Index Setting (1) Overview of the index setting (a) The index setting is an indirect setting that uses index registers. When the index setting is used in a sequence program, the device consists of ‘directly specified device number’ + ‘content of index register’. For example, when D2Z2 is specified and the value of Z2 is 3, D(2+3)=D5 is set as the target.

Page 85 (4) Applying index settings to extended data registers (D) and extended link registers (W) (for Universal model QCPU) As an index setting can be applied to internal user devices, data registers (D) and link registers (W), the device specification by the index setting can be used within the range of extended data registers (D) and extended link registers (W).
Page 86 2) Index settings that cross file registers (ZR), extended data registers (D), and extended link registers (W) Even when an index setting that crosses file registers (ZR), extended data registers (D), and extended link registers (W) is applied, an error does not occur.
Page 87 (b) An index setting is applicable to both I/O numbers and buffer memory numbers for intelligent function module devices U10Z1\G0Z2 If Z1=2 and Z2=8, then U(10+2)\G(0+8)=U12\G8 (c) An index setting is applicable to both network numbers and device numbers for link direct devices J1Z1\K4X0Z2 If Z1=2 and Z2=8,...
Page 88 (6) Precautions (a) Applying the index setting within the FOR to NEXT instruction loop The pulses can be output by using edge relays (V) within the FOR to NEXT instruction loop. Note that the pulses cannot be output by the PLS, PLF or pulse ( P) instruction.
Page 89 (b) Applying the index setting in the CALL instruction The pulse can be output by using edge relays (V) with the CALL instruction. Note that the pulse cannot be output by the PLS, PLF or pulse ( P) instruction. [When using an edge relay] [When not using an edge relay] (M0Z1 pulse is output normally.) (M0Z1 pulse is not output normally.)
Page 90: Precautions On Programming
Precautions on Programming The following cases cause an operation error during the execution of basic instructions and application instructions in a CPU module. • Errors described on each page of instruction explanation are occurred. • No intelligent function module is mounted at the specified I/O number position when an intelligent function module device is used.
Page 91 2) For Universal model QCPU The device range is checked. When the data exceed the corresponding device range, an operation error occurs. For example, when data registers are assigned in 12k points, an error occurs if the data exceed D12287. DMOV D12287 This specifies D12287 and D12288 as the...

Page 93 However, when the index setting is applied in the CPU module other than the Universal model QCPU, and if the start number of the device exceeds the device range, an error does not occur and the data accesses to another devices. When the data are accessed as following in the Universal model QCPU, an error occurs.
Page 94 Remark For the method for changing the assignment of internal user devices, refer to the following manual. • QCPU User's Manual (Function Explanation, Program Fundamentals) (d) When the index setting is applied to direct access output (DY), the device range is checked.

Page 96: Operation Of Out Instructions, Set/Rst Instructions, Or Pls/Plf Instructions Using Same Device
3.10 Operation of OUT Instructions, SET/RST Instructions, or PLS/PLF Instructions Using Same Device This section explains the operation when the OUT instructions, SET/RST instructions, or PLS/ PLF instructions that use a same device are executed multiple times in one scan. (1) OUT instructions that use a same device Avoid executing the OUT instructions that use a same device multiple times during one scan.
Page 97 (2) SET/RST instructions that use a same device (a) The SET instruction turns ON the specified device when the execution command is ON, while it performs no operation when the execution command is OFF. Thus, if the SET instructions that use a same device are executed multiple times during one scan, the specified device is turned ON when any of the execution commands is turned ON.
Page 98 (3) PLS instructions that use a same device The PLS instruction turns ON the specified device when the execution command turns from OFF to ON. When the status is other than turning from OFF to ON, (OFF to OFF, ON to ON or ON to OFF), the PLS instruction turns OFF the specified device.
Page 99 • The timings of turning from OFF to ON between X0 and X1 are same EN ENO EN ENO EN ENO EN ENO M0 turns OFF because X1 status is M0 turns ON because X1 other than OFF goes ON (OFF ON).

(1) Setting file registers to be used To use file registers, they need to be set in the PLC parameter or the QDRSET instruction. If the file registers are not set, normal operations cannot be performed in the instructions that use the file registers.
Page 102 (3) Specifying the file register number exceeding the registered number (a) For CPUs other than Universal model QCPU An error does not occur when data are written/read to/from the file register numbers that are greater than the registered number of points. Note that the data cannot be written/read correctly to/from file registers.
