PROFIBUS protocol via the context menu. However, only PROFIBUS set-
tings can be chosen afterwards.
PROFIBUS communication is limited to fixed communication para-
meters. Therefore, the interface mode cannot be changed after the
protocol has been created, i.e. the channel only functions as
PROFIBUS.
UART settings
Baud rate
l
The baud rate states the number of characters transferred per second. Selec-
tion depends on the properties of the connected devices and the cable length
between the devices: For longer lines, a lower baud rate should be selected
to achieve error-free communication. Usually a maximum 20 m are permitted
for a RS232 connection.
Data bits
l
Sets how many bits can be used for a data transmission, whereby the default
setting is 8.
Handshake
l
Sets how the data flow is controlled. You can choose between none (without
control), Xon/Xoff (software handshake) and RTS/CTS (hardware hand-
shake), whereby the default setting is none.
Parity
l
Sets whether a parity bit accompanies a transmission and how it is determ-
ined. The default setting is none.
Stop bits
l
Sets the number of stop bits, which are the default setting.
