Programming Manual - Basic & Applied Instruction Edition
9 Move and Compare – FNC 10 to FNC 19
9.10 FNC 19 – BIN / Conversion to Binary
2. 32-bit operation (DBIN and DBINP)
This instruction converts the binary-coded decimal (BCD) data of [ +1, ] into binary (BIN) data, and
transfers the converted binary data to [ +1, ].
• The data of [ +1, ] can be converted if it is ranging from 0 to 99,999,999 (BCD).
• The table below shows digit specification for [ +1, ] and [ +1, ].

Cautions
1. When using DSW (FNC 72) instruction
Because conversion between binary-coded decimal data and binary data is automatically executed in DSW (FNC 72)
instruction, BIN instruction is not required.
2. Handling of BCD inputs and outputs
Binary data is used in all operations in PLCs including arithmetic operations (+, −, × and ÷), increment and decrement
instructions.
• When receiving the digital switch information in the binary-coded decimal (BCD) format into a PLC, use BIN (FNC
19) instruction for converting BCD data into binary data.
• When outputting data to the seven-segment display unit handling binary-coded decimal (BCD) data, use BCD (FNC
18) instruction for converting binary data into BCD data.
Error
When the data of is not binary-coded decimal (BCD), M8067 (operation error) turns ON. But M8068 (operation
error latch) does not turn ON.
