Whichever RFID system or code reading system you connect to SIMATIC PLCs, PCs or PLCs from other manufacturers: the communication module provides for the necessary adaptation. In doing so, communication modules can be employed both for production and logistics applications. With the function block FC/FB 45, the readers of all RFID systems as well as code reading systems SIMATIC MV420/ MV440 can be handled standardized. This ensures that existing applications are operational immediately and do not have to be rewritten when another reader type is used.
