Module: Modbus® (Modbus)
Parameter Description Setting range Default Menu path
t-timeout Within this time the
answer has to be
received by the SCADA
system, otherwise the
request will be
disregarded. In that case
the Scada system
detects a communication
failure and the Scada
System has to send a
new request.

Physical Settings Digit 1: Number of bits.
Digit 2: E=even parity,
O=odd parity, N=no
parity. Digit 3: Number of
stop bits. More
information on the parity:
It is possible that the last
data bit is followed by a
parity bit which is used
for recognition of
communication errors.
The parity bit ensures
that with even parity
("EVEN") always an even
number of bits with
valence "1" or with odd
parity ("ODD") an odd
number of "1" valence
bits are transmitted. But it
is also possible to
transmit no parity bits
(here the setting is "Parity
= None"). More
information on the stop-
bits: The end of a data
byte is terminated by the
stop-bits.
