Siemens conversion question...

[leem2209]

Hmmm I tried BLKMOV and could move into, say, QB0, or QW0 or QD0 but any more than that I couldn't work out. EG, BLKMOV DB101.DBX0.0, 500 bits into Q0. Doesn't like it...

 

[Lare]

P#M0.0 BYTE 10 SFC20 P#Q0.0 BYTE10 should move 80bits to outputs

What is size of process image on CPU properties, under 500?

 

[L D[AR2P#0.0]]

SFC20 requires that bools are multiples of 8 (500 is not)
Click on SFC20 then press F1 to read the help and error code definitions.

Ah.... ok.

I need to use P#...

I'll give this a try. it doesn't have to be 500, I can round it up/down to a set number of bytes (and probably will to keep a tidy structure in my data block), 500 was just a random number of bits I'm using for testing.

Lare & L D[AR2,P#0.0] to my rescue again!
