Valid Operands
Operand Function
S1 (Source 1) BCD data to convert
D1 (Destination 1) Destination to store conversion results
For the valid operand number range, see pages 6-1 and 6-2.
▲
Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
When T (timer) or C (counter) is used as S1, the timer/counter current value is read out. When T (timer) or C (counter) is
used as D1, the data is written in as a preset value which can be 0 through 65535.
Valid values for the source operand are 0 through 9999 (BCD). Make sure that each digit of the source designated by S1 is
0 through 9. If the source data is out of the valid range, a user program execution error will result, turning on special inter-
nal relay M8004 and the ERR LED.
Since the BTOH instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction
should be used as required.

When a bit operand such as I (input), Q (output), M (internal relay), or R (shift register) is
designated as the source or destination, 16 points are used.
When a word operand such as T (timer), C (counter), or D (data register) is designated as the
source or destination, 1 point is used.
