Hey guys,

I'm having some trouble declaring the variables in my project.
I want to be able to set/reset the bits in a word and be able to reset the whole word at once.
So far i got it working fine at %MW0, but when I try the same at any other adress it wont work.

Can somebody help me a bit?

Try:

MyMW:pointer to dword;

MyMW:=adr(mx0);

MyMW[0] is mx0
MyMW[1] is mx1
.
.
.

Setting full

MyMW[1]:=16#B1

For example

I think a Union of 16 BITs (not BOOL) and a WORD is a better way to achieve this.

Thank you for the suggestions guys! A union seems to work quite well.

How do I add a comment to a bit in a union?

For example: bit 1 in union 1 should be called "valve 5". And bit 1 in union 2 should be named different.

Include a STRUCT in your union with the names you need. It sounds like this can replace the BITs

When I re-use a union by declaring the same union under different name. Then the bits will have the same name, right?

Maybe my intentions aren't clear:

For my program i need my bits in groups of 16, like a word. I want to set/reset these bits individually or all at once.
I need a whole bunch of these groups. I'd like to add a comment to every individual bit in a group. (With different comments in different groups)
A fixxed adress is not necessary.

I need a fast/simple method of creating these groups

This is what I've done so far:

TYPE STR_BITS :
STRUCT
   x00 : BIT;
   x01 : BIT;
   x02 : BIT;
   x03 : BIT;
   x04 : BIT;
   x05 : BIT;
   x06 : BIT;
   x07 : BIT;
   x08 : BIT;
   x09 : BIT;
   x10 : BIT;
   x11 : BIT;
   x12 : BIT;
   x13 : BIT;
   x14 : BIT;
   x15 : BIT;
END_STRUCT
END_TYPE

TYPE UNION_BITS_WORD :
UNION
   strBits : STR_BITS;
   wWord : WORD;
END_UNION
END_TYPE

VAR
   union1 : UNION_BITS_WORD;    
   union2 : UNION_BITS_WORD;    
END_VAR

I like the way how its working now with the struct and the union.
Can somebody explain how I add a comment to one specific bit in one specific word?

Something along the lines of this?

GVL.W120.Wstruct.x00 // Word 120, Bit 00, Valve 5
