Wizcon for Windows and Internet
Scalable networking delivers speed and reliability
Wizcon allows a smooth migration path from a stand-alone workstation to plant-wide network architecture that connects the plant floor with existing file servers and other management systems. Wizcon's scalability allows the user to start small and grow while protecting investments in process automation and information technology. Wizcon's networking automatically detects remote Wizcon stations across any TCP/IP or NetBIOS networks.
Based on the distributed database concept, all Wizcon stations act as
data servers and clients for other stations, preserving the integrity
of tag and alarm definitions. Authorized users can access all the tags
and alarms from their remote station. For example, an alarm can be generated
in one station and acknowledged by a remote station without extra work.
Expanding a Wizcon network becomes a matter of simply adding stations.
Distributed database preserves data integrity
Wizcon’s network can be constructed from different types of network nodes
according to the specific needs of each application. Wizcon’s network
is based on client-server architecture, allowing stations to transfer
and receive real-time and historical data. The client-server design allows
users to transparently define network data objects, without defining network
tags or alarms in the local configuration database. The tags users define
in one station are instantly available for use in any other station across
the network. This configuration cuts the number of licenses required and
preserves database integrity.
Wizcon SCADA stations
Each Wizcon SCADA station can communicate with up to 32 networks of field
devices simultaneously. This station performs all standard SCADA functions,
such as sampling PLCs, generating alarms, collecting historical data and
performing control operations. The operator can view the process through
the Wizcon user-interface and interact with on-going activities. The Wizcon
SCADA station can receive and send data from and to other network stations.
Integrated hot-backup configuration
To ensure the highest level of system availability, Wizcon includes Hot-Backup
capability as standard. The Hot-Backup mode consists of two identical
Wizcon SCADA stations connected to the same I/O. One SCADA station is
running in master mode and samples data while the other remains in standby.
If the master fails, the backup station automatically takes over all functions,
including communication over the network. Once the master recovers, the
backup station stops sampling data and updates the historical database
on the master station. This mechanism ensures that the historical database
on the master station remains complete.
In normal operation, both the master and backup stations can be used as independent operator stations. The only requirement is that the application running in the master and backup stations should be identical.
Remote network update
Wizcon Supervisor allows application developers to remotely update several Wizcon stations on a network from a main station. A user-friendly interface guides the operator in selecting the files and directories, station by station, and in saving the setting for later update.
