Table Data Processing Instructions Section 3-17
Flags
Precautions When bit 15 of C+1 has been set to 1, the data within the range is treated as
signed binary data and hexadecimal values 8000 to FFFF are considered
negative. Thus, the results of the search will differ depending on the data-type
setting.
If background execution is enabled in the PLC Setup, the PLC memory
address of the word containing the maximum value will be output to Auxiliary
Area words A595 and A596 instead of IR00.
Examples When CIO 000000 turns ON in the following example, MAX(182) searches
the 10-word range beginning at D00200 for the maximum value. The maxi-
mum value is written to D00300 and the PLC memory address of the word
containing the maximum value is written to IR00.
Name Label Operation
