Htob (Hex To Bcd) - IDEC FC4A-C10R2 User Manual

ATA
Introduction
Data conversion instructions convert data format among binary, BCD, and ASCII.
The ENCO (encode), DECO (decode), and BCNT (bit count) instructions processes bit operand data.
The ALT (alternate output) instruction turns on and off an output each time an input button is pressed.

Valid Operands
Operand
S1 (Source 1)
D1 (Destination 1)
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 (270Fh). Make sure that the source designated by S1 is within the
valid value range. If the source data is out of the valid range, a user program execution error will result, turning on special
internal relay M8004 and the ERR LED.
Since the HTOB 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 input is on, the 16-bit data designated by S1 is converted into BCD and
*****
stored to the destination designated by operand D1.
Valid values for the source operand are 0 through 9999.

Function
Binary data to convert
Destination to store conversion results
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.
