DESIGO INSIGHT OPEN
SCADA technology
INSIGHT OPEN is a modern integration platform for direct connection to the
management level which uses vendor-neutral visualization systems based on
SCADA technology. SCADA (Supervisory Control and Data Acquisition) systems
are software products from the field of industrial automation, and can be used to
connect various automation systems using a variety of device drivers.
SCADA technology is ideal for connecting stand-alone third-party systems or open
automation and field buses, where the emphasis is on operation and monitoring
and reliable cross-disciplinary interconnection is not required. Vertical connections
are implemented with communication cards or system-specific interfaces plugged
directly into a management system PC. INSIGHT OPEN makes use of the
technological potential of Citect, a leading SCADA system supplied by
CiTechnologies Pty. Ltd., Australia.
INSIGHT OPEN is an adjunct to the DESIGO INSIGHT management station and
provides the following functions for the integrated third-party system or device:
Functions in INSIGHT OPEN
• Graphical operation of the plant and the
process.
• Alarm display and operation.
• Dynamic trend curves and long-term data
storage.
• Topological data point operation in Object
Viewer.
• Log book and message archiving.
• Alarm routing to message receivers.
• Access protection.
INSIGHT OPEN runs on Windows XP or Windows Vista on networks.
INSIGHT OPEN provides an OPC client (OLE for process control) for the
connection of third-party systems. This supports the specifications of Data Access
Version 1.0a and Version 2.0.
As a consequence, INSIGHT OPEN is an integral component of the process
control system and subject to the same high expectations in respect of reliability
and minimum downtime.
The process values transferred from third-party systems to the DESIGO INSIGHT
management station are mapped as SCADA process variables, or "variable tags".
Special tags are used for alarm and trend variables:
• Alarm tag, alarm process variable.
• Trend tag, trend process variable.
Unlike the data points in the building automation and control system, the process
variables (tags) each contain one item of information only. Alarms and trend logs
are SCADA objects which are generated by and calculated in the I/O server.
Vendor-neutral protocols
• BACnet.
• LONWORKS.
• KNX S-mode (EIB).
Vendor-specific protocols, e.g.
• SIPORT NT (access control).
• AlgoRex (fire detection system).
