Data types

Data values are classified according to data types for transmission. Only characters which can be represented

in ASCII are permitted.

w

BCD

Floating Point number in BCD-ASCII format,

Range: -9999 ... -0.001, 0, 0.001 ... 9999

optional: negative polarity sign and decimal point permitted; exponent representation not permitted.

KS800 controllers with an accuracy of max. 4 digits. With received data, number of digits and decimal

point position are not fixed and depend on the FP resolution. The values are not rounded off.

Switch-off value for BCD data is : -32000

w

INT

positive integer number in ASCII format

Range: 0 ... 32767

Range with configuration words: 0000 ... 9999 (Ä page 14)

Exception: switch-off value ‘-32000’

w

ST1

Status, bit-oriented, 1 byte length

Range: 00H ... 3FH, transmitted: 40H...7FH

Only 6 bits for transmission of information can be used, i.e. bit 0...5 (LSB = bit 0). Bit 6 must always be

set to ‘1’, in order to avoid confusion with the control characters. Bit 7 contains the parity bit.

w

SYS16

System identification number, 16 bytes

Format: xx,yyyyyyyy,zzzz (Ä page 11)
