Table Data Processing Instructions
Section 3-17
Description
SUM(184) adds C units of data beginning with the data in R1 and outputs the
result to D+1 and D. The settings in C+1 determine whether the units are
words or bytes, whether the data is binary (signed or unsigned) or BCD, and
whether to start with the right or left byte of R1 if bytes are being added.
When bit 14 of C+1 has been set to 0, SUM(184) treats the data as binary. In
this case, bit 15 determines whether the data is signed (bit 15 = 1) or
unsigned (bit 15 = 0).
When bit 13 of C+1 has been set to 1, SUM(184) adds bytes of data. In this
case, bit 12 determines whether the calculation starts with the rightmost byte
of R1 (bit 12 = 1) or the leftmost byte of R1 (bit 12 = 0).
Note SUM(184) can be processed in the background. Refer to the SYSMAC CS/
CJ/NSJ Series PLC Programming Manual (W394) for details.
