FILL(V1, V2, V3) means to fill address V1 with data in address V2 and the data number is V3. If the block length is more than internal memory or maximum number of PLC address, there will be error occurred when compiling.

Example:

$5 = 10

FILL($0, $5, 4)

Executing FILL command to fill $0, $1, $2, $3 with constant 10.

„CHR

Convert Text to ASCII code

Equation: CHR(V1, "V2")

CHR(V1, "V2") means to convert text in address V2 to ASCII code and store in V1. The maximum length is 128 words. One address can store up to two words. The excess word will be stored in next address in order. The low and high bit of the converted ASCII code will be exchanged.

Example:

CHR($1, "AB12")

After executing CHR command, 4241H will be stored in $1 and 3130H will be stored in $2.

„FMOV

Transfer Floating Point Data

Equation: V1 = FMOV(V2) (Signed DW)

Transfer floating point data from V2 to V1. No data change within V2 after the command is executed.

Example:

Transfer constant 44.3 to the internal memory address $0. $0 = FMOV(44.3) (Signed DW)

Transfer the same data of PLC 1@C200 to the internal memory address $0. $0 = FMOV(1@C200) (Signed DW)

„Data Conversion

Command	Equation	Description
BCD	V1 = BCD(V2)	Converts BIN Data into BCD
BIN	V1 = BIN(V2)	Decimal value conversion
W2D	V1 = W2D(V2)	Convert WORD to DWORD
B2W	V1 = B2W(V2, V3)	Convert BYTE to WORD
W2B	V1 = W2B(V2, V3)	Convert WORD to BYTE
SWAP	SWAP (V1, V2, V3)	Swap BYTE data of the WORD
XCHG	XCHG (V1, V2, V3)	Exchange data
