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).
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.
When enabled, this instruction will add 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
