3.3 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)
