(2) Replacement example of the IXDEV and IXSET instructions
A replacement example of program using the IXDEV and IXSET instructions is shown
below.
Change the program so that the device offset value specified by the contacts between
the IXDEV and the IXSET instructions are directly set to the index modification table
using the MOV instruction.
For the devices whose device offset value is not specified by the IXDEV and IXSET
instructions, set the device offset value to 0 in the program after replacement. The
following shows how the device offset value is set in the program before and after
replacement.
* 1: Device numbers are expressed in hexadecimal. Use hexadecimal constants (H ) when setting
values in the index modification table.
* 2: Start I/O numbers (U ) are expressed in hexadecimal. Use hexadecimal constants (H ) when
setting values in the index modification table.
* 3: Devices B, W, X or Y can be specified following J\. Set device numbers for B, W, X, and Y as
device offset values of each device in the index modification table.
For example, if "J10\Y220" is specified by the IXDEV and IXSET instructions, set "K10" in (D)+13
and "H220" in (D)+3 in the replacement program. ((D) indicates the start device in the index
modification table.)
