Post by alexgooi on OPC-UA Boolean format ^{CODESYS Forge talk (Post)}
Dear Forum, We are currently making the switch from OPC-DA (Codesys server) to OPC-UA (Running on a Codesys controller). We are using Codesys version 3.5 SP 20. Our Scada system is expecting Boolean's to be represented as a 0/1 (True Boolean) but the OPC-UA server is representing a boolean as False/True This indeed matches the OPC-UA standard, but is there a way to configure the OPC-UA server's boolean representation? Thank you in advance

Thank you for your answer. I did install certificates, especially for OPC UA Client/Server tests. This OPC UA PubSub test uses pre-shared keys, not certificates. By the way, I do you 3.5.22 patch 2.

Post by macman on Codesys 3.5 OPC UA Client to Kepware OPC UA Server ^{CODESYS Forge talk (Post)}
Hi, I have problem with connecting Wago PLC WAGO 750-8212/0025-0002 configured as OPC UA client to Kepware OPC UA Server. I am using Codesys 3.5.19.70. What I did so far. To the Codesys project I added object Data Source Manager and configured connection OPC UA like below: pic 1 Then I can browse the OPC server tags in “Variables” tab after prior trust on the server side of the client certificate created in the “Communication” tab: pic 2 Additionally second certificate has been created in Codesys for runtime process in “Security screen” as well as the server certificate was approved here: pic 3 But when I compiled project, downloaded it to PLC and go to RUN I can’t read selected in “Variables” tab, OPC Server tags. I am getting such error (ID: 7001): pic 4 All two PLC certificates has been trusted in OPC server (Kepware) side: pic 5 and Kepware server configuration look like this: pic 6 I can easily connect using third party OPC UA client UaExpert to Kepware server without problem. In attachment I added also log from Kepware OPC UA server. pic # - this specifies the number of a concrete graphic from one of the collective in attachment
