Softing presents version 4.45 of the Datafeed OPC Suite. In addition to a REST Connector and support for NoSQL databases, direct symbolic data access to 'optimized blocks' in Siemens Simatic S7-1200 and -1500 controllers is now also possible. The REST Connector enables the integration of data from a variety of devices in automation networks into applications that support REST protocols. Data sources can be controllers from manufacturers such as Siemens, Rockwell, Mitsubishi and B&R, for example, or OPC UA or OPC Classic servers. Together with support for write access to NoSQL databases such as MongoDB, the software is equipped for IoT and Industry 4.0 applications. REST protocols are used in particular for communication with cloud-based applications, such as the 'Production Performance Manager' from Bosch Software Innovations. NoSQL databases enable the high-performance processing of very large amounts of data and are therefore often the basis for advanced analysis processes that can be used for predictive maintenance, for example. In addition to the integrated REST interface, the MQTT gateway and support for OPC UA enable the integration of older and new control systems in cloud solutions such as Microsoft Azure or IBM Bluemix.
