Network Functions and Communication
9 Network services
If no controller is connected to the BDTP client (terminal), the inverter/PLC 1 and
inverter/PLC 2 units must be dragged from the RS-232C / RS-422 / RS-485 interfaces
to "Unused functions" in the [Peripheral configuration] dialog. Invoke this dialog from
[Setup] / [Peripherals] from the dialog.
BDTP server Manages requests from clients: supplies clients (terminals) with information after a
request from a client (terminal). Click on Edit and enter the port. This value usually need
not be changed.
Parameter Description
Server port Communication port for the BDTP server. Usually need not be changed.
Max. clients Maximum number of BDTP clients (terminals) in the network.
Data register The values in the data register can be transferred between a server and various
clients in the network.
The first register in the register block of the server that is to be transferred to or from
the specified client is defined under Data register. The register type must be the same
for client and server.
Data transfer can only be controlled from the clients.
For further information on data transfer, refer to section "BDTP client" on page 249.
Clock server Specify whether you want all other clients in the network to be synchronized to the
current server clock.
See also section "BDTP client" on page 249.
FTP server This function allows for transferring data from a PC to and from the terminal. The FTP
server in the terminal supports data transfer in passive mode (PASV). The passive mode
should be used if the terminal is not connected using PPP connection. This is necessary
because it is not possible to determine in advance which components are connected
between client and server, e. g. router based firewalls or gateways.
Using passive mode eliminates several errors. Web browsers use this mode as
standard. Passive mode can also be used with PPP connections. National special
characters in file names are not supported. The terminals use files without date.
For further information on the FTP server in the terminal, refer to chapter 9.3 "Network
functions in the terminal".
