Post by sachem on SysFileGetTime problem ^{CODESYS Forge talk (Post)}
Good morning. I'm working with a Weidmuller controller using Codesys. My project use OPC-UA to communicate an application in my pc with the controller. Yesterday, I installed the license of the controller and test it, and the communication works perfect. I use the communication with anonymous login, and works fine. But, hours later, the anonymous login don't work, and the controller only allows connection via OPC with username and password. Someone know why this happend? Thanks

Same Issue here. If I understood correctly codesys plans to discontinue the classic SymbolConfigurations. But somehow, the CommunicationManager doesnt seem to support structures or arrays.

My colleague has found a tool online, Now it is possible to go to 4 GB instead of 2, which is plenty for now: https://www.techpowerup.com/forums/threads/large-address-aware.112556/ Use at own risk
