With the Accon-EasyLog data logger, Deltalogic offers software with intuitive user guidance that enables data to be read out and saved from the PLC. Accon-EasyLog communicates with the currently available Siemens controllers and also with Sigmatek automation systems. The software is released for the Windows XP, 7, 8.1, Server 2008 R2 and Server 2012 R2 operating systems. As the data logger is also operational without user action, users can run it as a service in the background. This makes it possible to install the software in the server room. The data logger is designed in such a way that universal data sources and different configurations can be operated simultaneously with one program. Data logging is either time or process-controlled and can be linked to various conditions. Other functions: wizard-guided parameterization, the option to output not only I/O values, but also text, as well as the use of 'virtual variables', which are calculated from the values of the controller.
