OPC is actually a common standard in industry.
Industry 4.0 requires OPC UA.

With the Tani OPC Toolkit your applications gets access to all computers, industrial controllers and devices which are offering OPC. Various manufacturers are offering OPC servers for accessing special devices. So you get access to your complete plant.

The Tani OPC Toolkit supports various operating systems and hardware platforms.

The functions provided by the OPC Toolkits are used unchanged in the Tani products.
Under Windows there are OPC DA, OPC UA and OpcPipe client functions. Of course Linux does not know OPC DA, because it is based on Mircosoft DCOM.
Due to the wide distribution of the products there is interoperability to all systems on the market. Because Tani uses the toolkits itself intensively, the underlying libraries are also maintained. For this reason alone, the programming API must always remain stable. This is the case in all toolkits. Even after many years, you will always have up-to-date software without having to adapt the program code.
Service packs for current libraries can be downloaded free of charge from tanindustrie.de.
