Page 82: Using Character String Data
3.2.5 Using character string data Character string data is character data used by basic instructions and application instructions. The target ranges from the designated character to the NULL code (00 ) that indicates the end of the character string. (1) When designated character is the NULL code One word is used to store the NULL code.
Page 83 Indexing (1) Overview of indexing Indexing is an indirect setting made by using an index register. When an Indexing is used in a sequence program, the device to be used will become the device number specified directly plus the contents of the index register. For example, if D2Z2 has been specified, the specified device is calculated as follows: D(2+3) = D5 and the content of Z2 is 3 become the specified device.
Page 84 2) Devices with limits for use with index registers Device Meaning Application Example T0Z0 K100 • Only Z0 and Z1 can be used for T1Z1 timer contacts and coils. C0Z1 K100 • Only Z0 and Z1 can be used for C1Z0 counter contacts and coils.

SM400 SM400 X0Z1 V0Z1 X0Z1 M0Z1 M0Z1 SM400 SM400 NEXT NEXT Remark The ON/OFF data of X0Z1 is stored by the edge relay V0Z1. For example, the ON/OFF data of X0 is stored by V0, and that of X1 by V1.
Page 86: Indirect Specification
Indirect Specification (1) Indirect Specification (a) Indirect specification is a method that specifies address of the device to be used in a sequence program using two word devices (two points of word device). Use indirect specification as index modification when the index register is insufficient. Stores the address of ADRSET D100...
Page 87 (3) Precautions (a) The address for indirect specification uses two words.Therefore, to substitute indirect specification for index modification, the addition/subtraction of 32-bit data is required. The following is the ladder used for the address addition/subtraction of the device stored in D1 and D0 for indirect specification. [To add "1"...

For example, when 12 k points are assigned to a data register, an error occurs if the device number of the data register exceeds D12287.
Page 92 Remark Refer to the manuals below for how to change the internal user device allocation: • QnACPU Programming Manual (Fundamentals) (d) Device range checks are conducted when indexing is performed by direct access output (DY). (2) Device data check Device data checks for the devices used by basic instructions and application instructions in CPU module are as indicated below: (a) When using BIN data No error is returned even if the operation results in overflow or underflow.
Page 93: Conditions For Execution Of Instructions
Conditions for Execution of Instructions The following four types of execution conditions exist for the execution of CPU module sequence instructions, basic instructions, and application instructions: • Non-conditional execution..Instructions executed without regard to the ON/OFF status of the device Example LD X0, OUT Y10 •...
Page 94: Counting Step Number
Counting Step Number The number of steps in CPU module sequence instructions, basic instructions, and application instructions differs depending on whether indirect setting of the device used is possible or not. (1) Counting the number of basic steps The basic number of steps for basic instructions and application instructions is calculated by adding the device number and 1.
Page 95 Operation when the OUT, SET/RST, or PLS/PLF Instructions Use the Same Device The following describes the operation for executing multiple instructions of the OUT, SET/RST, or PLS/PLF that use the same device in one scan. (1) OUT instructions using the same device Do not program more than one OUT instruction using the same device in one scan.
Page 96 (2) SET/RST instructions using the same device (a) The SET instruction turns ON the specified device when the execution command is ON and performs nothing when the execution command is OFF. For this reason, when the SET instructions using the same device are executed two or more times in one scan, the specified device will be ON if any one of the execution commands is ON.
Page 97 (3) PLS instructions using the same device The PLS instruction turns ON the specified device when the execution command is turned ON from OFF. It turns OFF the device at any other time (OFF to OFF, ON to ON, or ON to OFF). If two or more PLS instructions using the same device are executed in one scan, each instruction turns ON the device when the corresponding execution command is turned ON from OFF and turns OFF the device in other cases.
Page 98 • The X0 and X1 turn ON from OFF at the same time. M0 turns ON because X1 M0 turns OFF because X1 status is other than OFF goes ON (OFF ON). (M0 remains OFF.) (M0 remains ON.) M0 turns ON because M0 turns OFF because X0 status is other X0 goes ON (OFF ON).
Page 99 [Timing Chart] • The ON/OFF timing of the X0 and X1 is different. (The specified device does not turn ON throughout the scan.) M0 turns OFF because X1 status is M0 turns OFF because X1 other than ON OFF. status is other than ON OFF.

3.10 Precautions for Use of File Registers This section explains the precautions for use of the file registers in the QnACPU. (1) Setting of file registers to be used When using the file registers, the file registers to be used must be set with the PLC parameter or QDRSET instruction.
Page 101 (4) File register specifying method There are the block switching method and serial number access method to specify the file registers. (a) Block switching method In the block switching method, specify the number of used file register points in units of 32k points (one block).
Page 102 (b) Restrictions The restrictions when specifying file registers to refresh devices are as follows. 1) Refresh cannot be performed correctly if the use of file register which has the same name as the program is specified by the PLC parameter. When the file register which has the same name as the program is used, refresh is performed to the data of the file register having the same name as the program that is set at the last number in the [Program] tab page of PLC...

INSTRUCTIONS FOR DATA LINK Reference Category Processing Details section Network refresh instructions Section 8.2 Refreshes the specified network module. Section 8.3.1 Reading the QnACPU device data from target station of target network number. Section 8.3.2 Section 8.3.3 Writing data to the QnACPU device of target station of target network number.
Page 634: Overview
Overview QnACPU allows the data link using MELSECNET/10, Ethernet, MELSECNET (II,/B), CC-Link, and serial communication. The instructions for data link are instructions that allow the CPU to read data to the host station from other stations connected to the CC-Link IE controller network, MELSECNET/H, MELSEC- NET/10 or MELSECNET (II,/B).
Page 635 (2) Reading/wring range of data (a) With CC-Link IE controller network, MELSECNET/H and MELSECNET/10, the host station can read/write data not only from/to connected stations in the same network, but also from/to connected stations in the other networks. (1) Reading/writing data from/to connected stations in the same network The network number set to the target station must be the same network number set to the host station.
Page 636 The device of the other station CPU module that reads/writes according to instructions for data link must be specified within the device range applicable to the host station CPU module. Care must be taken when the applicable device range differs between the other station CPU module and the host station CPU module.
Page 637 (b) Arrival confirmation When sending by the QnA link dedicated instructions, 'With/Without arrival confirmation' can be set. (When reading by QnA link dedicated instructions, only 'With arrival confirmation' can be set.) • With arrival confirmation : Instruction is completed when data is written to a specified channel of a specified target station.
Page 638 (4) Network module channels (a) For SEND, RECV, READ, WRITE, REQ, ZNRD, ZNWR, SREAD or SWRITE instruction The network module has eight channels to execute instructions. Eight channels can be used at once, but the same channel cannot be used by multiple instructions.
Page 639 (5) Overview of each instructions The following explains the instructions that can be used for the QnACPU. Channels 1 to 8 are common areas for SEND / RECV / READ / WRITE / REQ / SREAD / SWRITE instructions. Instruction Execution Station Target Station (Host Station) Meaning...

Page 644 ZCOM (4) Remote I/O network The link refresh of the remote master station is performed by the "END processing" of the CPU module. Since link scan is performed at completion of link refresh, link scan 'synchronizes' with the program of the CPU module. When the ZCOM instruction is used at the remote master station, link refresh is performed at the point of ZCOM instruction execution, and link scan is performed at completion of link refresh.
