  3. according to transmitter output i have taken raw value for analog .. the raw or digital value then i compare and insert all values for transmitter to register.

    i have just limitation to over flow.. when i use d500 as it is a 16bit register.. i just want to use 32 bit register.. and dont know procedure.. also help me out to find totalizer..


  4. Hello all ... i am a new plc user.. i am using D500 for taking value as it is a latched register. 

    i am taking value for a flow meter. i have two questions.

    1. how totalizer is calculated from flow rate as my flow rate is in m3/h.

    2. the value of register is gone upto 32000 approximately... i want that this value to go on.. i mean how 32 bit register is declared in plc .. a


  5. my laptop has com port 1... my cable is 9pin to plc connector .. when i connect easybuilder to hmi .. it connects and download the program.. same as when i connect plc to gx developer it connects and download the program.. also online simulation in easybuilder it shows plc data.. but when i connect hmi and plc to each other without plc.. then it shows no plc response.
