Studio 5000: Swap Byte in structure

[taylor1982]

Hello everybody,

I have a communication to a Linux-PC via sockets. So I created a quite large UDT with all the content.
Unfortunately we have to swap the low and highbyte. Of course there is the SWPB instruction. But it seems to me that this is not applicable for structures (?)

Can you give me some advices how to solve this?

Thanks a lot!

There is no easy way to solve your problem. You could store 2 copies of the UDT. One your store in the normal way and the other one swapped. This means two writes must be done when updating the UDT but then the swapped UDT doesn't have to have every word swap byte before sending. The swapped byte UDT can just be sent.
