Call Routines 0–68 12
12 -7
Use this routine to convert 16-bit binary from PLC processor to BASIC
floating point. See also CALL 21.
See Chapter 8 for more information.
Input and Output Arguments
This routine has one input and one output argument. The input argument is
the number (1 to 64) of the word in the write-data-transfer buffer you want
to convert from 16-bit binary to BASIC format. The output argument is
the value converted into BASIC floating point format. There are no sign
or error bits decoded.
Syntax
PUSH number of word (1 – 64) to be converted
CALL 11
POP converted value
Example
> 10 PUSH X
> 20 CALL 11
> 30 POP Y
Use this routine to convert 4-bit octal from the PLC processor to BASIC
floating point. See also CALL 22.
See Chapter 8 for more information.
Input and Output Arguments
The input argument is the number (1 to 64) of the word in the processor
block-transfer buffer you want to convert from 4-digit signed octal to
BASIC floating point format. This 12-bit format has a maximum value of
+7777 octal. The output argument is the value converted into BASIC
floating point format. The sign bit is bit number 16.
Syntax
PUSH number of word ( 1– 64) to be converted
CALL 12
POP converted value
Example
> 10 PUSH X
> 20 CALL 12
> 30 POP Y
