Mounting and Connection
The IBH Link UA is designed for DIN rail mount:
ATTENTION!
Use only supply voltage from 12V to 36V to operate the device. Higher voltage may destroy the device.
Power supply: 24VDC / 0,2A
Configuration of the IP addresses
The administration can be made with a recent web browser over the Ethernet port 1 by using the host name http://ibhlinkua_<serial number> (f.i. http://ibhlinkua_0001180)
or over the ports 2-4 by entering the default IP Address 192.168.1.14
No other tools are required.
Default IP Address configuration:
| Level | Port | Address |
|---|---|---|
| Management level | Port 1 | Host name: ibhlinkua_<serial number> |
| Control level | Port 2 - 4 | 192.168.1.14 |
Default Login:
admin

Network: Management Level
Network configuration for Port 1 (Management level respectively Supervision Level):
Network: Control Level
Network configuration for Port 2 - 4 (Control Level respectively Machine Level):
From both levels the Endpoint URL can be copied:
The Endpoint URL is provided by the IBH Link UA and is the destination URL for the OPC Client.
In our sample, the UA Expert diagnostic client from Unified Automation is shown:
Time Settings
Before creating certificates, the clock of the IBH Link UA must be set with the correct date and time!
Security
OPC UA defines different Security Levels:
There are different levels of encryption None, Basic128Rsa15 and Basic256
| None | No encryption |
| Basic128Rsa15 | 128 Bit encryption |
| Basic256 | 256 Bit encryption |
The IBH Link UA supports the level Sign, Sign and Encrypt and Sign + Sign and Encrypt
| Sign | The messages contain signed certificates |
| Sign and Encrypt | The messages contain signed certificates and are encrypted |
| Sign + Sign and Encrypt | The messages may contain only signed certificates, or can be signed and are encrypted as well |
Certificates
Before creating certificates, the time of the IBH Link UA must be set
Exchange of Certificates is another important security level of OPC UA.
A communication is only possible, if both Server and Client have a valid certificate assigned by the respective partners.
After setting the time of the IBH Link UA, a new server certificate can be created:
To get the best reliability of the Server Certificate, all fields need to be completed in detail:
If an existing Server Certificate shall be used with the IBH Link UA, it can be uploaded via the button <Upload Server Certificate>.
Make the IBH Link UA Server Certificate visible for the Client:
OPC UA clients usually detect server certificates automatically, when the first connection is established
or they offer other options for the handling of certificates.
Make the Client Certificate visible for the IBH Link UA Server:
After the client has accepted the server certificate, it will send the client certificate.
Whether new certificates are existing, can be checked using the Refresh button or the key <F5>:
Once the certificate is trusted, the communication with the Client can be established:
System
System information like the temperature of the IBH Link UA can be found here:
