IX,IXEND
(2) Index modification for device numbers is accomplished in the manner as below: By setting a
modification value to each of the devices, the set modification values are added to the all
device numbers of the devices used in the ladder between the IX and IXEND instructions.
The program is executed using the index modified device numbers.

(3) Instructions such as the PLS, PLF, and
when input conditions have been established, cannot be index modified by using the IX to
IXEND instruction loop.
(4) In cases where adding the modification value causes the device number to exceed the
device range, accurate processing will not be conducted.
(5) Do not execute the IX or IXEND instructions during online program changes of sequence
programs (write during RUN). Accurate processing will not be conducted if this happens.
(6) Modification values are preset for random word devices as BIN values, and the initial device
number for which modification values have been set is designated by
(7) Do not execute a scan execution type program and an interrupt program simultaneously
between the IX and IXEND instructions.
