PLCopen and OPC Foundation combine technologies About
a year ago PLCopen and the OPC Foundation joined forces to combine their
technologies to a platform and manufacturer-independent information and
communication architecture. A combined working group was started, focused to the
mix of OPC Unified Architecture (UA) and IEC 61131-3, which creates interesting
options for the realization of automation structures. Today
there are many historically grown data exchange protocols used in various
industries. They offer little possibility to transport complex data and the
extensibility is very limited. OPC Unified Architecture however, offers the
basis for universal, secure and reliable network communication, i.e. provides
the monitoring of configurable timeouts and connecting interruptions and
encrypted communication. To use this communication as a standard for the IEC
61131 environment will lead in many industries to a completely new form of
information exchange: If an industry has defined a specific profile e.g. a data
structure or a function block, then the question of secured and efficient data
exchange and the reusability of the visualization objects is already solved.
With the combination of PLCopen and OPC UA, an additional level of
interoperability is standardized on top of IEC61131-3. You
can read more on the cooperation between PLCopen and
OPC Foundation on our website www.plcopen.org/pages/tc4_communication/. <<back
