Hello,

please read:

- opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...0Client-Server%20Security.html
- opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...%20Instance%20Certificate.html
- opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...html#Certificate%20Stores.html
- opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...ry%20Certificate%20Stores.html

Most likely what you need to do is find the rejected server certificate in the "RejectedCertificates" directory, verify that it is the one you really want to trust, and move it to ""UA Applications" directory.

Hi,

With the following code :
<?php
$Client = new COM("OpcLabs.EasyOpc.UA.EasyUAClient");
 
$EndpointDescriptor = new COM("OpcLabs.EasyOpc.UA.UAEndpointDescriptor");
$EndpointDescriptor->UrlString = "opc.tcp://CX-516F94:4840";
 
$ServerNodeId = new COM("OpcLabs.EasyOpc.UA.AddressSpace.UANodeId");
$ServerNodeId->StandardName = "Server";
 
try
{
    $NodeElements = $Client->BrowseObjects($EndpointDescriptor, $ServerNodeId->ExpandedText);
}
catch (com_exception $e)
{
    printf("*** Failure: %s\n", $e->getMessage());
    exit();
}
 
// Display results
foreach ($NodeElements as $NodeElement)
{
    printf("\n");
    printf("nodeElement.NodeId: %s\n", $NodeElement->NodeId);
    printf("nodeElement.NodeId.ExpandedText: %s\n", $NodeElement->NodeId->ExpandedText);
    printf("nodeElement.DisplayName: %s\n", $NodeElement->DisplayName);
}
 
?>

I obtaine the folowing error :
Description: OPC UA service result - {BadCertificateUntrusted}. The certificate is not trusted. --> {BadCertificateUntrusted}. Self Signed Certificate is not trusted. IssuerName: CN=TcOpcUaServer@CX-516F94, OU=Unit, O=Organization, L=LocationName, S=" ", C=DE, DC=CX-516F94.

I do not find/understand in the documentation how I have to manage the Certificate.

Thanks in advance for your help

Christian
