Cautions
1. When using SEGL (FNC 74) or ARWS (FNC 75) instruction
Because conversion between binary-coded decimal data and binary data is automatically executed in SEGL (FNC 74)
and ARWS (FNC 75) instructions, BCD 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.
Errors
In BCD or BCDP (16-bit type) instructions, an operation error occurs when the
0 to 9999.
In DBCD or DBCDP (32-bit type) instructions, an operation error occurs when the
from 0 to 99,999,999.
