Hello, I am working with PLC S7-300 with an ethernet module CP343-1 Advanced IT, connected to PC station with WinCC RT Advanced by IE general (via ethernet). The aim is to control speed of AC motor with Frequency inverter G120 CU240S 2 DP F. I configured all the devices, done programming and my Motor runs correctly when I control it from Watch table. But I canot control it from WinCC even though I am usim exact the same tags in watch table and WinCC. There is no errors, nothing, it just doesn't work. What could be an issue? I had a problem, when i start wincc pop-up appears and says: Licence for Sm@rtServer missing, and too many Tags (Powertags) configured. When I activated that licence, the pop-up didn't show up any more. I am using Standard Telegram 1 for communication with G120. I am sending two words: control word and setpoint, and receiving 2 words: status word and actual speed value. The tags with its addresses are shown here: http://pokit.org/get/?85ff0dad960bd743601b55f416eae597.jpg HMI tags are shown here: http://pokit.org/get/?295ae7ccf4a8da15ddd3e5db4dde59b2.jpg Access mode is <absolute access> and Acquisition cycle is 100ms here. I don't know what's wrong since there are no errors, control works when I send commands from watch table, but not from wincc.
