Hello Ganesh; If by Long you mean a double-integer (32-bit), then conversion from a REAL is done with round ou Trunc instructions. If you mean 64-bit registers, then you should look at the freeOSCAT.de library for S7, they have instructions to handle these registers. Noe, when you mention "swapped", if you mean shifting the bytes inside a register, look at STL instructions CAW (16-bit) and CAD (32-bit): http://support.automation.siemens.com/WW/view/en/45523446 Hope this helps, Daniel Chartier |
