NONE; EVEN; UNEVEN
• Available in the ASCII transfer mode * even or uneven parity bit
(EVEN, UNEVEN).
• Available in the RTU transfer mode * no parity bit (NONE) or even
or uneven parity bit (EVEN, UNEVEN).
Factory setting: EVEN
Select the byte transmission sequence for the Integer, Float and String
data types:
0 - 1 - 2 - 3
3 - 2 - 1 - 0

For entering a delay time after which the measuring device replies to
the request telegram of the MODBUS master. This allows
communication to be adapted to slow MODBUS masters:
0 to 100 ms
Factory setting: 10 ms
