Designation of modification values in index modification of entire
ladders
IXDEV, IXSET
Processing details
• The IXDEV and IXSET instructions are used to configure an index modification table used in the IX and IXEND instructions.
• The device offset value designated at the offset designation area is set at the index modification table designated by (D).
• The value 0 will be entered if no designation is made.
• Word devices are also indicated by contact (word device bit designation). Data register 10 (D10) is designated with D10.0.
(Any value from 0 to F can be used for the bit number.)
• Designation is made according to the method described below.
*1
(The symbol  is where the offset value will be. The
notation XX indicates random selection.)
*1 When using a basic model QCPU, the devices R, U/G, J, ZR and P cannot be used.
*2 Devices following J\ designate B, W, X, or Y, and the offset value is also set in correspondence with this.
*3 When using a basic model QCPU, specify a dummy device number.
(S) is P.
(S): Head number of the devices where index modification data is stored (pointer only) P (Pointer)
(D): Head number of the devices where index modification data will be stored (except a pointer) (BIN 16 bits)
