    Abstract: A programmable logic controller (PLC) protocol converter is disclosed that allows a supervisory control and data acquisition (SCADA) system to effectively communicate with a PLC device using a desired communications protocol, particularly in cases where the PLC device does not “speak” the desired communications protocol. A first thread may be configured to continually read PLC addresses, one at a time, using a communications protocol understood by the PLC device. The first thread may store the data values in the shared data array within program memory. Thus, the first thread exposes data from the PLC device, as specified in the configuration file. At the same time, a second thread may be configured to serve the data in the shared data array according to a second communications protocol, e.g., to the SCADA system.

    Abstract translation: 公开了一种可编程逻辑控制器（PLC）协议转换器，其允许监控和数据采集（SCADA）系统使用期望的通信协议有效地与PLC设备通信，特别是在PLC设备不“说”所需的通信协议的情况下 通讯协议 第一线程可以被配置为使用PLC设备理解的通信协议来一次一个地连续地读取PLC地址。 第一个线程可以将数据值存储在程序存储器中的共享数据阵列中。 因此，第一个线程从配置文件中指定了PLC设备的数据。 同时，第二线程可以被配置为根据第二通信协议（例如，到SCADA系统）来服务共享数据阵列中的数据。

    Abstract: The invention relates to a method and a bus system for the interchange of device-specific data between fieldbus slaves of a first fieldbus and a fieldbus master of a second fieldbus, wherein the first fieldbus is connected for communication to a common Ethernet network via a first gateway and the second fieldbus is connected for communication to a common Ethernet network via a second gateway, wherein the communication via the Ethernet network occurs according to the client-server communication principle, wherein the first gateway reacts on the network side as a fieldbus master and on the Ethernet side as a web service server, and wherein the second gateway reacts on the fieldbus side as a fieldbus slave and on the Ethernet side as a web service client.

    Abstract: A network unit in a programmable controller of a building block mutually connects an information system network and a control system network. The network unit includes transfer analyzing units that judge to which of interface units received data received from the information system network and the control system network should be allocated. Moreover, received data that needs to be transferred is converted into predetermined data by conversion processing units included in the networks and output to the information system network or the control system network without being transmitted to a system bus.
