Mathematic-based instructions.

[Hairi]

Hi there!

Kinda desperate for helps right now. I been working on Mitsubishi's MELSEC FX-32MR plc with MELSEC Series GPP for Windows to develop some mathematic-based functions. The problem is I couldn't find any standard instruction to be used to carry out those functions.

Anyone could help?

TQ.

[SUB D1 D2 D3] = Subtract D1 from D2 and place the result in D3
[MUL D1 D2 D3] = Multiply " " " "
[DIV D1 D2 D3] = Divide
[ADD D1 D2 D3] = Add

The above are 16 bit math
to make them 32 bit you add a D infront of the math sigh (DSUB)
but this uses 2 consequetive D registers.

Hi Goody!
TQ for your help,it really helps. Can you advice me on some advance mathematic like mod, square, squareroot, area and volume calculation. Also some statistical intructions like min, variation and standard deviation.

Have a nice day.

As silva wrote - download the fx programming manual from his link.

You will find all the mathematical instructions there.
