Designates indexing value.
*1: n indicates number of arguments for subroutine program.
*2: n indicates the total of the number of arguments used in the subroutine program and the number of program
name steps. The number of program name steps is calculated as "number of characters in the program/2"
(decimal fraction is rounded up).

Processing Details
• Performs non-execution processing of
subroutine program Pn if input
conditions have not been met. (S1 to
Sn are arguments sent to subroutine
program. N 5)
• Executes subroutine program Pn when
input condition is met.
• Performs non-execution processing of
subroutine program Pn if input
conditions have not been met. (S1 to
Sn are arguments sent to subroutine
program. N 5)
• Performs auto refresh of intelligent
function modules, link refresh, auto
refresh of CPU shared memory, and
communications with peripherals.
• Performs auto refresh of intelligent
function modules, auto refresh of CPU
shared memory, and communications
with peripherals after the input
conditions are met.
• Perform indexing for individual devices
used in device indexing ladder.
• Stores indexing value used for indexing
IX
performed between the and
to the device designated by D or later.
