Following the successful introduction of the Simatic RF185C, RF186C and RF188C communication modules, Siemens is launching two additional devices on the market: Simatic RF186CI and RF188CI. As well as the option to connect two or four Radio Frequency Identification(RFID) readers, both modules have an additional port for digital I/Os (Input/Output). The basis for this is an integrated IO-Link Master. For the new modules, access to configuration, commissioning and diagnostics tools is no longer simply supported via the proven TIA (Totally Integrated Automation) Portal but now also via web-based management. Simatic RF185C, RF186C/CI and RF188C/CI support OPC UA (Unified Architecture – standard for data exchange as a platform-independent, service-oriented architecture) as their interface to the IoT (Internet of Things) world, and communicate via the OPC UA Auto ID Companion specification V1.0 data model. This enables manufacturer-independent communication within the automation and a standardized connection to cloud applications such as MindSphere – the open, cloud-based IoT operating system – through an industrial IoT gateway. Siemens is therefore paving the way for high frequency (HF) RFID cloud connection.
