Profi Message
The COM connection is indicated in the Channels tab with the COM symbol .
The COM connection is available in the channel view under the interface entry.
Double-click a COM entry or select Properties from the context menu to display the
configuration dialogue. We recommend giving a unique channel name, amending
the
Description and, if necessary, entering a Location .
Main settings tab
Interface mode
You might not make a choice for some COM interfaces, depending on the device, as
there is only one setting available. Otherwise, select whether the connection is for
PROFIBUS devices (selection
PROFIBUS or PROFIBUS logger ) or you want to give
settings freely for other protocols ( Modbus , user-defined )(selection UART ). Addi-
tional fields are displayed depending on your selection, e.g. to set interface para-
meters such as baud rate, number of data bits, or parity. You can also create a
channel with PROFIBUS protocol via the context menu. However, only PROFIBUS
settings 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.
A change of the interface mode is only possible after protocol is
deleted.
UART settings
l
Baud rate
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.
l
Data bits
Sets how many bits can be used for a data transmission, whereby the default
setting is 8.
l
Handshake
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 .
l
Parity
Sets whether a parity bit accompanies a transmission and how it is determ-
ined. The default setting is
none .
