14: DATA CONVERSION INSTRUCTIONS« FC4A MICRO SMART USER ’S MANUAL » 14-3HTOA (Hex to ASCII)Applicable CPU ModulesValid OperandsFor the valid operand number range, see pages 6-1 and 6-2.When T (timer) or C (counter) is used as S1 or S2, the timer/counter current value is read out.The quantity of digits to convert can be 1 through 4. Make sure that the quantity of digits designated by S2 is within thevalid range. If the S2 data is out of the valid range, a user program execution error will result, turning on special internalrelay M8004 and the ERR LED.Since the HTOA instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instructionshould be used as required.Valid Data TypesFC4A-C10R2/C FC4A-C16R2/C FC4A-C24R2/C FC4A-D20K3/S3 FC4A-D20RK1/RS1 & FC4A-D40K3/S3X X X X XOperand Function I Q M R T C D Constant RepeatS1 (Source 1) Binary data to convert X X X X X X X X —S2 (Source 2) Quantity of digits to convert X X X X X X X 1-4 —D1 (Destination 1) Destination to store conversion results — — — — — — X — —W (word) I (integer)X —S1 → D1, D1+1, D1+2, D1+3When input is on, the 16-bit binary data designated by S1 is read fromthe lowest digit as many as the quantity of digits designated by S2, con-verted into ASCII data, and stored to the destination starting with theoperand designated by D1.The quantity of digits to convert can be 1 through 4.HTOA(W) S1*****S2*****D1*****When a bit operand such as I (input), Q (output), M (internal relay), or R (shift register) isdesignated as the source, 16 points are used.When a word operand such as T (timer), C (counter), or D (data register) is designated as thesource or destination, 1 point is used.
