Presentation, index 0x8020:02 / 0x8030:02

The measured value is output ex works in two's complement presentation (signed integer).
Index 0x8020:02 or 0x8030:02 offer the possibility to change the presentation of the measured value.

Signed integer presentation

The negative output value is represented in two's complement (negated + 1).
Maximum representation range at 16 bits = -32768 ... +32767_dec

Input signal		Value
(Index 0x8020:19, 0x8030:19) range: -10..+10 V	(Index 0x8020:19, 0x8030:19) range: 0..+10 V	Decimal	Hexadecimal
10 V	10 V	32767	0x7FFF
5 V	5 V	16383	0x3FFF
			0x0001
0 V	0 V	0	0x0000
			0xFFFF
-5 V		-16383	0xC001
-10 V		-32768	0x8000

Unsigned integer presentation

The output value is represented with 15-bit resolution without sign, therefore polarity detection is no longer possible.
Maximum representation range with 16 bits = 0 … +32767_dec

Input signal		Value
(Index 0x8020:19, 0x8030:19) range: -10..+10 V	(Index 0x8020:19, 0x8030:19) range: 0..+10 V	Decimal	Hexadecimal
10 V	10 V	32767	0x7FFF
5 V	5 V	16383	0x3FFF
			0x0001
0 V	0 V	0	0x0000
			0x0001
-5 V		16383	0x3FFF
-10 V		32767	0x7FFF

Absolute value with MSB as sign presentation

The output value is output in the signed amount representation: MSB=1 (highest bit) for negative values.
Maximum representation range with 16 bits = -32768 ... +32767_dec

Input signal		Value
(Index 0x8020:19, 0x8030:19) range: -10..+10 V	(Index 0x8020:19, 0x8030:19) range: 0..+10 V	Decimal	Hexadecimal
10 V	10 V	32767	0x7FFF
5 V	5 V	16383	0x3FFF
			0x0001
0 V	0 V	0	0x0000
			0x8000
-5 V		[-16383]	0xBFFF
-10 V		[-32767]	0xFFFF

	Presentation types The presentation types "Unsigned integer" and "Absolute value with MSB as sign" have no function for unipolar terminals. There is no change in the presentation in the positive range.
