  1. Hello everyone I have a challenge that I cannot solve a P1 telegram (ASCII string) is sent from an electricity meter every 7 seconds How can I process this in Unistream And where should I buffer it, this because of over 700 ASCII characters in the telegram must search for the value after a code The telegram is not fixed in length, and line number 42/5000 Below a scan of PuTTY /ISk5\2MT382-1000 1-3:0.2.8(50)
  2. Hello to all , I'm struggling with reading out a smart power meter I want to use the (float) values of a telegram in a building automation project The data I get through an RS232 card UAC-01RS2 Which are directly linked to the P1 of the Smart Power Meter This is automatically sent every 10 seconds by the Smart Power Meter I read the telegram in the buffer by using the COM Rx function But how do I filter the (float) values out of the telegram Start = / End =! After the! = CRC16 using the polynomial: x16 + x15 + x2 + 1 The telegram scan by PuTTY -------------------------------
