"PLCcom for S7" currently does not offer symbolic access to S7 controllers.
The reasons for this lie in legal concerns as well as in different protocol implementations within the TIA firmware versions.
The only way to access symbolic tags currently approved and supported by Siemens is through the OPC UA protocol.
You are welcome to use our "Opc Ua Client Sdk" for this. The library was of course extensively tested for accessing S7 controllers.

In our company the number of employees who work on a project keeps changing. Therefore, the number of licenses required changes. Is there a possibility for a flat-rate licensing?Indian12022-09-08T10:14:40+02:00
The license model of PLCcom is kept as simple as possible.
All licenses are made available as developer licenses.
The fee-based professional license entitles a developer for industrial/commercial development of individual software (definition see EULA) with the PLCcom component.

The network participants must be able to connect with the network. The connection must not be interrupted by a firewall or similar. In particular, the port 102 in the direction of the PLC must be open.
Where can I find programming examples and the documentation?Indian12022-09-08T10:15:01+02:00
The libraries are, depending on the version, to 100% Java or .NET code.
You can embed the driver directly as a link; API calls are not necessary.
It is no problem to use the component in 32- or 64-Bit-environments, as well as across platforms.
Does PLCcom also runs in 32-Bit- and 64-Bit-environments?Indian12022-09-08T10:15:01+02:00
Due to the lack of serial ports, it is not possible to use the following objects on Android: PLCCom.MPI_Device
Attempting to create an instance of the above classes ends with an error of type java.lang.NoClassDefFoundError
Furthermore, the usage of the PLCCom.FileSystemConnector object must be at least Android API Version 26 or higher, in deviation to the above mentioned information.
Due to the general system conditions under Android, it is assumed that the use of the above-mentioned objects on Android does not matter and the restrictions are negligible.
Which system components are required for the operation of PLCcom?Indian12022-09-08T10:15:01+02:00
The .Net version supports classic .Net Framework-programming.
