5.3 Character Strings



Character Strings



Character strings are classified into character string constants which directly specify character strings in operands in

applied instructions and character string data.



5.3.1



Character string constant ("ABC")

A device "character string" directly specifies a character string in a sequence program.

Put half-width characters inside quotation marks (example: "ABCD1234") in specification.

JIS8 code is available.

Up to 32 characters can be specified as a character string.



5.3.2



Character string data

With regard to character string data, a specified device to the NULL code (00H) is handled as one character string in

1-byte units.

When expressing (recognizing) character string data by bit devices with digit specification, however, 16 bits are

required for data including the NULL code (00H) specifying the end of the character string data because the instruction

length is 16 bits. (Refer to Example 2 in the step 2 below.)

In the following cases, an operation error occurs in the applied instruction (error code: K6706):

• When "00H" is not specified in the corresponding device range after the source device number specified in an

applied instruction

• When there are insufficient devices for storing character string data (including "00H" or "0000H" indicating the end

of the character string data) in the destination devices specified in an applied instruction

When 16-bit data is transferred to K1M0 to K3M0, the highest-order bits are not transferred due to insufficient data

length.

32-bit data is transferred in the same way.

When the number of digits specified for bit devices is K1 to K3 (or K1 to K7) in a 16-bit (or 32-bit) operation, the

insufficient high-order bits are always regarded as "0". It means that such data is always positive.

Overview



Devices which handle only the ON/OFF information such as X, Y, M and S are called bit devices.

On the other hand, devices handling numeric values such as T, C, D and R are called word devices.

Even bit devices can handle a numeric value when they are combined. In this case, the number of digits Kn and the

head device number are combined.

The number of digits is expressed in 4 bit units (digits); K1 to K4 are used for 16-bit data, and K1 to K8 are used for 32bit data.

For example, "K2M0" indicates two-digit data expressed by M0 to M7.

Basic

Instruction



A series of data registers starting from D1 means "D1, D2, D3, D4 ....."

In the case of word devices with digit specification, when such word devices are handled as a series, they are

specified as shown below:



Before

Programming



A bit device number can be specified arbitrarily, but it is recommended to set the least significant digit to "0" for X or Y.

(In other words, it is recommended to specify "X000, X010, X020 ... Y000, Y010, Y020 ...")

For M and S, multiples of "8" are ideal, but it is recommended to specify "M0, M10, M20 ..." to prevent confusion.



Use the above devices in digit units so that devices are not skipped.

When "K4Y000" is used in a 32-bit operation, the high-order 16 bits register as "0".

It is necessary to use "K8Y000" when 32-bit data is required.

Direct Specification of Buffer Memory (U[ ]\G[ ])



A buffer memory (BFM) of a special function units/blocks can be specified directly.

BFM is 16-bit or 32-bit word data, and is mainly used for operands in applied instructions.

For specifying a BFM, specify the unit number (U) of a special function units/blocks and the BFM number (\G)

consecutively.

(Example: U0\G0 ... Indicates the BFM #0 in the special function units/blocks whose unit number is 0.)

Indexing is available for BFM numbers.

The specification range is as follows:

It is not permitted to use 16-bit counters as 32-bit counters by

When an octal device number of X or Y is indexed with an index

register, the contents of the index register are converted into octal, and then added to the device number.

For example, when the value of an index register added to the input X000 is changed in the order "K0 → K8 →

K16", the device number converted into octal is added to the input X000 and the input number is changed in the

order "X(000+0) = X000 → X(000+8) = X10 → X(000+16) = X20".

Transfer K0 or K10 to the index register V1 in advance.

When X001 is set to ON, "M(0+0) = M0" and the comparison result is

output to M0 to M2 if V1 is "0".

On the other hand, "M(0+10) = M10" and the comparison result is output

to M10 to M12 if V1 is "10".

destination D0 in MOV instruction is indexed with the index register V3 (as

shown in the figure on the right).

Transfer K0 or K10 to the index register V3 in advance.

When X001 is set to ON, "D(0+0) = D0" if V3 is "0", and K500 is

transferred to D0.

When X001 is set to ON, "D(0+10) = D10" if V3 is "10", and K500 is

2. indexing operands in 32-bit instructions

In a 32-bit instruction, it is also necessary to specify a 32-bit index register

in the instruction.

When an index register Z (Z0 to Z7) is specified in a 32-bit instruction, the

specified Z and its counterpart V (V0 to V7) work together as 32-bit

registers.

The indexing operation is explained in an example in which the transfer

destinations [D1, D0] in DMOV instruction are indexed with the index

registers [V4, Z4] (as shown in the figure on the right).

Transfer K0 or K10 to the index registers [V4, Z4] in advance.

When X003 is set to ON, "[D(1+0), D(0+0)] = [D1, D0]" if [V4, Z4] is "0",

and K69000 is transferred to [D1, D0].

When X003 is set to ON, "[D(1+10), D(0+10)] = [D11, D10]" if [V4, Z4] is

"10", and K69000 is transferred to [D11, D10].

1)



When even if a numeric value written to index registers does not exceed the 16-bit numeric value range (0 to

32767), make sure to overwrite both V and Z using a 32-bit instruction. If only Z is overwritten and another

numeric value remains in V, the numeric value will be extremely large. Thus an operation error occurs.



2)



It is not permitted to use 16-bit counters as 32-bit counters by executing indexing.

When 32-bit counters are required, add Z0 to Z7 to counters C200 and later.

3)



It is not permitted to index V and Z themselves.



4)



Direct specification of buffer memory in special function units/blocks

In the direct specification of buffer memory "U \G ", the buffer memory number can be indexed with index

registers.

The unit number cannot be indexed with index registers.

("U0\G0Z0" is valid, but "U0Z0\G0" is invalid.)

Introduction



Cautions



5)



Indexing in bit digit specification

It is not permitted to index "n" in "Kn" used for digit specification.

("K4M0Z0" is valid, but "K0Z0M0" is invalid.)



6)



Indexing of I/O relays (octal device numbers)

When octal device numbers of X, Y, KnX, and KnY are indexed with

index register, the contents of an index register are converted into

octal, and then added to the device number.

In the example shown in the figure on the right, Y007 to Y000 are

output by MOV instruction, and inputs are switched by indexing X007

to X000, X017 to X010, and X027 to X020.

When rewriting the index value as "K0", "K8", "K16", the device

number converted into octal is added "X000 + 0 = X000", "X000 + 8 =

X10", "X000 + 16 = X20", and the input terminal working as the

source is changed accordingly.

5.7 Indexing



Indexing example for instruction with limited number of use.

By modifying the target device numbers using index registers V and Z, the target device numbers can be changed

using the program. In this way, an instruction with a limited number of uses per program can be used with multiple

devices.

Example using the TKY instruction (FNC 70)

Two groups of key entries (numeric keypad from 0 to 9)

store the input data to D0 and D2. Although the TKY

instruction (FNC 70) can only be programmed once,

modifying the head device number of the input data,

storage destination and pressed key information, the

information can be input from the two groups of keys

(numeric keypad from 0 to 9). Furthermore, even if V is

changed while this instruction is being executed, this

change is invalid.

The change is invalid until the instruction is no longer

being driven.
