Description
Operation using the TBCD instruction
When input relay 0000 turns ON, the contents of DM0000 are transferred to the
internal register. The contents of the internal register (16-bit binary data) are con-
verted into 4-digit BCD data, which is input back to the internal register, and then
transferred to DM0001.
Operation using the TBIN instruction
When input relay 0001 turns ON, the contents of DM0010 are transferred to the
internal register. The contents of the internal register (4-digit BCD data) are con-
verted into 16-bit binary data, which is input back to the internal register, and then
transferred to DM0011.
Note 1: The TBCD instruction can only convert data up to "#09999". When the
conversion of data of "#10000" or greater is attempted, special utility relay 2012
turns ON and the conversion is disabled.
Note 2: When the data in the internal register is not BCD data, special utility relay
2012 turns ON and the TBIN instruction is disabled.
Applications of TBCD instruction
■ Output of 4-digit BCD data
Outputs the current value of counter C001 to 0700 to 0715 in 4-digit BCD data.
Coding
Data is converted into BCD of "0" through "9999".
Data is converted into binary number of "0" through "9999".
