Data types

Data values are classified in data types for transmission.

w

FP

Floating point number (Real)

Range:as integer (in individual access) -9999 ... 0 ... 9999

as fix point-3000,0 ... 0,0 ... 3200,0

Exception:switch-off value ‘-32000’

w

INT

positive integer number

Range: 0 ... 32767

Range with configuration words: 0000 ... 9999 (Ä Page 27)

Exception: Switch-off value ‘-32000’

w

ST1

Status, bit-oriented, 1 byte Length

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

Only 6 bits can be used for information transmission, 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

ICMP (Integer Compact)

Bit information as integer transmission, max. 15 bits

Range: 0...32767; integer transmission is in ASCII format.

fixed to ‘0’
