provides the interface between the host Plant Maintenance System and the Mobile Client for Maintenance. Mobile users can process Work Orders, create Work Orders or view Asset history. Maintenance transactions are performed in real-time ensuring the host system is kept up-to-date and spare parts stock is always accurate.
EXTEND7000 Device Server
The Device Server manages the connection to the Mobile devices.
EXTEND7000 Mobile Client
A suitable Mobile Client must be loaded to the Mobile device before it can be used with EXTEND7000.
EXTEND7000 Notification Server
Monitors the tags for notification conditions and sends notification and escalation messages to the Mobile terminal users. Responsible for managing resolution workflow which provides the Mobile user with functionality to Accept, Revoke, Resolve or Delegate alert notifications.
EXTEND7000 Trend Server
Responsible for periodically recording data values for parameters that have trending specified in the Project. Trend recording may be triggered by a notification.
EXTEND7000 Migrator
A utility to assist in the creation of the EXTEND7000 Project Database. An EXTEND7000 solution may deploy 100,000’s of tags and it is impractical to create the EXTEND7000 Database manually. The Migrator imports data extracts from multiple sources, typically SCADA or PLC systems, and merges this data into a single database.
EXTEND7000 Communications Server
The communications server provides the gateway to the project data sources.
Operating Platforms
EXTEND7000 is designed to run on a standard Microsoft Windows platform and requires a Microsoft SQL Server database.
Operating System
- MS Windows Server 2003 Standard 32Bit
- MS Windows Server 2003 R2 Standard 32Bit
- MS Windows Server 2008 Standard 32Bit
- MS Windows Server 2008 R2 Standard 32Bit
*64Bit-OS-versions als supported by using 32Bit-compatibility mode.
Database
- Microsoft SQL Server 2005 SP3+
- Microsoft SQL Server 2008 SP1+
- Microsoft SQL Server 2008 R2
*the instance used for EXTEND 7000 must support mixed mode authentication and TCP/IP server protocol must be activated. The “free of charge” Express versions are supported up to a maximum of 5.000 parameters and a maximum of five users.
VM Operation
EXTEND 7000 can be run in a virtualized environment. Multi-processor assignment can be deployed to enhance system performance. Recommended virtualization systems are VMware ESX or ESXi, Citrix Essential or Microsoft Virtual Server.
