Group Setting Description
Connection set‐
tings
IP address The IPv4 address of the company network interface,
since this is the primary server interface. This is deter‐
mined automatically.
Even if there is only one address stated in this dialog, the
OPC UA server is available at the following interfaces:
SINUMERIK 828D -X130
SINUMERIK 840D sl
without PCU/IPC
-X120
-X127
-X130
SINUMERIK 840D sl
with PCU/IPC
eth1
eth2
The OPC UA server is always available under the IP ad‐
dress of the network interface where the client interface
is connected.
Example for an 840D sl without PCU:
If the client runs on a device, which is connected to X130,
the OPC UA server can be addressed using the X130 IP
address. On the other hand, if the client is running on a
device in the X120 network, then the IP address of the
X120 interface must be used.
TCP Port TCP port at which the OPC UA server should be availa‐
ble.
Standard configuration: 4840
Note!
The port must also be open in the firewall. For PPU/NCU
this happens automatically. With PCU/IPC the port must
be opened manually in the firewall.
Message encryption It can be chosen which security endpoints should be of‐
fered from the server
