Setting the IP parameters
To enable a link to be established via OPC-UA, SIMOCODE pro V PN (GP) must have valid
IP parameters.
Example of the URL of the SIMOCODE pro V PN-OPC UA server:
opc.tcp://192.168.0.2:4840, where 192.168.0.2 is the IP address of
SIMOCODE pro V PN (GP).
The IP parameters, consisting of IP address, subnet mask, and router can be configured with
SIMOCODE ES and transferred to the device.
If SIMOCODE pro V PN (GP) does not obtain these parameters in another way (e.g. from
the controller via PROFINET IO), the "Overwrite IP parameters in device" parameter must be
activated under "PROFINET Parameters → IP Parameters."
Note
If the IP parameters are changed during an active OPC
-UA connection under "Online
→ Accessible nodes → Online & Diagnostics → Functions → Assign IP address", then
a restart is necessary with Commissioning
→ Command → Restart/Cold start.
Connecting to the SIMOCODE pro OPC UA server
Introduction
An OPC UA client can access process values in the hierarchical namespace of the
SIMOCODE pro V PN (GP)-OPC UA server.
To enable this, the OPC UA server and the OPC UA client authorize each other by
exchanging certificates. You can additionally encrypt the data traffic.
The SIMOCODE pro V PN (GP)-OPC UA server classes every certificate of an OPC UA
client as "trustworthy" by default.
Note
Configuring the connection on the client side
You can obtain information directly from the manufacturer of the software that is to access
the data of the SIMOCODE
pro V PN (GP)-OPC UA server via OPC UA.
