OPC UA client - Loss of communication

Pascal

Dear Citect community,

I have a connection to an OPC UA server in a Citect project. Communication works well for about ten hours and communication stops for no reason, restarting Citect is necessary to restart OPC UA communication. To make sure it isn't a problem with the OPC UA server, I have installed on the same PC another client than Citect which doesn't stop and, in parallel, I made an identical connection on another Citect client which works perfectly !?

How can I 'trap' the origin of this communication stoppage?

  • Hi Pascal 

    I'm facing the same problem and I'm in contact with Citect support.

    Until now it apears to be related with "Cert private key is unreadable" hardware alarm, I'm using no security, but Citect is trying to look for a certificate.

    So I'm following here any answers, and I will keep you updated when I have news.

    Regards
