Pack 2 Bytes into 1 Word Micrologix 1500LRP

I am working on an RFID project that will write Micrologic integer value to an RFID tag. The RFID system is the Turck BLCDN RFID SLICE. It communicates via Devicenet. I have mapped it to the scanner and all works well. It will allow me to write and read 4 words with no issues. The problem is that I need to write and read at 5 values. Two of the word values are under (255 decimal, hence 1 BYTE). If I could pack these 2 values as one word I believe this would solve my issue. Long story short can anyone help me on how to pack 2 Byte's into 1 Word on the Micrologix 1500LRP. I will also need to unpack them when I read the RFID tag.
Any help would be much appreciated.
Thanks

One approach would be to use the SWP instruction to swap the low and high bytes of one of the words, which would put the 8 data bits on the high end and 8 zeros on the low end. Then use a masked move MVM or OR instruction to combine the swapped word with the remaining value, and you'd have two 8-bit values stored in one 16-bit word. I've never personally used the SWP instruction but after reading the help file it seems like it should work.

Here is a working example.

Thanks, Ill try it the morning.
