Ethernet and serial (RS232C, RS485, USB) ports

13.1 General information on the Ethernet and serial ports

13.1.1 Server

a) MEWTOCOL communication with the PLC
FP Web-Server V2.810 EN
The FP Web-Server can work as an Ethernet-to-serial interface converter.
Thereby all data the FP Web-Server receives via an Ethernet port, e.g.
from a computer, is routed to its respective port (RS232C, RS485 or USB)
and vice versa, i.e. all data received at the serial interface is sent back to
the computer via Ethernet. In this configuration the FP Web-Server is the
server and the computer is the client.
To set up an FP Web-Server port as a client, refer to
enable transparent TCP/IP client port. With two FP Web-Server units set up
as a pair (transparent port server and client), two FP-Sigmas can
communicate with each other via the PLC link function (PC link protocol).
(Take into account the timeout set in the PLC.)
For a detailed description refer to the online help under the keyword
"Configurator parameters to the MEWTOCOL port server" or "Configurator
parameters for the transparent port".
For this kind of data exchange, the FP Web-Server provides two special
Ethernet (i.e. TCP/ IP) server ports that wait for an incoming connection
from a client, e.g. a computer or an FP Web-Server configured as a port
client:
 Depending on the PLC interface setting, communication with the PLC is
carried out via the 3-pin RS232C of the FP-WEB2 or the 3-pin RS485
port of the FP Web expansion unit
 Preset TCP/IP port number 9094 (server)
 Up to 10 client connections are possible (TCP/IP)
 MEWTOCOL protocol for data and program exchange
