2151 Series Weight Controller.
Move Word 1 (MOVW1) selects the Block to Read, in this case 20 (14 hex) - Full
Status and Weight Data. Block 20 (14 hex) has 15 words, therefore the data is
transferred to WX1 through WX15.
K1: Contains hex 5400 (Block 84: Select Read Summary Data)
K2: Contains hex 1400 (Block 20: Full Status and Weight Data - The block
number to read)
C1: When C1 is ON, Block Read 20 information is read to WX1-WX15
MOVW1: Downloads the information in K1 and K2 into WY17 and WY18 (weight
controller)
Data is read to WX1 - WX15
