Whether in production or logistics, communication modules allow you to connect our SIMATIC Ident systems (radio frequency identification [RFID] and optical identification systems) to SIMATIC controllers, PC-based systems, or controllers from third-party suppliers. The new RF18xC communication modules even support RFID-based digitalization solutions in industrial automation, thus paving the way for connecting HF RFID systems to the cloud. As part of TIA, the communication modules can be efficiently integrated in the SIMATIC world.

Integration in TIA Portal enables simple parameterization and provides for fail-safe planning. Standard function blocks, also integrated in TIA Portal, ensure that existing Ident applications are operational immediately, even if you change readers.

Communication modules at a glance

Versions with different interfaces are available for optimally integrating the SIMATIC Ident systems in Totally Integrated Automation (TIA). The communication modules are ideal for use in all areas of automation. Their particularly compact design and high degree of protection enables the devices to be used in harsh industrial environments and wherever space is restricted.
