Hi, How can we trust the WBM from the PLCnext so that we don’ need to allow to go to the plc unsafe.
Hi, the problem is unfortunately typical for private networks and associated private certificates. From my point of view there are two possibilities to avoid the error. 1.) You can download the certificate from your browser (Chrome, Firefox etc.) or from the controller and import it on all devices. 2.) You can create a new private new CA and derive a certificate from it, which you exchange for the one on the controller. Then you have to import the CA on all devices that should access the controller. Special case, PLC with public IP address:
Here you could register a DNS name for the PLC and then use a public provider (e.g. Lets Encrypt). In this case only the certificate on the PLC has to be exchanged. Greetings Jan
