Limitations when Using Index Registers
B-16 Data Registers
The sixteen Data Registers (DR0 to DR15) are used to offset the PLC memory addresses in Index Registers
when addressing words indirectly.
The value in a Data Register can be added to the PLC memory address in an Index Register to specify the
absolute memory address of a bit or word in I/O memory. Data Registers contain signed binary data, so a Data
Register containing a negative number will offset the content of an Index Register to a lower address.
Bits in Data Registers cannot be force-set and force-reset.

mands.
The Index Registers are not local to each task. Index Registers are shared by all tasks, including inter-
rupt tasks. In addition, the following limitations apply.
(1) The SRCH(181), MAX(182), and MIN(183) instructions can output the PLC memory address of the
(2) Index Registers IR00 and IR01 are used to pass argument data to a subroutine when the JUMP TO
word with the desired value (search value, maximum, or minimum) to IR0. In this case, IR0 can be
used in later instructions to access the contents of that word.
SUBROUTINE instruction (JSB(982)) is used. Be sure to avoid conflicts with IR00 and IR01 in pro-
grams that contain JSB(982).
