Operation description
Converts the decimal numeric value in LDR200 to a string and stores it in order with LDR100 as the starting address number.
Converting 1234 (when the data type is UBIN16(W))
Converting -12345 (when the data type is BIN16(I))
Converting 1234567890 (when the data type is UBIN32(D))
Converting -1234567890 (when the data type is BIN32(L))
■ Example 5.7.20 Convert decimal to string
DEC2ASCII([LDR 100], [LDR 200]);
• This function can only be configured when UBIN16(W) , BIN16(I) , UBIN32(D) , BIN32(L) , BCD4(B)
or BCD8(EB) is specified as the Data Type .
• You can only specify an internal device.
• When using functions that handle strings, check the
Storage Method of string data setting on the
System tab in the Project Settings dialog box. Depending on the setting, the upper and lower bytes
are stored in the reverse of the following explanation. For details, refer to Chapter 4 “3.1 System Tab” on
page 4-25.
• A NULL terminating character (0x00) is added to the end of the string.
