Direct Data Exchange; Modbus-Tcp; E-Mail; Server - DEUTSCHMANN AUTOMATION UNIGATE CL-Fast Ethernet Instruction Manual

Ethernet
* The port numbers (Destination-Port and Source-Port)
* At client operation TCP or at UDP the destination-IP-address
* The mode or the protocol of the channel:
0 = TCP-server,
1 = TCP-client,
2 = UDP,
3 = Channel not used (closed)
4 = RAW_MODE
Without these settings a connection to the Gateway cannot be set up via the Ethernet. Only
ICMP-data traffic (PING) is possible.

14.4.1 Direct data exchange

In the Ethernet the data from the RS-interface are represented unchanged via a TCP/IP connec-
tion.

14.4.2 MODBUS-TCP

The Modbus protocol is already available as Script for the serial interface for all Script gateways.
Now this additional function can be adjusted at the Fast Ethernet Gateway so that the Modbus
data can be made available as TCP-Modbus data packet on the Ethernet side.
(MODBUS-TCP).
For this purpose the channel that is used for this feature has to be set up as MODBUS-TCP
channel in the Script.
For this function a running Modbus-Script is required.

14.4.3 E-mail

On occurrence of particular events it is possible to send an e-mail to certain subscribers of a
mailserver. (The event is to be queried from the Script.) In the data that are received by the serial
interface or that are to be output at the serial interface certain characters or character strings can
be analyzed. On appearance of a particular sequence an e-mail that was prepared before and
that was written in the Script can be sent to one or several subscribers. For this purpose the
e-mail is sent to an E-mail-server.
This e-mail function is called up from the Script.

14.4.4 Server

14.4.4.1 Webserver

Websites can be called up through a communication channel that has been set up as webserver
channel via a Script. Here the internal data system is used. Several websites can be placed or
rather websites, image files and Java-applets can be called up. This way it is also possible to
represent the dynamically changing data of an application, that is connected to the serial inter-
face (shift register). Apart from that it is possible to remote-control an application with control ele-
ments on the website or to transmit data to this application.

14.4.4.2 FTP-server

For this function of the FTP-server 2 of the 4 available communication channels have to be set
up. One of the channels is in charge of the control, the other channel is responsible for the data
transmission. Once that the set up of the channels has been carried out initially in the Script, it is
possible on the Ethernet side to store files in the internal file system, to load files, to delete files
etc...with a FTP-client-program.
