  1. Good Morning All, I'm having a little difficulty with magnetic pickups. I have a V700 With the expansion adapter and two modules - the IO AI8 and a DI8 R04. I have an external 2-wire magnetic pickup that generates a sine wave Frequency with an amplitude of 1V+/- Based on the flow through a pipe with a turbine in it. In the wiring diagram, each counter/frequency shows a minimum of three wires at the pickup. Looking for guidance for how to wire this module in with the two wire pickup as described above... Any help is appreciated
  2. Hello together, i try to measure the Speed of Rotation (between 1000 1/min and 8000 1/min) with a Samba SM43-J-TA22 and an capacitiv sensor with one srew on the Motor shaft. When i use the High Speed Input in the Hardware Configuration (Frequency Measurment 1000msec) i have an very bad Resolution (Value 16 * 60 = 960 and next Value 17 *60 =1020). I've tried to use the "Freq<- HSC" building block, but it doens't work with my values. For example im not sure what i have to chose for the Channel A, because I can chose HSC 0, HSC1 and HSC2 there but I only have two HS channels on my Samba Controller. Is this the right way to measure the Speed of Roation more exactly? If yes can you give me an example how i have to config the block, and if i have to set up the High Speed Input in the Hardware Config? Thank you very much. Kind regards Stefan
  3. 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.
  4. 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
