Function Tables
Purpose
Simplifying Creating looped program
the Program sections.
Indirectly addressing DM
words.
Simplifying the program by
switching to PLC memory
address specification.
Consolidating instruction
blocks with the same pat-
tern but different addresses
into a single instruction
block.
Function
Use FOR(512) and NEXT(513) or
JMP(004) and JME(005).
All words in the DM and EM Areas can
be indirectly addressed.
Use Index Registers as pointers to
indirectly address data area
addresses.
The Index Registers are very useful in
combination with loops, increment
instructions, and table data process-
ing instructions. The auto-increment,
auto-decrement, and offset functions
are also supported.
Use function blocks (FBs).
Use MCRO(099).
