Thus I wrote a binary search tree in C that uses this struct: struct tnode { int content; struct tnode *left; /* left tree part */ struct tnode *right; /* right tree part */ }; My primary method: int main() { struct tnode *Baum = NULL; struct tnode *tmpPos = NULL; Baum = addelement (Baum, 32); Baum = addelement(Baum, 50); Baum = addelement(Baum, 60); tmpPos = searchnode(Baum,50); } So, in essence, this generates a Binary search tree with three components (32,50,60). According to this post, my searchnode function is intended to move a reference to the "50" so that I may delete it afterwards. My searchnode Method, on the other hand, only provides the pointer if the element I'm looking for is the root of my binary search tree.searchnode: struct tnode *searchnode(struct tnode *p, int nodtodelete) { if (p == NULL) { printf("Baum ist leer oder Element nicht vorhanden \n"); } if ( p -> content == nodtodelete) { return p; } if (p->content >

I have two servers running KepServerEX, LinkMaster and Redundancy Master. They are a redundant pair to ensure uptime.  I am looking to upgrade these server's to a new OS (Windows 2019 Server Datacenter). I know Redundancy Master does not work properly on anything past Windows 2016.  I am looking for options to replacing the functionality of these obsolete software packages. I am trying to avoid different vendors if at all possible.  I specifically need the ability to write data from one PLC in the mill to another. Most of these are between ControlLogix Processors and I need to be able to get data into specific programs, which LinkMaster does easily.  I use Redundancy Master to mirror DCS connectivity servers for KepServerEX and LinkMaster, so that if we have to take down one server in the pair, the OPC data can continue to be provided. The nice thing about Redundancy Master is that it is seamless to the other applications.  I have looked though t

Hello, One of my users has started facing a strange problem since our upgrade from 9.1 to 9.3 with the file upload widget. The upload always fails with a response of "bad request".Looking into the dev tool a bit more I noticed:There is no "upload-repository" in the payload. I have tried the same upload widget with my own user and can't replicate the issue:As you can see I do get the "upload-repository" in my payload. I have checked and the user does have permissions to the repository, both visibility and run time.They do not have design time permissions set though, perhaps something has changed between 9.1 and 9.3 that would require design time permissions for repositories now? If anyone has had the same problem and found a solution, please write a post here.Eventually I'll open a ticket with PTC and if they can find the issue I'll report the solution here. Thanks,Jens
