Mixed architectures
In this type of architecture FactoryCast HMI supplements conventional SCADA
systems, such as Vijeo Look or Monitor Pro, which meet the requirement for
centralizing information for global supervision from a central site.
Combining a FactoryCast HMI solution and a conventional SCADA solution enables:
b
Simplification of the SCADA application by locating some of the SCADA
processing functions at source, at PLC level
b
Increased availability of the traceability function due to the direct connection
between FactoryCast HMI modules and relational databases
b
Powerful ready to use remote diagnostics capability
b
“
Nomad” client stations to be connected to the Intranet or Internet via Thin Client
PC or PDA devices
Direct links with information management levels
In this type of architecture, FactoryCast HMI eliminates the need for intermediate
devices (software or hardware gateways), which are expensive to install and
maintain, by establishing direct links between the automation levels and the global
information management levels (MES, ERP, etc.).
The PLC manages the following links which allow a “collaborative” automation
system to be set up, making it easier to share data in real time:
b
Direct archiving of information from the automation system in relational databases
b
Direct interaction with IT applications via the SOAP/XML client/server interface
This solution results in:
b
Simplified architectures
b
Lower installation, development and maintenance costs
b
Increased reliability of information (the data is collected at source)
b
Increased interoperability with IT applications
b
Greater availability of data archiving
