    what is the differnce between 32 bit signed and unasigned number... also the value according to your ladder diagram is signed or unasigned stored in d500

    OK.. JUST FOR knowledge.. 32bit register can store value upto 2(power32) right?

    you cleared alot .. but i want to know one thing. my values in register in case of total .. for example if we add d10 d12 d12 then d12has total values... when if we add and add .. then i want d12 has to stored more value.. will a 32 bit operation work for me or not..

    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..
