Sum BCD Numbers (SUMBCD) (IB-522)
Sum BCD Numbers sums up a list of consecutive 4-digit WORD BCD numbers into an
8-digit DWORD BCD result.
You specify the group’s starting and ending V-memory addresses (inclusive). When enabled,
this instruction will add all the numbers in the group (so you may want to place a differential
contact driving the enable).
SUMBCD could be used as the first part of calculating an average.
SUMBCD Parameters
• Start Address: specifies the starting address
of a block of V-memory location values to
be added together (BCD)
• End Addr (inclusive): specifies the ending
address of a block of V-memory location
values to be added together (BCD)
• Result (DWORD BCD): specifies the
location where the sum of the block of
V-memory BCD values will be placed
SUMBCD Example
In the following example, the SUMBCD instruction is used to total the sum of all BCD values
in words V2000 thru V2007 and store the resulting 8-digit double word BCD value in V3000
and V3001 when C100 turns on.
