1
Sum BCD Numbers sums up a list of consecutive 4-digit WORD BCD numbers into an 8-
digit DWORD BCD result.
230
2
You specify the group's starting and ending
240
V-memory addresses (inclusive). When
enabled, this instruction will add up all the
250-1
3
numbers in the group (so you may want to
260
place a differential contact driving the
4
enable).
DS5 Used
SUMBCD could be used as the first part of
N/A
HPP
