IEC_BMDI is available for M580 and Quantum after installing the UMAC library.

Unfortunately at this time it is not available for the M340. You will need to program your own. You could do something like %MW10:100 := %MW500:100; in ST or use a straight MOVE block with addressing such as this.

If you are trying to move between different data types of unlocated variable data, then you will need to incorporate some logic converting types back and forth. There are blocks COPY_AR.... that offer some move and convert.

*** If the M340 supports LL984 networks, they support both BLKM and BMDI ***
