Brief description

OPC (OLE for Process Control) is a standardized interface for accessing process data. It is
based on the Microsoft® standard COM/DCOM and was developed for the data access re-
quirements in automation technology. In this area it is used predominantly for reading and re-
cording control values.
OPC clients may be visualization tools and programs for operating data logging. OPC servers
are typically provided for PLC systems and fieldbus cards.
The CODESYS OPC server is a program part of the CODESYS PLC programming system.
The CODESYS OPC server
• is within the scope of delivery of the CODESYS development environment and is free,
• consists of the server and an OPC configurator,
• requires a symbol configuration in CODESYS and offers all variables which are available in
the symbol configuration.
The PLC programming system can be downloaded from the JUMO website www.jumo.de at
