Display: Initialization Completed
Once initialization of the Ethernet or
Profibus module has been completed suc-
cessfully, the display shows "=".
Network module initialized
If initialization was not successful, no sym-
bol is displayed. The symbol does not indi-
cate whether or not a network connection
is active.
TCP Connections:
In the SBI operating mode, the Combics
breaks the connection automatically,
whether it is operating as a client or a
server.
In other operating modes; e.g.,
SMA, xBPI or Modbus/TCP, the connection
remains active until the computer (client)
disconnects it. Only one connection can
be active at any given time.
Combics 3: Initialization
Once initialization of the
Ethernet or Profibus module
has been completed successfully,
the symbol shown here is dis-
played continuously. When this
symbol is shown, the initialization
has been completed and the
device is ready for operation.
This symbol does not indicate
whether or not a network
connection is active.

Ethernet Interface: Features
Source IP:
IP address of the Combics indicator
If the address 0.0.0.0 is selected, an IP address should be allocated
dynamically by a DHCP server.
Source name: This parameter is optional. You can enter a name of up to 15 characters
=
for identification of the Combics. The name is passed to the domain name
system (DNS) server if:
– an IP address has been entered under DNS IP,
or
– an IP address has been allocated by a DHCP server.
Device port:
Port number on which the Combics listens for server operation.
Subnet mask: IP address mask for activating addresses in a subnet. If the mask is allocated
by a DHCP server, enter 0.0.0.0 here.
Gateway IP:
IP address of the gateway
Use the Target IP field to address a server in another network.
If the IP address is allocated by a DHCP server, enter 0.0.0.0 here.
DNS IP:
To address a DNS server explicitly, enter the IP address of that server.
If the address 0.0.0.0 is selected, the address will either be allocated by
a DHCP server or ignored.
Target IP:
Address of the server that receives data from the Combics.
This is important when the Combics is operating as client in SBI mode and
automatic data output is active. If you are using UDP, an address must be
entered here.
Target port:
Number of the port over which the server with the target IP receives data
from the Combics.
Protocol:
Select the transport protocol for transmitting data over Ethernet.
You can choose from the following:
– TCP: connection oriented; high data security
– UDP: connection independent (does not work with Modbus/TCP)
Mode:
Select the format used to embed user data in TCP or UDP (SMA for example,
will tunnel data over Ethernet when using TCP or UDP).
When using the XBPI or SMA protocol, Combics operates exclusively as
server. If SBI is used, the Combics is both server and client. In this case, the
Combics acts as client when the p [Print] key is pressed and when auto-
matic data output is active; for other operations, the Combics acts as server.
When Modbus/TCP is used, the Combics operates exclusively as server
(see also the operating instructions for the field bus module).
Power-up
response:
If the interface module is active, the display may take up to 20 seconds
longer to respond.
