UDP
The device requires from the user the IP address and the port number of the communication partner. In the
same way, the host system (PC/control) also requires the set IP address of the device and the selected
port number. By assigning these parameters, a socket is formed via which the data can be sent and re-
ceived.
Ä
Activate the UDP protocol.
Ä
Set the following values:
ð
IP address of the communication partner
ð
Port number of the communication partner
The corresponding adjustment options can be found in the webConfig tool:
Configuration > Control > Host > Ethernet > UDP
TCP/IP
Ä
Activate the TCP/IP protocol.
Ä
Set the TCP/IP mode of the device.
ð
In TCP client mode, the device actively establishes the connection to the superior host system, e.g.,
PC/control as server. The device requires from the user the IP address of the server (host system)
and the port number on which the server (host system) accepts a connection. In this case, the de-
vice determines when and with whom a connection is established.
ð
In TCP server mode, the superior host system (PC/control) actively establishes the connection and
the connected device waits for the connection to be set up.
The TCP/IP stack must be informed by the user as to the local port of the device (port number) on
which connection requests from a client application (host system) are to be received.
If there is a connection request and a connection is established by the superior host system (PC/
control as client), the device – in server mode – accepts the connection. Data can then be sent and
received.
Ä
With a device as TCP client, set the following values:
ð
IP address of the TCP server, normally the IP address of the control or the host computer
ð
Port number of the TCP server
ð
Timeout for the wait time for an answer from the server
ð
Repetition time for renewed communication attempt following a timeout
Ä
With a device as TCP server, set the following values:
ð
Port number for the communication of the device with the TCP clients
The corresponding adjustment options can be found in the webConfig tool:
Configuration > Control > Host > Ethernet > TCP/IP
8.4.5
FTP client
To transfer images and log files, you can configure process data output via an FTP server.
Ä
You can set the IP address and the port number of the FTP server with which communication is to oc-
cur.
Ä
Assign user names and password settings or define the direction of communication using the
Passive
mode
option.
ð
When the
Passive mode
option is activated, the FTP client sets up an outgoing connection to the
server.
Ä
Activate the FTP client.
Ä
Select which images (OK/NOK) are transferred. You can assign each one a name.
The corresponding adjustment options can be found in the webConfig tool:
Configuration > Control > Host > FTP client
NOTICE
Ä
You can set the time stamp via
Maintenance > System clock
.
ð
The system clock is reset if the operating voltage is interrupted.
