[N/B] Parameters |
N1 or B1 |
Not used, leave it in 0 (zero) |
N2 or B2 |
Data Type and Area. This value must be composed by the sum of a data type plus an Area. If the value of a data type is equal to 0 (zero), then assumes the basic data type of that Area |
N3 or B3 |
Special usage parameter. Leave it in 0 (zero) if the address in an Area, or offset, is less than 65535 and there is no need to inform the size if a data type is equal to a String. Otherwise, please check topic Using the N3 or B3 Parameter |
N4 or B4 |
Value of the address in an Area, or offset, for values up to 65535. For greater values, please check topic Using the N3 or B3 Parameter |

NOTES |
•The default data type of Areas 18, 19, 20, 21, 23, 24, 25, 26, 27, and 33 is a Word (unsigned 16-bit) and does not accept being configured as a Bit data type. •The default data type of Areas 30 and 36 is a Double Word (unsigned 32-bit) and does not accept being configured as a Bit data type. •The default data type of all other Areas is a Bit. |
Value |
Meaning |
|---|---|
000 |
Basic data type of this Area (Bit or Word) |
100 |
Bit (value 1 or 0) |
200 |
Word value (unsigned 16-bit) |
300 |
Short value (signed 16-bit) |
400 |
Double Word value (unsigned 32-bit) |
500 |
Long value (signed 32-bit) |
600 |
Floating Point value (32-bit floating point, IEEE 754) |
700 |
Double Floating Point value (64-bit double precision floating point, IEEE 754) |
800 |
BCD value (16-bit) |
900 |
Long BCD value (32-bit) |
1000 |
32-bit value |
1100 |
Sequence of String characters |
NOTE |
Only PLC Tags configured for Areas Data Register, Link Register, or File Register support the String data type. Block Tags or Tags configured with different Areas do not support the String data type. |
1.Reading or writing an Input with address 1 (one) and a default Bit data type: The N2 parameter equal to 0 (zero), the N3 parameter equal to 0 (zero), and the N4 parameter equal to 1 (one). If the N2 parameter is equal to "100", then the result is the same.
2.Reading or writing an Output with address 100 and data type configured as Word: The N2 parameter equal to 202, the N3 parameter equal to 0 (zero), and the N4 parameter equal to 100.
3.Reading or writing a Counter Value with address 50 and a default Word data type: The N2 parameter equal to 20, the N3 parameter equal to 0 (zero), and the N4 parameter equal to 50. If the N2 parameter is equal to "220", then the result is the same.
4.Reading or writing a Data Register with address 1000 and data type configured as Double Word: The N2 parameter equal to 421, the N3 parameter equal to 0 (zero), and the N4 parameter equal to 1000. The value from 2 (two) contiguous Data Registers starting at address 1000 is reinterpreted as a Double Word value.
