This program uses a universal Siemens driver to communicate to a wide variety of Siemens Automation Devices, including S7-300, S7-400, S7-1200, and S7-1500 processors. By configuring PLCs and Tags, you can monitor areas of memory including Data Blocks, Input/Output points, Counters, Timers, and Internal Markers (flags). You can also write to supported memory to alter your automation system's operation.
