Supports PLCcom querying or writing variables with symbolic addressing from a S7 PLC?2022-02-14T15:57:43+01:00

"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.

Important notes for using PLCcom on Android2021-09-06T10:55:48+02:00

Due to the lack of serial ports, it is not possible to use the following objects on Android:
PLCCom.MPI_Device

PLCCom.PPI_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.
