– (Data bits: 8, Parity: none, Stop bit: 1)
Number of bits onto which a character is mapped.
For the purposes of the parity check, the information bits are expanded by the parity bit.
The value of the parity bit ("0" or "1") completes the value of all the bits to obtain a pre-
arranged state. If the parity was not specified, the parity bit is set to "1" but it is not evalu-
ated.
The stop bits are appended to each character and signify the end of the character.
The delay time that must expire before a command is executed. The ZNA is specified in
units of 20ms.
Range of values: 0 ... 255
Default: 0
n
The character delay time (ZVZ) defines the maximum time that may expire between two
characters of a single telegram during the reception of the telegram. The ZVZ is specified
in units of 20ms.
When the ZVZ=0 the character delay time (ZVZ) will be calculated automatically (about
double character time).
Range of values: 0 ... 255
Default: 10
n
The delayed acknowledgment time defines the maximum time for the acknowledgment
from the partner when the connection is being established. The QVZ is specified in units
of 20ms.
Range of values: 0 ... 255
n Default: 10
