9. RSSS Remote I O System Once you have written all of the logic to map the starting addresses and point totals for each remote base you have to zero out all of the reserved memory locations you are not going to use and then tell the CPU that you are finished with the setup If you don t insert zeros in the unused areas the CPU will assume that every pointer address V37714 through V37736 is pointing to a read or write start address This could cause problems you may have garbage in these locations At the very least it oO O fd or veone TE o Qr op LO op Ga act gt DX Ne m will take up unnecessary scan time The most efficient method for zeroing out the unused memory is to use LDD and OUTD instructions load and store double to clear two consecutive memory locations at a time The following logic shows how to finish the setup program for this example First scan relay contact SPO I There are 20 unused reserved memory locations SPO LDD KO OUTD v37714 _ 0u V37716 OUTD V37720 OUTD V37722 OUTD V37724 OUTD V37726 OUTD V37730 OUTD V37732 _ OuTD V37734 OUTD V37736 C740 Load 32 bit accumulator with O Where the unused memory starts Clear all unused V memory locations 2 locations at a time __ ser Tell CPU that setup is completed
