  1. Frequency measurement

    Hello world, I have UniStream TP-070 with High Speed module UID-0808THS. I need to have measurement of speed of electric generator based on pulses from inductive sensor attached to the machine shaft. The frequency is typically 100 Hz for 50 Hz grid. I did not find the convenient way how to measure frequency with precision at least 0.1 Hz with update rate better than 1 sec. In VisiLogic, there is a block HSC->Frequency for High speed inputs (reload). I did not find similar way in UniLogic. Can someone help me? Thanks, Michal.
  2. Hi support and forum members I have successfully used the Visilogic project examples to log data using an SD Card. However, the example program uses SB13 to write data to the SD card every 1 second. This is far too frequent for my application. I want to log data every minute, or every 10 minutes. How can I reduce the write frequency? Do I need to use some delay timers? Can anybody assist me with the correct/optimal ladder for this. Picture of code attached. I'd also like to know how to display the free space in MB or GB left on the SD card Best Regards
