Cautions
1) When handling array data or 32-bit data in a structured program, a 16-bit device cannot be specified
directly as in the case of a simple project. Use a label to handle array data or 32-bit data.
A 32-bit counter can be specified directly as it is a 32-bit long device.
Use a global label to specify a device
2) The FX
3UC PLC of V 2.20 or later supports the DABIN instruction.
3) Occupied device points
The table below shows the occupied device points of the device specified by for 16-bit operation
(BINDA/BINDAP) when M8091 is ON or OFF and 32-bit operation (DBINDA/DBINDAP).
Error
An operation error is caused in the following cases. The error flag M8067 turns ON, and the error code is
stored in D8067.
1) When the occupied device points of the ASCII code character string in the device specified by
exceed the corresponding device range. (Error code: K6706)
Device Name Description
M8091
Output character quantity
selector signal
• For 16-bit operation
- When M8091 is OFF, + 3 is set to "0000H (NULL)".
- When M8091 is ON, + 3 does not change.
• For 32-bit operation
- When M8091 is OFF, the high-order byte of + 5 is set to "00H (NULL)".
- When M8091 is ON, the high-order byte of + 5 is set to "20H (space)".
Instruction Description
ASCI Converts hexadecimal codes into ASCII codes.
HEX Converts ASCII codes into hexadecimal codes.
DESTR Converts binary floating point data into a character string data (ASCII code) with the specified number of digits.
DEVAL Converts character string data (ASCII code) into binary floating point data.
DABIN Converts numeric value data expressed in decimal ASCII codes (30H to 39H) into binary data.
