Compactlogix SINT-DINT

[Christoph]

I am working on a new Compactlogix application
for a slitting winding machine, converting from relay
and circuit board analog controls to Compactlogix.
I am using a Profibus encoder for position feedback
of the winding arms to calculate roll diameter.
The GSD file for the encoder places the data in
2 words of a data array (SINT). Can these 2 words
be combined into a single (DINT).

Depending on byte order, it may be as simple as:
COP TheSINT[0] MyINT 1
MOV MyINT MyDINT

I suggest copying into an intermediate integer, as if you COP directly into a DINT, it will grab 4 bytes instead of 2, and might have garbage.

Thanks! I will try it out here shortly.
