Sum Real Numbers (SUMR) (IB-542)
Sum Real Numbers sums up a list of consecutive REAL DWORD numbers into a REAL
DWORD result.
You specify the group’s starting and ending V- memory addresses (inclusive).
When enabled, this instruction will add up all the numbers in the group (so you may want to
place a differential contact driving the enable).
SUMR could be used as the first part of calculating an average.
SUMR Parameters
• Start Address (DWORD): specifies the starting address of a block of V-memory location values to be
added together (Real)
• End Addr (inclusive) (DWORD): specifies the ending address of a block of V-memory location
values to be added together (Real)
• Result (DWORD): specifies the location where the sum of the block of V-memory Real values will
be placed
Parameter DL06 Range
Start Address (inclusive DWORD) V See DL06 V-memory map - Data Words
End Address (inclusive DWORD) V See DL06 V-memory map - Data Words
Result (DWORD) V See DL06 V-memory map - Data Words
DS Used

N/A
Remember that Real numbers are DWORDs
and occupy 2 words of V-Memory each, so
the number of Real values summed up is equal
to half the number of memory locations. Note
that the End Address can be EITHER word of
the 2 word ending address, for example, if you
wanted to add the 4 Real numbers stored in
V2000 thru V2007 (V2000, V2002, V2004,
and V2006), you can specify V2006 OR
V2007 for the ending address and you will get
the same result.
